Features & Specifications

A team OSD favorite, the AMP200 is a high current 2-channel amp with loads of features. This amp lets you home run (directly to the back of the amp) two pairs of speakers or 4 speakers total. Since it's high current, you can add up to 4 pairs of speakers (8 speakers total) by adding OSD speakers selectors such as the DSM4. Rated at 80 Watts per channel at 8 ohms, the OSD-AMP200 is overload stable so it’s ideal for use anywhere clean power is needed. It also includes a dual source switching circuit. When you connect two independent sources number (say your iPod and a TV in another room) source one takes priority when it is active. When source one is turned off, source number two comes on. Note: You cannot play two sources simultaneously. For this feature you need a multi-channel amp like our MX1260. Step-up features rarely seen in amps of this price range include a built-in voltage meter, and front mounted volume and balance trim controls.


Other Product Info

The OSD Audio AMP200 is a powerful, high current amplifier for home and pro-installation applications. It is a high current (2 Ohm Stable), two channel power amplifier, which is overload stable. It is ideal for use as a remote amplifier, or as a single or dual zone amplifier with a built-in meter.

Rob S.

October 26, 2017
Hi. I have pre-wired my house for 8 zones. 6 regular stereo zones. 2 of the zones are actually split, one speaker to a bathroom, the other to one of the kid's bedrooms, this times 2. I hope that wasn't a bad idea. Each zone has wiring for a volume control. All leading back to the laundry room where I will have the equipment. So, is the AMP200 a good choice? Would AMP120 be underpowered? While I have you, would the DSM8 be a good speaker selector choice? My source A will be an Amazon Dot. My source B will come from the living room stereo to hear the TV, Turntable etc. As far as volume controls, is the VMS60 okay or do I need the VMS100? For speakers I was looking at the ACE600. I don't want them too huge, but I want them to sound decent, but audiophile isn't necessary. Thanks in advance.
1 Answers
Hi Rob: The AMP200 would be a minimum that you would want for your setup. And to do two source properly you would need 2 of them but you can start with a single amp to start with but would be limited to listening to either the Dot or the equipment from the Living room Receiver. The AMP200 features automatic source switching between two sources with input #1 taking priority over line 2 input. The DSM8 features Dual Source (dual Amp) switchable per zone (A or B). Always go with the biggest Impedance matching Volume Control so either the VMS100 or even VMS300. So lastly, are you saying you actually have six zones with two of the zones splitting between two rooms? Did you run four conductor to each (I hope) and not 2 conductor to each so right channel to the bathroom and left channel to the kids room as an example; please confirm? You may be able to go with the DSM6 versus the DSM8. Look at the ACE640 over the ACE600, a little better components and a true second order crossover. For the bathrooms take a look at the ICE800TTWRS ( a weatherproof speaker) or the MK690TT (which trim-less design would match the ACE640). let me know if I can be of further assistance... TL/4611

When using this to power multiple pairs of speakers through a speaker selector, do you just use the speaker A outputs? In that scenario, how much power is actually getting to each speaker (assume 4 pairs of 8 ohm speakers) ??
1 Answers
Hi Ray: Yes you would connect to either speaker A or Speaker B. In some cases you could connect the speaker selector (depending on the speaker selector and how it is configured) to Speaker A and still connect a single pair the Speaker B. Regarding the question of output per channel there are several factors involved to determine what that would be. What Speaker Selector you are using, Are you using Impedance matching Volume Controls either internal or external or are you using a simple Speaker Selector like our IS4 with internal protection. I do think the AMP200 will have plenty of output for most anything you can connect to it. And if you think you might still need more then go with the AMP300. TL/4484

Does it work with an audio source that will feed the RCA in with 2.0V RMS
1 Answers
HI Bruno: There is no limitation on input signal. Typically the higher the input the the better especially when you have adjustable Master Gain controls on both the AMP200 and AMP300. It allows you to turn the gains down on the AMP which is much more effective versus having a lower input and then have to overdrive the internal gain controls. You have greater headroom available to you. It is like adding an additional pre driver to your signal path. Typically when you add a good pre amplifier to your system you are looking to increase in input signal to the amplifier like you are doing. TL/4408

