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.

QUESTIONS & ANSWERS

By Ronnie from Tennessee on May 1, 2012
Does this amp have auto on/off when it senses input. Want to place inside, but run outside speakers (4 bose freespace 51) with a marine cd/tuner I already have by pool? Would like to use oudoor volume control switch with setup also.
By Customer Service - Q&A on May 2, 2012

Answer:
Hi Ronnie:

This amp features three turn on options, Manual on/off, Music sensing for auto on/off or a 12 volt trigger that can be hardwired from a receiver that features a 12 volt trigger as well. It will work great with a couple of Volume Controls. Check out our OVC300 (white or Grey) outdoor volume controls. We also sell the CL3 rated speaker wire in 16 and 14 gauge 2 or 4 conductor in 50 and 100 foot cuts ups. Wire is ok for direct burial as well.

How due you bridge this amp?
By Customer Service - Q&A on March 8, 2012

Answer:
HI Scott:

First you need to make sure to select Bridged Mode on the back of the amp between the Master level control knobs and 12V trigger ( bridged mode is to the right). Then you connect your Bridged output from the two positive outputs from Speaker A (the middle red binding posts). The left will be attached to the negative of your speaker and the right to the positive. it is clearly marked on the back panel above the two red binding posts; - Bridged +.This will produce 250 watts RMS into an 8 ohm load.

I hope that helps

By Yash from Toronto, Onatrio on May 1, 2012
HI,
I have 4 ceiling speakers, one sub and only one source. How can I use this device?
Thanks
By Customer Service - Q&A on May 3, 2012

Answer:
Hi Yash:

Based upon your description, the AMP200 is perfect for your application assuming that you have four speakers or two stereo pairs and a powered Sub-woofer and one source. The ceiling speakers can be connected in a couple of ways, first one pair to Speaker A output and the second pair to speaker B output from the AMP200. Then you connect your one source to input number 2. Next, connect the powered Sub-woofer to the pre-amp Output from source 2. This is the ideal setup assuming you are connecting to a Powered Sub woofer. You also have the option of connecting both the pairs of speakers to Speaker A output then connecting your Powered sub-woofer to Speaker B output. In this configuration the sub-woofer would operate when either source was being played. The only downside to connecting the Sub-woofer to the Source 2 output it is only will be active when you use source #2. The sub would not play when Source 1 is playing. This amplifier not only has plenty of power but has lots of flexibility. So I need to know if I have described your setup or is it different in anyway. Please let me know either way.

Will this be able to run RSUB300 (HF26) UltraPro Dual Woofer Rock Subwoofer and two RS680 Ultra Sound 6.5" Rock Speakers (HF12) at the same time? Also it looks like you can plug your iPod straight into it would that mean i wouldn't need a stereo receiver?
By Customer Service - Q&A on May 5, 2012

Answer:
Hi Connor:
You would need to add a dedicated sub-woofer amplifier like our SMP250 with an internal crossover built in to drive the RSUB300. We have a great bundle featuring the RSUB300 and SMP250 combination. The AMP200 would be perfect to drive your two pair of RS680 Rock speakers while allowing you to plug your iPod or laptop with your iTunes library and streaming internet capability directly into the AMP200 as your sources. There are a couple of choices to connect this all together. We would be happy to assist you further if you choose to go OSD branded products. We have the CL3 Direct Burial Speaker Wire along with our Aqua Blue Direct Burial connectors that will help complete the job as well.

By paul from aberdeen SD on January 27, 2013
Does this have to be used as a whole home audio system, or can i hook it up to my TV and use it for a home theater system?
By Customer Service - Q&A on January 28, 2013

Answer:
Hi Paul,

You should be looking at a basic 5.1 surround sound system receiver. The AMP200 is 2 channel amplifier that you would use if you picked out a AV receiver with a second zone output with the intention of expanding your system to multiple zones while using the AV receiver for your central source.

