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. 

High Performance, High Current Power 
Rated at 80 watts per channel at 8 ohms, and stable down to 2 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 automatic circuit. 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. 

AMP200 offers 80 watts RMS per channel of power, with bridgeable outputs for up to 250 watts RMS. A, B, or A+B speaker selector switches make managing connected outputs easy. And a signal-sensing power on feature lets the amp power up automatically when you power on your source. 

Automatic Source Switching 
The AMP200 can automatically switch between connected sources, thanks to a priority signal-sensing feature. So if you have your iPod connected to input 2, then decide you want to watch a movie, when the DVD player connected to the main input 1 is turned on, the AMP120 will automatically switch to that source. 

A variable delay control lets you adjust the amount of time needed to "listen" for a signal from your main input, between 3 and 15 seconds, so things like gaps between CD tracks won't accidentally switch your inputs. 

Works with Smartphones, iPods, and Other Portable Devices 
Use the AMP200 to connect your Smartphone or other portable music device (as long as you have a headphone jack.) The AMP200 includes two RCA signal level inputs marked as red for right and white for left. Using an RCA-to-mini stereo cable (sold separately), plug the 3.5mm stereo connector into the headphone output of your iPod or other portable device, then connect the RCAs to one of the inputs of the AMP200.

James • 12/17/2019, 2:17:43 PM Q I'd like to run my one pair Boston Acoustics VR975 through this and wanted to be sure it is an appropriate match?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi James: This is a great match for your single pair of Boston Acoustics. It would even be a better choice to power two pairs of your Boston Acoustics VR975. It is a High Current Amplifier that is 2-ohm stable. Two pairs of 8-ohm speakers played at the same time in parallel creates a 4-ohm load. It features a High Power Toroidal Power Supply, all discrete components, Plenty of internal Capacitance and Ample internal Heat Sink (one of the reasons it weights 24 pounds) to help dissipate the heat generated by the higher current draw at the lower impedance demands. Think about adding our Pre-One Preamplifier to create an Integrated Amplifier package. The new Pre One has a1.5MV gain on the output plus four inputs including a dedicated Phono input with built-in Phono Pre-amp. Great choice. TL/5048
Kent Johnson • 12/17/2019, 2:17:43 PM Q Can i power 3 omni subwoofers or do they have to be in pairs of 2
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Kent: The AMP200 is a Full Range amplifier and unless you are using subs with internal crossovers it would not be the amp for you. And even if you are dealing with subs with internal crossover there are better choices especially since we added our SMP500DSP sub amplifier. But typically you can connect two 8 ohm subs in parallel and see a 4-ohm load which the new SMP500 will handle. The real key is to take the SMP500DSP and connect 4 each of OMNI subs in Series-Parallel so the Amp sees a nominal 8 ohm but has the horsepower to run all four speakers. I believe we are even adding an SMP1000. So no on the AMP200 and possibly on the SMP500DSP either for 2 or 4 subs. We ran 8 subs off the SMP500 last year running in groups of 4 in series-parallel for two 8 ohm sets then in parallel, so we had a 4-ohm output. We called it the wall of Bass so I know it can be done.

Joe Rizzuto • 12/17/2019, 2:17:43 PM Q I'm looking to upgrade my outdoor sound system.I would like to purchase your AMP200 and want to make sure i'm pairing it with the right speakers. i will be using mostly an IPAD OR IPHONE to stream music. i wpould like to use your AP850 OUTDOOR PATIO SPEAKERS, i pair of them for now maybe 2 pair later on in the back of my yard about 30 ft away. Currently on my deck i have a pair of 61/2 in. outdoor speaakers 150 watt 4 ohm. and connected to those a small pair of 40 watt 4 ohm speakers fora suround sound effect(.If those are too small i can get larger ones). Will this configuration be ok? And the best way to hook them up. can i use A for the deck and B for the yard.also i would like to have the ability to raise the volume in the yard and have it lower on the deck can you recommend an outdoor volume control that will work for me, and the recommended guage of speaker wire i should use. thanks!