Hello, Can this amp run both speaker A and speaker B at the same time (8 ohm load)? My AMP 100 when selecting speaker A, speaker B button pops up so both (speaker A & B) can not be run at the same time.
1 Answers
HI Tom: The AMP100 (AudioSource) like our AMP120 are chip amps which we do not recommend running both speaker A and B at the same time since the amp like to see only an 8 ohm load and the two pair A+B are in parallel lowering the impedance to 4 ohm. So we purposely design the buttons so you can not push both in at the same time. You can but we do not recommend it. The AMP200 is another amplifier all together that is true High Current Amplifier which is stable down to 2 ohms. You would have no problem connecting two pair to Speaker A and adding a third pair to speaker B and playing all three pair at once. The amp would see a 2.6 ohm load. As the impedance drops the demand for current increases. Higher current means higher temperatures and the AMP200 features ample internal heat sink to absorb and dissipate the extra heat. The AMP200 weighs 24 pounds versus 9 for the AMP100/120. To top that the sound quality is a night and day difference. The AMP200 and AMP300 are true High Current Audiophile Amplifiers. Great choice... TL/4354

A lot of money for just watts, do you have a model with a tuner?
1 Answers
Hi Jim: This is a true A/B audiophile Sound Quality Amplifier. It features a Large High Power Toroidal Power Supply typically found in much more expensive amplifiers. It also has substantial internal capacitance and uses nothing but true discrete components; no IC's in the studio section. It is considered a High Current Power Amplifier which increase the amount of output current as you lower the impedance. Note it is 2 ohm stable. It is really meant to run at 4 ohm to get your monies worth. It will drive three pair of 8 ohm speakers in parallel (for a 2.6 ohm impedance). It contains plenty of internal heat sink where the Fully complimentary Bi-Polar output devices are mounted directly to the metal. It weights more than 24 pounds nearly three times as much as the AMP120. I tell people connecting the AMP200 at 8 ohm is like buying a Corvette and driving it at 35 miles an hour on the freeway (in your case the I5 or 205). This has been a real workhorse for us. It is the number 1 amplifier I recommend in the Upload Your Plans System Designs. Great Choice TL/4150

Since your Amp300 is out of stock I'm looking for another option for my application. I want to use the amplifier for a whole house distribution. I have 4 volume controls with 1 pair of speakers connected to each and one volume control connected to 2 pair of speakers. They are all 8 ohm 100 Watt max speakers. I just purchased your ISSSB speaker selector. Can I use the AMP 200 in this application instead of the AMP300?
1 Answers
Hi Joe: Yes the AMP200 will work fine for your application. The AMP200 like the AMP300 is a High Current Power Amplifier. Normally when using a standard amplifier you would set your Impedance Matching Volume Controls setting to 8X on all 5 Volume Controls for your 6 pair of 8 ohm speakers (5 zones). But the High current amplifier will allow you to set them to 4X so you will get more output. Note, the impedance matching volume controls do not turn off when you rotate the knob so you have no audible sound coming out of the speakers. That is why it is a good idea when you are not listening to a zone or zones you want to use the on/off switch on the Speaker selector to turn the zone/room off. Good choice, you will not be disappointed TL/3692

Hello, I am trying to wrap my mind around setting up a 4 zone set up. I am looking to use a speaker selector with built in volume control. Would this amp the AMP 200 be the a good choice for my system. The speakers are just standard type and nothing super fancy. They run at 130 watts maximum power capacity, 40 watts nominal. Arethere any tips on the amp set up? Attached is the speakers I am wanting to run. Thanks Bryan
1 Answers
Hi Bryan: The AMP200 would be an excellent choice along with our SSVC4 4 zone speaker selector with internal volume controls and dual source capability. Your picture shows four speakers. Typically a zone would consist of a stereo pair per zone. So do you have four more speakers for a total of eight speakers or stereo four pairs. Both the AMP200 and SSVC4 have stereo connection, right channel (+/-) and Left channel (+/-). I would be more than happy to provide you additional information on wiring and setup. One small question regarding your picture, you show a spool of speaker wire, is it CL2 or CL3 rated? I am assuming these wires will run through a wall at some time so that is important. It should say on the label. TL/3661