By Ricardo from Torreon, Mexico on July 9, 2012
I have 3 pairs of AP670 speakers, I want to know if I can use this amp to power them up... If so, I want to know what type of wiring would you recommend (parallel, series, etc.) to connect the 6 speakers to the amp? And also, how would I connect a speaker selector to work with this amp?
Thanks for your help!
By Customer Service - Q&A on July 9, 2012

Answer:
Hi Ricardo,
If you wire all three speakers in parallel, whether you use a speaker selector like our DSM4 or just directly to speaker Output A, you will get a 2.6 ohm load (with protection switch disabled on the DSM4). When the impedance drops that low and you have all three speakers playing at a high volume level, there is an increased demand in current in order to meet the extreme load. A direct result of this demand is an exponential increase in heat. The AMP200 has very large toroidal power supply and 8 high output truly linear bipolar output devices mounted to a large internal heats ink (the amp is 24 pounds) that allow it to handle 2-ohms loads. Another result of the low impedance is also an increase in power from 4 ohm 125 Watts to 2 ohm at 200 Watts. Add this to all discrete components in the Triple Darlington audio section and you’ll get true audiophile sound quality.

By Ian from NJ on July 11, 2012
I have an outdoor set-up with two Niles RS 8 speakers configured in single speaker stereo mode (i.e. both left and right speakers are wired to same physical speaker). Wired this way these speakers require outputs A and B to run together and will draw 4 ohm's. Recommended power is 50-200 watts.

The inputs to the amplifier would be from an iPod and a Satellite Radio. Seems this amp does not have tone controls though bit would otherwise fit the bill? The amp would be located in a covered location outdoors. Would this amp be a good choice and, if not, do you have another that would be a better fit?
By Customer Service - Q&A on July 16, 2012

Answer:
Hi Lan:

The AMP200 will handle any load you throw at it. Based upon the manual from Niles theRS8s are 8 Ohm speakers when connecting both Voice Coils of the single stereo speaker. You would not have a problem connecting both speakers one to A and the other to B. You could even wire both to A or B in Parallel. You would connect your Satellite radio to Line 1 and the iPod to line 2 input. This amplifier is a hybrid Amplifier that has the automatic source switching and Master gain control and a volume knob that works like a volume control. It does not have separate bass and treble. The iPod has settings for both Bass and treble and I am assuming your have settings available on your satellite Radio as well. Your master volume level should be controlled by the iPod and satellite radio.

By Geoffrey from Texas on January 21, 2012
Is this really a four channel amp? Can it play four different sources independently simultaneously (80x4) for bi-amplification configuration?
By Customer Service - Q&A on January 22, 2012

Answer:
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

By Val from NY NY on July 16, 2012
Would this amp work to run 4 outdoor Bose 251 speakers?
By Customer Service - Q&A on July 17, 2012

Answer:
Hi Val,

Yes, the AMP200 would be able to power your two pair of BOSE 251 speakers. The owner's manual rates the speakers at 6 ohm and states they will work with either a 4 or 8-ohm amplifier. If you are just powering these two pair of speakers, connect one pair to Speaker A and the second pair to Speaker B. The AMP200 is a High Current Amplifier that will have no problem supplying plenty of power to drive the BOSE to their fullest potential. We would also recommend using our OSD CL3-rated 14/2 (2 Conductor 14 gauge) Speaker Wire to get the most current to the speakers.

By Gary from Atlanta, GA on May 22, 2012
Hello,

I currently have a pair of Atrium 45s powered by a Sony receiver. I'd like to add two RS850TT and two AP550TT powered by the AMP200. Will this amp be sufficient for the 4 speakers?
Also, what volume control would I use to control the volume of the two sets separately?
I'm guessing I'd have to use the speaker in to control the master volume with the sony receiver?
Thanks

By Customer Service - Q&A on May 22, 2012

Answer:
Gary,
I would go with our AMP300 because you have 5 pairs, (each single stereo counts as two) You can use our ISS6 with our OVC300's for volume controls. The speaker selector might be sold out, so you can use our DSM6, or if you wanted the volume controls on the speaker selector rather than going with the OVC100 just get the SSVC6. Take a look at those- If you have further questions give us a call- 1.888.779.4968