A Hi Joe: The AMP200 is an excellent choice to drive the pair of AP850 (speaker A) and you can connect the Speaker B to your other pair of speakers with the odd second pair for the surround. The three pairs will generate a 2.6-ohm load which is good for the AMP200 since additional power output is a good idea. Also, check out the Pre One preamplifier which will give you front-end controls and up to four inputs. Plus 1.5V increase to the AMP200 is ideal for getting more power from the AMP200. It also adds a Base, Treble, Mid, and Loudness control knobs. Also, think about adding volume controls and speaker selector if you expand beyond the three pairs. You will have plenty of power to grow your system with the AMP200/Pre-One combination. TL/5195
Luis • 12/17/2019, 2:17:43 PM Q Hello, I purchased a model house that came with 6 ceiling speakers and 3 wall volume controls, as they had ambient sound in 3 places. I would like to understand what I need to make it it all work, receiver, or anything else. Thank you,
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Luis: The AMP200 is a good start, then add the DSM4, 4 zone Speaker Selector and last but not least the Pre One Preamplifier. Start by connecting your first volume control related to the first pair of speakers to area one. The second volume control and the second pair of speakers connected to zone two and then the last volume control and third pair of speakers connected to area three of the DSM4. Now connect the AMP200's Speaker A to Source A of the DSM4 Speaker Selector. I am assuming that you have Impedance Matching Volume Controls that will handle your protection. If so, you will need to make sure that the Protection switch on the back panel of the DSM4 is disabled/turned off. The last component, the Pre One, Preamplifier is a perfect addition to the AMP200 providing the front end control including master volume, bass, mid and treble control knobs. It also has four source inputs including one for phono and features a 1.5Volt output. There are multiple source options you can select to connect to the pre one including Alexa, Google Chrome Cast or even SONOS Connect. The Pre One uses an RCA patch cord to connect to the AMP200 (line 2 input). Please contact me if you need additional clarification, timleahyor@gmail.com. Note: The DSM4 includes an additional zone for you to expand to four zones. You would need to add a fourth Impedance Matching Volume Control as well. TL/5199
TC • 12/17/2019, 2:17:43 PM Q Hello there. I'm getting my backyard completely redone and looking to run 3-4 pairs of Kicker KB6000 8ohm 75rms150peak(Was looking at the AP525 to). I was thinking of using this amp and a SSVC4 or 6 to control the volumes to each area. Example being the patio speakers being louder than the pool area. Would something like this work? If not, what else would you suggest. I wouldn't mind some bass either without breaking the bank, but I know that can be tricky outside. Thanks!
Customer Service • 12/17/2019, 2:17:43 PM
A HI TC: The AMP200 is the number one choice for your application. You can not go wrong with either the Kenwood Speakers or the AP525. But check out the AP650 with the 6.5" woofer like the Kenwood KB600. Note both the AP525 and AP650 feature a unique mounting bracket that both swivels and tilts for more install flexibility. Also, note the frequency response for both the OSD AP speakers goes lower than the KB600. Both the AP525 and AP650 feature our highest rated outdoor cabinet with an IP6X (100% sealed from Dust). Regarding the SSVC4/6 with built-in Impedance Matching Volume Controls the difference is the SSVC4 has Dual source with individual dual source A/B switch per zone. The SSVC6P has a dual source as well but has a master A/B switch so you can either play only all speaker A or all speaker B. Not sure if the dual zone is all that important or having 6 zones versus 4 is the key (note adding a second zone also means adding a second amp). The other alternative to the SSVC4/6 is the DSM4/6 speaker selector along with external OVC300 outdoor Impedance matching Volume Controls. Some people like having a volume control located near each pair of speakers they will control. Lastly, regarding potential subwoofer(s) check out the new SMP500 and GLS8 in ground sub. You could start with one GLS8 to see if that is enough coverage. The SMP500 will drive two GLS8 (a 4-ohm load when wired in parallel). Please let me know what you think; I can provide you with a wiring diagram if needed. tim@osdaudio.com. TL/5205