I am really interested in this amp but am confused. I have three pairs of Polk Patio 25 speakers that are 8 Ohms and 150W that I would like to power with this amp. All six speakers will be on at the same time. Can this amp effectively power these 6 speakers or do I need an amp with more channels? If so, how do I need to wire the speakers and is there any other equipment that I need?
1 Answers
Hi Chris, This amplifier will have no problem driving three pair of speakers. We suggest connecting two pair to Speaker A output (in Parallel, Positives to Positives and Negatives to Negatives) and the third pair to Speaker B. With only Speaker A playing, the two pairs in parallel will create a 4-ohm load and increase the output of the amplifier from 85 watts a channel to 125 Watts a channel because the load increases the current demand. Add the third pair of speakers to Speaker B and play both at the same time and you increase the current demand some more. This High Current Amplifier features a large Toroidal Power Supply, ample internal capacitance, all discrete components and a large internal heat-sink to handle the increased current demand from the 4- to 2-ohm load. It will also provide audiophile sound quality when using all discrete components in the audio section. There is a reason why this amplifier weights and costs almost three times as much as a chip amplifier. Other features include Automatic Source Switching, separate Right and Left Master Gain controls and three options for turn on (ON, Auto Sensing or 12-volt trigger). You will not be disappointed with this amplifier; it is a great choice! TL/MA -1401

Is this amp powerful enough to power 8 pairs of speakers with volume controls connected to speaker selector?
1 Answers
Hi Wojtek, There should be no problem. Just use impedance-matching volume controls. We also recommend using our DSM8 and disabling the protection circuit of the speaker selector. Make sure you set the volume controls to 8X. You can also set them to 4X for more power out of the AMP200. You could even utilize two DSM4 speaker selectors (again defeat protection). Connect one DSM4 to Speaker A and the second DSM4 to Speaker B. Be sure you set impedance-matching for all volume controls settings to 4X. TL/MA 1261

I just connected this AMP to a SONOS Connect and set the amp up for "Auto Sense" mode. The music plays fine but when I stop the music or even remove the RCA source cables all together the AMP never goes to standby. Does anyone have an idea as to why?
1 Answers
Hi Judd, Here’s what’s happening. When you switch between 12-volt trigger (and it goes instantly to red, stand-by mode) then auto sensing and power on to blue, you will hear the amp click internally. This is normal operation. The 12 volt is a hard-wired trigger so it instantly goes to stand by. The way the auto sensing works is that it takes between 6 to 15 minutes to go to stand by; otherwise, you might have the amp constantly going back and forth between On and Standby, depending on the music. If you were listening to classical music, it might click on and off several times. Try it again but see how long it takes your unit to go into standby. Our AMP200 on the test bench took exactly six and a half minutes. TL/MA

Is this really a four channel amp? Can it play four different sources independently simultaneously (80x4) for bi-amplification configuration?
1 Answers
Hi Geofferey: No, this is not a true four channel amplifier based upon your scenerio. It is a two channel amplifer that has a choice of A, B or A +B speaker output. The dual source feature is an automatic switching circuit. When you connect two independent sources number one takes priority when it is active. When source one is turened off source number two if active comes on after a short delay (adjustable 3 to 15 seconds). Then if you activate source number one again it comes on instanly. So you can only play one source at a time. You also have theoption to connect speaker level for one of your sources. Another key to this amplifier it is a High Current Amplifier that is 2 ohm stable. You could connect three 8 ohm speakers in parallel to one of the speaker outputs (A or B) or connect two pair of 8 ohm speakers in parallel to each speaker output (A + B). This is a true audiophile amplifier featuring a large Toridal Power Supply, ample Capacitance and large internal Heatsinks typically found on more expensive amplifiers. Add to that the unique features including the three turn on options (On, Auto/Music Sensing or 12 volt trigger) you have flexible amplifier providing great performance and value TL