By Customer Service - Q&A on May 22, 2012

Answer:
Hi Gary,

The AMP200 should have no problem powering the four OSD stereo speakers. I suggest using two of the OVC300 outdoor impedance matching volume controls and connecting one of the OVC300s to control two of the RS850TTs. This would be connected to Speaker Output A of the AMP200. The second OVC300 volume control would connect to the two AP550TTs to Speaker Output B. Make sure to set the impedance matching setting to 4X on both of the OVC300 volume controls. Be sure to set the master gains on the back of the AMP200, while you have the volume knob on the front of the unit, to max or all the way clockwise (making sure your receiver master volume is at your peak acceptable levels). Also make sure your OVC300 volume controls are set to full volume (all the way clockwise). Adjust the right and left gains until the sound starts to clip or distort. Now turn it back slightly. Your volume levels will be set so now the master volume knob (or remote) on the receiver controls the overall volume. The AMP200 is a real workhorse and a true high current amplifier with audiophile sound quality. I am also a big fan of our stereo speakers for outdoor applications. Great choices, we also have CL-3 rated speaker wire (16 or 14 gauge in two and four conductor versions) and our unique Aqua Blue connectors which are all rated for direct burial as well. Thank you for considering OSD branded products.

Replacement Amplifier
March 24, 2013
I replaced a stereo system which powered two speaker systems with this amp and now use an Airport Express to feed the system rather than an iPod and other components. This allowed me to place the system out of sight in a closet and control it remotely with Air Play along with other Air Express systems in our home. I appreciated the information found on OSD's web site as it allowed me to know all the features of this amp as I was making my selection. Having the owners manual available online prior to purchase was also appreciated. Order processing and shipment were prompt and the amp arrived on time and very well packaged. The installation went smoothly and the features preformed as stated in the product description and manual.
Pros:
Signal sensing on/off. Low power use in standby. Well built. Quick easy setup. More than enough power. Great sound. Features for price.
Cons:
No dislikes at this time.

OSD-AMP200
June 3, 2013
This AMP has plenty of power. My only complaint is after setting the maximum volume you want in the back of the receiver when you turn the volume control switch all the way down, it is still playing fairly loud. Would like to be able to turn it down further, however if you adjust it in the back to do that, then the max volume it not hi enough for my taste. Solution was to find a happy medium and deal with it. Besides that it's a very nice well built amp.
Pros:
Plenty of power to handle multiple room speakers.
Cons:
Volume issue with the adjustments from front controler to back controler.
Best Uses:
Pre amp out.

Solid amp
March 22, 2013
The speaker selectors buttons on the first AMP200 I received did not make solid connections, so I had to return it. OSD was great in handling the return and getting a replacement amplifier out to me. The second one worked perfectly. Running 4 OSD ICE800WRS speakers (for my covered patio) from this amp and with the master volume at ~20%, I am still blowing out my eardrums. This unit has plenty of reserve power!
Pros:
Solid, high output, clean sound
Cons:
The first unit received was not perfect...

An excellent and capable amp!
December 30, 2012
I bought the OSD AMP200 to use as a zone 2 amp to power 3 pairs of OSD speakers - 2 pairs on outdoor patios and 1 pair inside. The amp is very easy to set up and easy to use. The construction is very solid with a good quality feel to it. The amp delivers great sound to all the speakers simultaneously and it never gets hot and doesn't cut out even after hours of continuous use. It seems capable of powering additional speakers without difficulty. My only minor gripe about the amp is that it lacks remote control, but I knew that before buying it. Ordering online was easy. It arrived promptly and very well packaged. OSD has great customer service. This is the second time I have bought from OSD. My previous purchace was speakers and in-wall volume controls. This time around, my personal contact at OSD was Brennan. He knows his stuff and has been very prompt with answers to my queries. Thank you Brennan!
Pros:
Great Power To 6 Speakers, Never Gets Hot, Great Sound Quality, Setup Is A Breeze, Energy Efficient, Good Clean Sound Output, Easy To Set Up, Good Power Output, Accurate Controls
Cons:
none so far

Love the amp...would recommend to others for sure. Nice clean power for our out-door patio cover (extended our "roof-line" out to cover our patio). 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.

Very Good Product
June 16, 2012
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.

This amplifier provides ...
January 22, 2010
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!
