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

Joe • 12/17/2019, 2:17:43 PM Q Are any of the amps (200, 300) or speaker selectors, 19" rack mountable?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Joe, We currently do not offer any optional rack ears. Our amplifiers do not have the pre-drilled cut out holes you would need. There are a number of universal rack mount shelves available; check out the following link: http://www.twacomm.com/catalog/dept_id_732.htm?sid=CFC94DBEDC70496F48D88E8C893073FA The OSD AMP7 Speaker Selector has the holes but no brackets are available. The link may also address universal rack ears. TL/MA
Judd • 12/17/2019, 2:17:43 PM Q I just connected this AMP to a SONOS Connect and set the amp up for "Auto Sense" mode. The music plays fine but when I stop the music or even remove the RCA source cables all together the AMP never goes to standby. Does anyone have an idea as to why?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Judd, Here’s what’s happening. When you switch between 12-volt trigger (and it goes instantly to red, stand-by mode) then auto sensing and power on to blue, you will hear the amp click internally. This is normal operation. The 12 volt is a hard-wired trigger so it instantly goes to stand by. The way the auto sensing works is that it takes between 6 to 15 minutes to go to stand by; otherwise, you might have the amp constantly going back and forth between On and Standby, depending on the music. If you were listening to classical music, it might click on and off several times. Try it again but see how long it takes your unit to go into standby. Our AMP200 on the test bench took exactly six and a half minutes. TL/MA
Wojtek • 12/17/2019, 2:17:43 PM Q Is this amp powerful enough to power 8 pairs of speakers with volume controls connected to speaker selector?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Wojtek, There should be no problem. Just use impedance-matching volume controls. We also recommend using our DSM8 and disabling the protection circuit of the speaker selector. Make sure you set the volume controls to 8X. You can also set them to 4X for more power out of the AMP200. You could even utilize two DSM4 speaker selectors (again defeat protection). Connect one DSM4 to Speaker A and the second DSM4 to Speaker B. Be sure you set impedance-matching for all volume controls settings to 4X. TL/MA 1261
ChrisJ • 12/17/2019, 2:17:43 PM Q I am really interested in this amp but am confused. I have three pairs of Polk Patio 25 speakers that are 8 Ohms and 150W that I would like to power with this amp. All six speakers will be on at the same time. Can this amp effectively power these 6 speakers or do I need an amp with more channels? If so, how do I need to wire the speakers and is there any other equipment that I need?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Chris, This amplifier will have no problem driving three pair of speakers. We suggest connecting two pair to Speaker A output (in Parallel, Positives to Positives and Negatives to Negatives) and the third pair to Speaker B. With only Speaker A playing, the two pairs in parallel will create a 4-ohm load and increase the output of the amplifier from 85 watts a channel to 125 Watts a channel because the load increases the current demand. Add the third pair of speakers to Speaker B and play both at the same time and you increase the current demand some more. This High Current Amplifier features a large Toroidal Power Supply, ample internal capacitance, all discrete components and a large internal heat-sink to handle the increased current demand from the 4- to 2-ohm load. It will also provide audiophile sound quality when using all discrete components in the audio section. There is a reason why this amplifier weights and costs almost three times as much as a chip amplifier. Other features include Automatic Source Switching, separate Right and Left Master Gain controls and three options for turn on (ON, Auto Sensing or 12-volt trigger). You will not be disappointed with this amplifier; it is a great choice! TL/MA -1401
John • 12/17/2019, 2:17:43 PM Q I have 2 pairs of outdoor speakers and a pair of indoor speakers with built-in amp. Could this AMP200 meet my needs by powering my outdoor speakers and also hooking up my amplified indoor speakers too? Any suggestions? Any help would be appreciated.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi John, You will have no problem running the AMP200 to power two pairs of outdoor speakers. These would be connected to Speaker A with speaker wire. The second hookup for the powered speakers would come from the Line 2 Output and connected with a pair of Stereo RCA cables. Make sure you use Line 2 Input for your Source connection. Line 2 output is limited to the information that comes in to Line 2. If you were to connect a second source to Line 1, it would not play in your powered speakers. TL/MA- 1403
