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.

What's on your mind?

Andrew Tomsik • 12/17/2019, 2:17:43 PM Hi. Would this amplifier have enough power to run 1 pair of Electro-voice EVID 6.2 speakers and 1 Polk Audio Atrium 10 Subwoofer? How would you run the setup? Can this 3 speaker setup be controlled with the OVC300 Volume Control? Thanks,
Customer Service • 12/17/2019, 2:17:43 PM
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.
Bryan Capener • 12/17/2019, 2:17:43 PM 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
Customer Service • 12/17/2019, 2:17:43 PM
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
dana • 12/17/2019, 2:17:43 PM bought this amp, have had it 3 days, i keep having signal issues, amp keeps clicking on and off im only using 1 source, not sure whats wrong, help please??
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dana; What source are you connecting to the AMP and which input are you using? Typically we recommend using input #2 when connecting a single source. The input #2 is tied in with Output #2 as well if you wanted to connect a powered sub woofer. Sorry to hear you are having problems, let's see if we can solve this... TL/3672
Joe • 12/17/2019, 2:17:43 PM 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?
Customer Service • 12/17/2019, 2:17:43 PM
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
Dewayne Bruce • 12/17/2019, 2:17:43 PM Hello. I'm looking to purchase an amp to power 4 pairs of speakers all hooked up as one zone in my home. I have 3 pairs of Sonance VP60R (100W max/8ohm nominal/6ohm minimal) and 1 pair of Sonance 51 Mariner exterior speakers (60W max/8ohm nominal/6ohm minimal). Each pair has a Sonance VC60SIM sliding volume control. I saw the price tag of their 2-100 Sonamp and started shopping around. The AMP200 looks pretty comparable in specs, but I am fairly ignorant of the nuances of home audio. Will the AMP200 perform well with this setup? Thank you!
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dewayne, Depending on how exactly you have your speakers wired up, the amp200 would be a good amp to go with. I would suggest wiring 2 pairs of speakers to each channel A and B of the amp200. If you wire them in parallel(stacking them on the channel) that would show the amp a 4 ohm load which the amp200 could definitely handle. CS 3710