How do I connect a subwoofer to the AMP200? George
1 Answers
HI George: There are two ways depending on the options available to the Subwoofer you are planning on using. The first connection is to connect your sub woofer to the Line 2 output of the AMP 200 featuring two female RCA connections for right (red) and left (white). This is called a signal/line (low) level or Pre Amplified. This is connected to the stereo inputs of the sub woofer. It is obviously a full range signal that is sent to the sub woofer, not LFE controlled (Low Frequency Effects) that you would associate with a sub output of an AVR (Audio Video Receiver). Note; the output of the Line 2 is limited to the input of Line 2. It essence it is a pass through of whatever is connected to Line 2 input. There is no signal from Line 1 input. The second option actually affects both line 1 and line 2 output. It is where you connect to the Speaker B output to a Powered sub woofer that has a speaker (high) level input. Use when line level outputs are not available from your receiver, pre-amp or power amp. Your existing stereo speakers can share these terminals allowing you to add bass to any stereo or home theater system. Do not use if Line level Inputs are connected. You could connect your speakers to Speaker A and your Sub woofer to speaker B. I hope that makes sense... TL/4624

1 Answers
Hi Vickie: When you mean the same source are you connecting the Speaker Selector to a Zone 2 speaker Level output from a Audio Video Receiver. If this is the case then you can purchase whether a AMP 200 or Amp 300 to connect to the Zone 2 Pre amp output of your AV Receiver. Then you could still have your Airport express connected to the receiver. You can also start from scratch and use our AMP200 or 300 and connect directly to your speaker selector. You could then connect the Air Port Express directly to the AMP200/300 using a 3.5mm to RCA adaptor cable. I am assuming your Speaker Selector is a Niles unit as well with switchable protection on the back. The switch gives you four options; 1 pr, 2 pr, 3-4 pr and 5-6 pair. Even though you are powering 5 pair you can set the selector to 3-4 pairs so you get more output from the AMP200/300. Let me know if there is anything else I did not cover: TL/4339

You can drive a 2 pair off speaker A and 1 pair of of speaker B and play both A and B at the same time.You could drive all three off Speaker A but could not use Speaker B. Both these amplifiers are High Current (needed to play at 2 ohm) total discrete components, ample internal heat sinking and lots of internal capacitance.

Would the AMP200 be able to power the subwoofer in addition to my 2 front speakers? Also, which subwoofer do you recommend of the two noted? The location would be lower front left corner of room approx. 12' from seating. Thank you for your help!
1 Answers
Hi JR: Good question, but I do not believe the AMP200 will help you out. Plus placement of your sub woofer can be critical. The advantage of the bulky sub woofer is you have the ability of determining where the best location (for most bass) is for your room being it is a self powered dedicated enclosure. Of course since you already have it you can place the bulky sub in front of the location you are planning to install the sub in the wall and see how it sounds compared to its original location. The problem with the low frequencies is the size of the sign way that can create dead zones in the room. Which is one of the reasons most receivers have two sub outputs (not to just sell you another sub). So if you can determine the location to add an in-wall sub will work. You will need an external dedicated mono sub amplifier complete with crossover, gain and phase control to power it. The latest craze is to have one sub connected to sub 1 output and a second sub connected to your center channel. I am assuming you are using the AMP200 for Right and left front and the external amplifier for your center channel. This would leave a pre amp connection for your center channel to output to your powered sub or external sub amp with a in-wall sub like our IWS10. Both the Pre amp and speaker level outputs are hot at the same time. on most Receivers (check your owner's manual to be sure). If you don't have the owners manual you can easily download one on line.

