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.

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!

A HI TC: One other note regarding the AMP200. You should also consider adding our OSD Pre-One Preamplifier. It is the perfect addition to the AMP200. It features four selectable inputs, control knobs for Bass, Mid, Treble, and Loudness. Plus Mono and low-frequency knobs. But the real key is the 1.5V output gain controlled by the Master Volume Control. TL/5205
Harry Savage • 12/17/2019, 2:17:43 PM Q Help please ! I have a boat house approximately 5,000 sq. ft. in size. Basically, this is a large covered deck over water. I am using a Denon AVR 1802 to power 4 Klipsch speakers, 50 watt each at 8 0hms. We mostly use an ipod , sometimes the radio. I am up grading to 4 Klipsch AW-650's at 85 watts each for the main listening area, and moving the 4 smaller Klipsch speakers around. I am also adding a svs 2000 subwoofer or Klipsch equal . I would also like to up grade the receiver. What would you recommend to drive all these speakers and sub? would like the 4 650's on one volume control and the smaller ones paired up on different volume controls. Any recommendations on subs, sources and wiring diagrams appreciated.

A Hi Harold: The ideal components for your system would include the following: Preamp-1; preamplifier, XMP300; power amplifier and SSVC4; 4 zone speaker selector. I have sent info and system wiring diagram directly to your email address from tim@osdaudio.com. Please review and let me know what you think. TL/5220
Alan • 12/17/2019, 2:17:43 PM Q Hello! Is it possible to bridge Speaker A (8 ohm load) and at the same time play throught Speaker B output with a 4 ohm load? The house had pre-installed speakers in two contiguous zones: 4 speakers on one zone (wired for 8 ohms) and two speakers on the other zone (4 ohm load).
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Alan: Part one of your question: You can only Bridge Speaker A output only, Speaker B is not available. You can use Speaker A and B together if connected in stereo. Now regarding your application, I am assuming you have two pairs of 4-ohm speakers wired in series(for an 8-ohm load) and that you have another pair of 4-ohm speakers playing off the speaker B. The AMP 200 will allow you play this configuration, The AMP200 is stable down to 2-ohm. I believe the amp would see a 2.6-ohm load. Which would draw plenty of current from the amp when playing both A and B together (in a parallel connection). Even better going with the AMP300. "Scotty, I need more Power." TL/5389
Kevin • 12/17/2019, 2:17:43 PM Q a couple of years ago I purchased two OS790 Omni Directional speakers and hooked them directly to my Yamaha receiver.  They barely produced and sound, I'm guessing because they were underpowered.  Is the AMP 200 a good amp to power my two OS790 speakers as well as two AP650 patio speakers for my backyard pool area?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Kevin:I am curious, when you mention connecting directly to your Yamaha Receiver, was the Yamaha a Home Theater Receiver? What is the model number of the Yamaha and were you connected to a Zone 2 output or channels 6 and 7 of a 7.2 Receiver? The AMP200 will definitely help with your output especially if you add the AP650 to Speaker B. The two pair wired in Parallel (one pair to speaker A and the other pair to Speaker B) will create a 4-ohm load and increase the current draw and double the output of the amplifier.Good choice: tim@osdaudio.com.
