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

ray • 12/17/2019, 2:17:43 PM Q When using this to power multiple pairs of speakers through a speaker selector, do you just use the speaker A outputs? In that scenario, how much power is actually getting to each speaker (assume 4 pairs of 8 ohm speakers) ??
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Ray: Yes you would connect to either speaker A or Speaker B. In some cases you could connect the speaker selector (depending on the speaker selector and how it is configured) to Speaker A and still connect a single pair the Speaker B. Regarding the question of output per channel there are several factors involved to determine what that would be. What Speaker Selector you are using, Are you using Impedance matching Volume Controls either internal or external or are you using a simple Speaker Selector like our IS4 with internal protection. I do think the AMP200 will have plenty of output for most anything you can connect to it. And if you think you might still need more then go with the AMP300. TL/4484

A I'm using a simple speaker selector with internal protection, no volume controls.
Joe Lepera • 12/17/2019, 2:17:43 PM Q I bought 4 of your rock speakers (RS670) rated for 150W max at 8 ohms. Can this unit run all 4 seamlessly?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Joe: This is a great choice for both Amplifier and Speakers. Run one pair off speaker A and the second pair of Speaker B. No problem running both at the same time. Amp is 2 ohm stable. You could easily run three pair at once. TL/4565
Rob S. • 12/17/2019, 2:17:43 PM Q Hi. I have pre-wired my house for 8 zones. 6 regular stereo zones. 2 of the zones are actually split, one speaker to a bathroom, the other to one of the kid's bedrooms, this times 2. I hope that wasn't a bad idea. Each zone has wiring for a volume control. All leading back to the laundry room where I will have the equipment. So, is the AMP200 a good choice? Would AMP120 be underpowered? While I have you, would the DSM8 be a good speaker selector choice? My source A will be an Amazon Dot. My source B will come from the living room stereo to hear the TV, Turntable etc. As far as volume controls, is the VMS60 okay or do I need the VMS100? For speakers I was looking at the ACE600. I don't want them too huge, but I want them to sound decent, but audiophile isn't necessary. Thanks in advance.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Rob: The AMP200 would be a minimum that you would want for your setup. And to do two source properly you would need 2 of them but you can start with a single amp to start with but would be limited to listening to either the Dot or the equipment from the Living room Receiver. The AMP200 features automatic source switching between two sources with input #1 taking priority over line 2 input. The DSM8 features Dual Source (dual Amp) switchable per zone (A or B). Always go with the biggest Impedance matching Volume Control so either the VMS100 or even VMS300. So lastly, are you saying you actually have six zones with two of the zones splitting between two rooms? Did you run four conductor to each (I hope) and not 2 conductor to each so right channel to the bathroom and left channel to the kids room as an example; please confirm? You may be able to go with the DSM6 versus the DSM8. Look at the ACE640 over the ACE600, a little better components and a true second order crossover. For the bathrooms take a look at the ICE800TTWRS ( a weatherproof speaker) or the MK690TT (which trim-less design would match the ACE640). let me know if I can be of further assistance... tim@osdaudio.com TL/4611