It will not handle 4 pair in parallel unless you use either a high power speaker selector or speaker selector with impedance matching Volume controls. You could use an impedance matching Volume Control on on two pair and connected to Speaker output A and a second two pair on a impedance matching Volume Control connected to Speaker B. Both Volume Controls would need to be set to 4X. This amp is built to run at 4 ohm load all day long.

Hi Drew: Connect the AMP200 (Line 2 input) to your two channels (Front Right and Front Left Speaker pre amp outs) and turn the volume knob on the front panel to max all the way clockwise. This knob works like a Volume Control where you are turning the volume down ( attenuate the volume). It does not add gain. Then adjust the volume level on your receiver (the other channels not connected to the AMP200)Set the volume levels for the two front channels to match the volume levels of the other channels. Now adjust your left and right master gain levels turning them clockwise to a level where it sounds like your are clipping, then back it off slightly. Turn your front panel volume level to 12:00 o'lock (halfway). Now you can start your calibration so all the channels will be calibrated. Good luck... TL/4114

I am interested in running 2 pairs of 8-ohm 75w omni-speakers with this amp. At 4-ohms it looks like it has the power to do this. Would I hook all four speakers to speaker A (or B) rather than 1 pair to A and 1 pair to B in order to create this load? Or what would be the best configuration to maximize this system. The speakers will be outside on the pool deck, and there is a decent amount of ambient noise I need to overpower. Thanks.
1 Answers
Hi Mike: Whether you run these speakers together out of a single set of outputs (either A or B) or run each pair of speakers off it's own set of outputs (one pair to A and second pair to B) they are in parallel and when playing both pairs will be closer to a 4 ohm load and draw more current. You also have the flexibility to drive one pair at at time or both together. You will have plenty of output either way. Good choices TL/3981

at my bar, is it possible to have one input source ; a juke box and the second input source ; the output from from my dj equipment, output to4 speakers on my patio
1 Answers
Hi Anthony: It is true the AMP 200 features automatic source switching so you can hook up two sources but you are limited to listening to only one at a time. Not sure that will work for you application. Another idea is to purchase two AMP 200, one for the Jukebox and a second one for the DJ Mixer. Then add a SSVC4 which is a dual source four zone speaker selector with internal Impedance matching volume control with independent A or B source switch per zone. You could configure the SSVC4 to power 3 pair of speakers in the bar and on the outdoor area drive the two pair of speakers of a single zone of the speaker selector. You could add your TV audio as a second source to the First amp with the Jukebox. Now you could play either your Jukebox or TV output inside the bar while your band plays outside. You could even pipe in the band throughout the bar as well as outside at the same time. Our SSVC4 is popular for bars where everything is controlled in central location (typically behind the bar). I would be more than happy to provide a wiring diagram if this sounds like something that might work for you. Feel free to contact me at TL/3973

HI Dana: The Bridged mode only utilizes the single Speaker A Left and Right Positive outputs. The only way you could use the Bridged output is to wire the two 4 ohm speakers in parallel the amp should see an 8 ohm signal but get three times the output of the stereo 8 ohm output. TL/3967

I am trying to determine whether this amp will be sufficient paired an OSD SSVC6-D 6-Zone Speaker Selector feeding four (2 pair) Yamaha NS-IW280CWH 6.5" 3-Way In-Ceiling Speakers, four NS-AW150WH 2-Way Indoor/Outdoor Speakers and two Yamaha NS-ICS600 60w+60w RMS Speakers? Or do I need the amp 300?
1 Answers
Hi Steve: The AMP200 would be good, but the AMP300 would be better. You have 2 in-ceiling pairs both 8 ohm, a pair of Outdoor patio speakers rated at 6 ohm and two single stereo in-ceiling 8 ohm speakers. The 6 ohm speakers count as 1.5 8 ohm speakers when calculating the Impedance settings. So you would be at 7X or set to 8x to be on the safe side but with the AMP200 and even better AMP300 you keep the internal (default settings on the SSVC6D ) to 4X. That way you would run closer to a 4 ohm load and get much more output on the AMP300. Good choices... TL/3939

