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.

129 Questions asked on 2-Channel 125W Per Channel, High Current Class A/B Stereo Amplifier Toroidal Transformers - AMP200

Dominick • 12/17/2019, 2:17:43 PM Q Can I hook this amp to the 850 rock speakers and get great sound out of the speakers
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Dominick, Yes - the AMP200 has plenty of power to run the RS850 rock speakers. There are two master level volume controls on the back of the amp which will give you a lot of power when turned up.
Kevin • 12/17/2019, 2:17:43 PM Q I've had this amp for quite some time but didn't realize until now that my receiver has a 12v trigger. I use this amp for a 4 channel zone 2 setup and only want it to come on when the zone 2 is on and broadcasting. First question is whether I need a special cable and second is do i need to leave the AMP200 on standby all the time (red)? If so what's the power consumption int that mode. I use my zone to every so often but not constantly so wouldnt want to just leave it powered "on" unless there was close to 0 draw in standby mode (red). Thanks!
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Kevin: Whether you use the Auto On Sensing or 12V Trigger you need to leave the units manual power switch to the on, stand by position. And although this is not Energy Rated unit there is a basic current draw. As far as the cable needed look for a 3.5mm male to 3.5mm male mono cable (stereo may work fine). I hope that helps Thanks for supporting OSD Audio. TL/3160
Alan • 12/17/2019, 2:17:43 PM Q I have 3- OSD 175w single ceiling speakers and 2- OSD 150w single patio speakers. I have them each on their own volume control. The stereo i have hooked to the now will shut down if I run them all. I can run the 3 ceiling speakers if the volume is set just right, but if I turn it too low or too high is shuts down. What do you suggest? Is the stereo the problem or do I have something hooked up wrong?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Alan, First you want to check your amp/receiver's ohm rating. Many receivers can only handle an 8ohm load. If that's the case, that would make sense why it's shutting off because the load of all those speakers is lower than 8ohms. Secondly, unless these are dual tweeter speakers, they shouldn't be ran individually. Most 8ohm speakers need to be run as a pair of speakers, because together they form an 8ohm load. Separately they each are 16 ohms which is not right for a volume control.
Stuart • 12/17/2019, 2:17:43 PM Q I am interested in this amp, but would like to make sure this is what I need. I am installing 4 pair of Polk Audio Atrium speakers (each 8 ohm, 80 watt). Would this amp be able to handle all 8 speakers playing at once? How would I wire this setup properly?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Stuart, Yes - this is the amp for your application. You would probably want to run a multi-zone speaker selector off this amp if you want to have on/off control for each zone or pair of speakers.
William • 12/17/2019, 2:17:43 PM Q Hello, I have 2 sets of Cerwin Vega VE12s(4 12in floor speakers) and was wondering would the OSD-Amp200 be able to power them efficiently to their fullest potential? Also what would be the difference between the OSD-Amp200 and OSD-Amp300? Which would be better for my set up? I'm running into the problem where receivers do not have enough power to power them with out shutting off.
Customer Service • 12/17/2019, 2:17:43 PM
A 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
