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

Geoffrey • 12/17/2019, 2:17:43 PM Q Is this really a four channel amp? Can it play four different sources independently simultaneously (80x4) for bi-amplification configuration?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Geofferey: No, this is not a true four channel amplifier based upon your scenerio. It is a two channel amplifer that has a choice of A, B or A +B speaker output. The dual source feature is an automatic switching circuit. When you connect two independent sources number one takes priority when it is active. When source one is turened off source number two if active comes on after a short delay (adjustable 3 to 15 seconds). Then if you activate source number one again it comes on instanly. So you can only play one source at a time. You also have theoption to connect speaker level for one of your sources. Another key to this amplifier it is a High Current Amplifier that is 2 ohm stable. You could connect three 8 ohm speakers in parallel to one of the speaker outputs (A or B) or connect two pair of 8 ohm speakers in parallel to each speaker output (A + B). This is a true audiophile amplifier featuring a large Toridal Power Supply, ample Capacitance and large internal Heatsinks typically found on more expensive amplifiers. Add to that the unique features including the three turn on options (On, Auto/Music Sensing or 12 volt trigger) you have flexible amplifier providing great performance and value TL
Scott Culbertson • 12/17/2019, 2:17:43 PM Q How due you bridge this amp?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Scott: First you need to make sure to select Bridged Mode on the back of the amp between the Master level control knobs and 12V trigger ( bridged mode is to the right). Then you connect your Bridged output from the two positive outputs from Speaker A (the middle red binding posts). The left will be attached to the negative of your speaker and the right to the positive. it is clearly marked on the back panel above the two red binding posts; - Bridged +.This will produce 250 watts RMS into an 8 ohm load. I hope that helps TL
TImothy P • 12/17/2019, 2:17:43 PM Q I have this amp connected to 4 -8 ohm outdoor speakers (2 on Channel A and 2 on B) My question is: I have the volume control at minimum and the sound is still slightly above conversation level (more than background music). Do I need to set the master volume level on the back of the Amp to allow me to adjust the volume lower or do I need purchase an external volume control?
Customer Service • 12/17/2019, 2:17:43 PM
A Tim, I would suggest turning down the master levels on the back, this should sovle the problem. CL

Customer Service • 12/17/2019, 2:17:43 PM
A Hi Timothy, The Master Volume Control is the key. It needs to be set to an acceptable level. Set the front volume control to full gain all the way to the right. Next, adjust the Master Volume Control on the back to acceptable levels. The Volume Control on the front will operate just like a normal external Volume Control as an attenuator where you are turning the volume down and not adding gain. Good Luck! TL