April 30, 2016
I need to power a total of 4 Klipsch AW-650 speakers that are mounted at a high school baseball field (big space and need clarity at high volume). We only need to handle 2 inputs: a microphone to introduce the team and an iPod to play specific music. Can you recommend an amplifier with enough power to maximize the speaker sound - but as simple as possible to switch between the 2 inputs (AMP200?). Whichever you recommend, would you please also include the preferred settings to maximize performance of the two inputs. Thank you.
1 Answers
HI The AMP 200 is a great choice for your application. It features Priority Source switching between two inputs. I am assuming you have the microphone with a transmitter with RCA outputs so you can connect directly to the Input #1 of the AMP200. Then connect the IPod to Input #2. When Input 1 is activated like when you key the mike it comes on instantly cutting off Input 2. Input 2 has a delay before it comes back on (adjustable from 3 to 15 seconds). In this case I would think you would want the delay set to the max 15 seconds to avoid it switching back to input 2 prematurely. You would connect a pair of the Klipsch 650 to Speaker A and the second pair to Speaker B. This is a True Audiophile High Current amplifier with plenty of output and great sound. And you will have great match for your Klipsch Speakers. Check to see what your connections are on the microphone. The RCA would be labeled as Unbalanced connection. TL/3851

I have a Denon AVR3808CI receiver. I have 2 ceiling speakers in another room and 4 rock speakers outside. Each pair of speakers is on a rotary volume control. The outdoor speakers are 8 ohm 175 watt max speakers. They are all connected to zone 2 but there is distortion. Will the AMP200 work for my setup?
1 Answers
Hi John: The Denon is an excellent Receiver, I am assuming you have three pair of speakers connected to Zone 2. Are they connected to the Speaker Output for the Back Surround Channels/AMP Assign? Typically Audio Video Receivers equipped with second zone output (speaker level) recommend connecting a single pair of 8 ohm speakers only. They usually discourage using multiple speakers, speaker selectors or volume controls. The receiver is using a common Power Supply for all channels driven for the custom Home theater and zone 2. This maybe causing your issue with the connection. I am also assuming you used Impedance Matching Volume Controls set to 4X? One for the internal speakers and a Volume control for each pair of rocks. Adding the AMP 200 which would connect to the Pre amp ZONE 2 output of the Receiver would be a good addition. You might also want to add an ISS4 speaker selector to organize your connections back at the AMP200. Make sure the Protection switch of the speaker selector is disabled (off) and that the Impedance matching Volume Controls are handling the protection. Check your impedance settings. With the AMP 200 you could set all three volume controls to 2X. That will show a 4 ohm load at the amplifier creating more current and audio output. Good choice TL/3847

Will this amp be able to powery two 8 ohm bookshelf speakers off channel A and one 4 ohm subwoofer bridged on channel B? If so what would be the peak/RMS wattage on channel A with stereo at 8 ohm as well would the peak/RMS wattage be on channel B with a mono bridge at 4 ohms?
1 Answers
Hi James: The AMP200 can not be configured as you propose. The Stereo/Bridge switch is either Bridged or Stereo not both at the same time, so when you select Bridged you only get one bridged output from Speaker A where you connect both positive outputs (noted as Right Positive: - and Left Positive the :+). Speaker B is not used when in Bridged Mode. You would also need to have an 8 ohm load for the Bridged mode versus the single 4 ohm sub you have (two four ohm subs in series as an example would be 8 ohm). The AMP200 would work the best if you connected two pair of 8 ohm book shelf speakers in parallel for a 4 ohm stereo load which would increase the current and output to 125 watts per channel. Then add an external Sub-woofer amplifier like our SMP-250. Make sure you connect to Input #2 then connect the Sub woofer amplifier to the Output #2 which is a direct pass through from Input #2. You would then use your controls on the sub woofer amplifier to adjust the High cut filter crossover setting and gain control for your sub woofer. TL/3816

