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.

mark mathews • 12/17/2019, 2:17:43 PM Q I tried moving to line 2 but have the same results . if I leave the front volume control at about 1/3 rd. everything seems to be ok but as soon as I move it to just under 1/2 or try to use Pandora off my direct TV there is a click in the amp and no sound at the speakers. if I turn off the amp and then turn the volume back to 1/3 rd and turn it back on it works. I always ran the front volume at least 1/2 in the past and had no problems with plenty of volume . only thing different is I am inputting from my direct TV. in the past I just listened to Pandora off my phone and everything worked great, now I cant even do that ?

A Mark, What are the master levels set to on the back of the AMP200? They should be both set to around the 12 o'clock to 3 o'clock position. If those are lower, it could just be that it's not driving the signal enough. If you can, email me some pictures of your setup at brennan@osdaudio.com. Thanks! -BM 2595
Shaun • 12/17/2019, 2:17:43 PM Q Thinking of buying this amp but I have a couple of questions, I have a decent sized pool, patio area, will this amp be better with the AP640 speakers or the AP650? I will run two pairs... Two under the deck and two by the pool. Also, can this amp be left outside as long as it stays dry. If not, do you have an amp that can do what I want and push a decent amount that can be put in a cabinet outside in a dry space? Thanks
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Shaun, First of all, great choice in an amp! The AMP200 is high-current so it will provide plenty of power to drive any outdoor speakers. The AP650s are a higher quality 6.5" patio speaker compared to the AP640. You'll have better bass response and a much crisper sound with the 650s. You can put the amp outside during use in a dry, protected area, but it can't be stored outside as it isn't built to be weather resistant or moisture resistant. The only outdoor rated amp/receiver that we offer is the MA2, but it is a low powered receiver intended to run smaller speakers. Hope that helps! Thanks. -BM 2604
Sam • 12/17/2019, 2:17:43 PM Q Trying to decide on this vs the Sherwood 5502. Looking to run 4 different rooms, each with a volume control and one set of speakers in each. Each pair of speakers is 6ohm, 80W nominal, the volume selector are 100w and you can select the impedance. Would you recommend the AMP200 even though it's only one source. And if so, any issue with the speakers? What would I set the impedance on the volume controls to? Thanks in advance, Sam

A Hi Sam, The AMP200 is a much more powerful and efficient amp than the RX5502 receiver. In terms of quality and power, this is the amp to go with. The RX5502 offers AM/FM tuning, but apart from that, the AMP200 excels in everything else. It can handle anywhere from an 8ohm load down to a 2ohm load. You can set the volume controls all to 4x. Let us know if you have any further questions. Thanks! -BM 2614
ED MARRAFFINO • 12/17/2019, 2:17:43 PM Q WHY DOESNT THE VOLUME CONTROL ON THE FRONT LOWER THE VOLUME ALL THE WAY OFF ??
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Ed, The volume knob on the front is intended to add just a slight amount of control to the master volume on the back. If you need to instantly turn the speakers off without powering the amp off, use the A & B buttons on the front of the amp. I am aware that it sounds strange to have a volume control that doesn't turn it all the way down, but that's just the design of this amp. Hope that helps! Thanks. BM 2640
Adolfo • 12/17/2019, 2:17:43 PM Q I have a working OSD-AMP200 and everything was working just fine until recently. The amp, while in normal mode, powered on blue led on. has input with playing music and senses signal on the L/R db meters (they move, as I toggle the volume higher they move higher) The problem im having is, that I have speakers connected to the speaker outputs and nothing happens, no sound, I connect them to a separate amp and they work just fine. Speakers connected to them: 4 Boston acoustics and two rock subs by osd. Pls advise,
Customer Service • 12/17/2019, 2:17:43 PM
A Hello Adolfo, It sounds like you have the "Master Level" dials on the back turned all the way off (counter clockwise). Try turning both the R and L master levels clockwise up to about the 3 or 4 o'clock position. Also make sure that the A and B buttons are pressed in on the front of the amp. Let us know if that solves your issue of no audio. Thanks! BM 2732
