Lifetime Tech Support

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.

Gene • 12/17/2019, 2:17:43 PM Q I am thinking of purchasing the rsub300 and smp250 combo along with two pairs of rs790's and the amp200. I already have two Polk sat 30's and would also like to get a speaker selector with volume control but as you know, OSD is out of stock so I will have to go elsewhere for that one component, but could you please tell me how I would wire all of these together and do I need anything else to listen to iPod/iPad libraries in my back yard? Thanks in advance for any help you may be able to provide.

A Hi Gene: Sometimes depending on your application it is better to run our DSM4 Speaker Selector (Dual Source like SSVC series except no internal Volume Controls) and use dedicated external Outdoor Impedance Matching Volume controls located near each of you stereo pair of speakers. It is also easier to run a four conductor (in a single jacket) cable from your AMP200 to the Speaker Selector then out to the OVC300 Volume Control from the DSM4. Then run two conductor to each speaker from the Volume Control. It is better to let the Volume Controls do the impedance matching making sure to disable protection on speaker selector. Let us know what you think. TL
Carlos • 12/17/2019, 2:17:43 PM Q Hello , I´ve ten ceiling speakers to be used in three zones ( 2 , 6 , 2 ) and one source . What´s the best amp option to use .
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Carlos, This is an excellent amplifier for whatever application you have in 8 ohm. Are you saying 10 speakers or 5 pairs? Two zones with a pair each and one room with three stereo pairs? If so, the DSM6 six zone speaker selector would work best for this application. Will you be using volume controls for your system? Just a little more info and we can address your application. TL/MA
Ricardo • 12/17/2019, 2:17:43 PM Q 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!
Customer Service • 12/17/2019, 2:17:43 PM
A 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. TL/MA
Ian • 12/17/2019, 2:17:43 PM Q 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?
Customer Service • 12/17/2019, 2:17:43 PM
A 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. TL
Val • 12/17/2019, 2:17:43 PM Q Would this amp work to run 4 outdoor Bose 251 speakers?
Customer Service • 12/17/2019, 2:17:43 PM
A 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. TL/MA