Hello, I have the AMP200 and the SSVC6D. Do you have a simple diagram of how to hook these two up in bridge mode. I have several OSD rock speakers hooked up to the SSVC6d. Then the input coming from a Yamaha RX-A2040 receiver (zone 3 out). The instructions that are with the AMP200 are a bit confusing. Ideally can you provide a simple diagram for hooking this up. I believe there shouldn't be any issue given the equipment to run it this method.
1 Answers
Hi Steven: The bridge mode is not the way to go since it is 8 ohm sensitive. The AMP200 is a high current amplifier will provide plenty of output with the SSVC6D. It is 2 ohm stable and easily runs all day long on a 4 ohm load. And you just connect Speaker A output R and L +/- to the Source A of the SSVC6D. Make sure you connect the pre amp out from the Zone 3 to input #2. That will give you an option of running a powered sub to go with with one of your zones (output #2 only comes from input #2). Note the SSVC6D has dual source but only a master source switch so it can only play one source at a time. Note, make sure you set the gains in the back both right and left. Turn the front volume knob to full output then adjust the gains till it starts to clip then cut the gains back slightly. Do this with all the Volume controls in the SSVC6D fully open as well. You will have no problem getting the output you desire. TL/3723

How do you run this in bridge mode to your speaker switch?
1 Answers
Hi Steven: What is your application? Are you looking to bridge 2 AMP 200's and run one for Left and the other for Right channel through a Speaker Selector? Or just a single AMP200. The Bridged output is a mono two conductor connection using the two positive connection on speaker A. The input is just plus or minus to the speaker selector, and if you are connecting just a single mono connection it would be connected to only left or right input of the speaker selector. Note: in the Bridged Mono setting it is also important that the amplifier sees a 8 ohm impedance. If you can supply us with more info on your application including products you may already have or products you are looking to buy. Brand name and model numbers help.

Hi Andrew, I'm not familiar with those speakers, but assuming they're between 4-8ohms, that should be fine. Is the Polk sub a powered subwoofer or is it passive? If it's passive, it would need to have a built-in crossover to be able to run off a stereo amplifier. If it's powered, you can run it off the Line 2 output.

I want to purchase 3 sets of speakers for my back yard. A set for the back porch (14x40 feet) a set for my pergola that is about 20 feet away which is 25x25 feet and a set next to the house which as an under hang (almost cuby hole kind of feel) which houses a hot tub. I really like the size of the AP 450 speakers and want to be able to simply play either radio or an ipod or an ipad. I would like to be able to hear all of the speakers at one time or each set/zone individually say when I'm only in the hot tub and want to only hear that set playing. Can I run a single wire to each set of speakers and just bridge the next speaker (In the same set/pair) to the other speaker or would I need to actually run 6 individual wires, 2 wires per speaker pair? Can you help me with picking out the proper equipment that I need for this back yard project?
1 Answers
Hi Jeff, If you wired it as such, you would only be hearing one channel through both speakers, not stereo. So we recommend running each speaker back to the amp or to a speaker selector if you want them on different zones. I would recommend our AMP200. The AP450 are decent for small speakers, but they don't have much low end, so if you're looking for some full range speakers with decent bass response, I would go with the AP525 or AP650.

Any other setting I should change? I tried Line and Line 2 IN. Thanks.
1 Answers
Hi Carlos: The AMP200 features automatic source switching where line 1 takes priority over line 2 when it is actually playing. So when you have both Line 1 and Line 2 connected and your source connected to Line 1 is playing Line 2 is disabled. When you turn Line 1 source off Line 2 will become active. Note: there is a small knob just to the right which adjust a delay (3 to 15 seconds) between Line 1 turning off and Line 2 becoming active. Also you have Line 2 Output which is a pass through for whatever is connected to the Line 2 Input. We recommend if you connect just a single source then use Line 2. This will also allow you to connect the Line 2 output to a subwoofer to compliment the signal coming into Input #2. Regarding your setup did you make sure that the 5.1 Zone 2 actually was sending a signal to the AMP200. Sometimes the ZONE 2 output can not be digital, check your owners manual for limitations. Also try your iPod connected to both Line 1 then Line 2 to see if it works on both. Sometimes an iPod dock that is connected digitally (fiber optic or digital Coax) to the receiver will not pass a signal to the Analog output of the ZONE2. But if it is connected to the Headphone jack of the iPod then it is now an Analog signal and will play directly into the AMP200 or through the RCA line level inputs of the 5.1 receiver and then will play through the ZONE 2 output. I hope that helps TL/3223

1 Answers
Hi William Either will work if you connect the (4) 12 inch floor speakers (2 pairs) in series/parallel. These are 8 ohm speakers which is what the summed result would be by wiring them in series parallel. I will put a diagram up on the AMP200 and AMP300 showing Series parallel wiring so you can see it. Otherwise I would suggest purchasing two of the AMP200 and connect two each of the of the Cerwin Vega 12s to each in parallel (one to Speaker A and the other to Speaker B). That will probably give you more output around 4 ohm when playing both at the same time which should not be a problem for either the AMP200 or AMP300 if you wanted more power. TL/3221

Hi Shaun, First of all, great choice in an amp! The AMP200 is high-current so it will provide plenty of power to drive any outdoor speakers. The AP650s are a higher quality 6.5" patio speaker compared to the AP640. You'll have better bass response and a much crisper sound with the 650s. You can put the amp outside during use in a dry, protected area, but it can't be stored outside as it isn't built to be weather resistant or moisture resistant. The only outdoor rated amp/receiver that we offer is the MA2, but it is a low powered receiver intended to run smaller speakers. Hope that helps! Thanks. -BM 2604

I purchased 4 in-ceiling speakers along with this amp...the combination is working out very well. Only draw-back is getting the amp to turn on and off (using the "Trigger" function) is giving me some grief, but I'm determined to get it working in short order. I had an Excellent experience with Outdoor Speaker Depot. I have already recommended them to some friends and will use them when I have a future project. Quality merchandise and outstanding customer-service. Nicely done---- Steve

Very Good Product
Bought this amp to power six speakers (ACE 800 speakers), two each in the dining room, master bedroom, and outside patio when I built my whole house audio system. I have volume controls for each set of speakers. The amp has more than enough power to run the system and the speakers sound great. I have the amp hooked to zone two of my Yamaha RX-710 home theater system which allows me to listen to music in zone 2 while watching a movie over the home theater. Easy to set up, but remember that Line one feed is the priority feed when you are hooking it up as part of whole house audio. Great value. I purchased my entire system (12 speakers total)-- 6 of which were were ACE850 speakers from OSD for $2100. Similar quality elsewhere would have been nearly $5,000.

Great amp for the money
I bought this amp to replace an old Sonamp to power a three room system. For a third of the price of a new Sonamp this OSD amp does the job. I'm glad I found them online.

Very Powerful Amp and Great Sound Qualit
I was skeptical when I ran across Outdoor Speaker Depot and saw the prices for the speakers, amps and otehr components, but I needed a good outdoor sound system for a budget price. I am thrilled [...] sounds fantastic! I will definitely remember Outdoor Speaker Depot for my future needs.

This amplifier provides ...
This amplifier provides clean power at a very affordable price. I originally tried to run 3 separate pairs of 6-1/2" speakers using an old Kenwood receiver and an OSD SSVC speaker selector. Unfortunately, most lower-end amps just aren't built for powering several pairs of speakers. Sound quality was terrible and the amplifier kept cutting-out, so I realized I would have to invest in some dedicated power. I did not have the budget to spend thousands on an amplifier but I did not want to skimp on quality. The M15 does not disappoint. This unit is built like a brick house and supplies clean and ample power. I am amazed that OSD can offer such high quality at this price. I used to do all of my high-end shopping at Crutchfield, but now I'm a dedicated OSD customer. Thanks OSD!
