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

Kevin • 12/17/2019, 2:17:43 PM Q I am interested in the amp300 to power 6-7 pairs of whole house audio. I am currently powering this set-up with an older Harmon Kardon av receiver through an Osd 7 channel speaker selector. All is controlled by my iPhone. This receiver does not accommodate an external amp, and I would like to add more power as I have some longer runs outside. I also don't want to lose the iPhone controllability. I only need stereo. Can you recommend a set-up? Do I need to purchase a new receiver to use the amp300? If so, which do you carry for this application? I have been happy with your products. I am also running your 200 watt mono amp to a passive outdoor sub on this system and two powered subs y-d. Thank you, Kevin

A Hi Kevin, Thanks for contacting us. Those are all good questions. First off, are you 100% sure that your current AV receiver will not allow you to run RCA out into an external amp? The output doesn't necessarily have to say "pre amp out", but can simply be an "output" as long as it's RCA (red/white). If it is an older model receiver, then I understand it may not have that capability. If not, and you definitely want to run your receiver as a music source to the amp, then yes, you would need to upgrade to a more modern receiver with an output. As for the amp - I would recommend running our AMP300 to the ATM-7 selector that you currently own. This will provide enough power to run that many zones at once. Even without a receiver, you can still run any source to the AMP300 via RCA, even an iPhone or any kind of mobile device. The AMP300 also has a line output that would allow you to connect your mono subwoofer amp to it, sending the audio through to your subwoofer. I hope that answers most of your questions, but if you have any more, feel free to call us or reply back. Thanks! -BM 2397
Larry • 12/17/2019, 2:17:43 PM Q I would like to use either this amp or find one that will work to power 2x Yamaha NS-AW294 speakers, 2x OSD RS840 Speakers and 2x OSD ON-SUB200 sub's all running at the same time. Would this unit work? If not what are my options? Thank You for your time..
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Larry, Thanks for the question. Yes, the AMP200 is usually recommended for running no more than 4-5 pairs of speakers. In your case, you will be running two pairs of stereo speakers and two subwoofers. The good thing about these OMSUB200s is that they have a built in crossover to filter out the highs and you have the option to run satellite speakers off of them. Let me know if that about answers your question. Thanks. -Bm 2404
Mark • 12/17/2019, 2:17:43 PM Q Do the speaker inputs accept banana plugs?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Mark, Yes the AMP200 does accept banana plugs in the speaker inputs. CS 2417
Todd • 12/17/2019, 2:17:43 PM Q I would like to use this amplifier to power a single source, 9 zone whole house setup. The previous owner had a Jamo MPA-201 2 channel amp feeding into a Russound Pro-12 speaker selector. The JAMO has failed, thus am looking to replace with this amp. Configuration is as follows: Audio source: Yamaha RX-V1800 A/V Receiver (Zone 2 or Zone 3) Feed into Amplifier Feed into Russound Pro-12 speaker selector. Will this work?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Todd, Yes that is solid setup. CS 2452
Brad • 12/17/2019, 2:17:43 PM Q I am planning on using this amplifier to power a total of 16 x MK840 speakers in 4 different zones controlled by 4 impedance matching volume controls. Zone 1 has 7 speakers, Zone 2 has 4, Zone 3 has 3 and zone 4 has 2 speakers. I'm also going to be using a 4 zone speaker selector box. I'm curious is this amp will have enough power to fill the space as the speakers will be roof mounted at 9'6 from the floor. As well I'm unsure on how to best set the volume controls impedance (x_? setting) so the amp will be stable around 3 or 4 ohms when turned on. We're expecting to have all 16 speakers going about 90% of the time.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Brad, That's quite a system! The AMP200 is only intended to run 4-5 pairs of speakers (8-10 speakers), so it would be best to run our AMP300 instead. The AMP300 has plenty of power to run 8 pairs of MK840s. No matter how many actual zones you have, typically we recommend using each zone on a speaker selector for 1 pair of speakers. Think 1 Zone = 1 pair. However, you aren't limited to that. Ideally you would run two SSVC4 or DSM4 speaker selectors from the AMP300, one on each zone (Zone A & Zone B of AMP300). Then you would run each pair off each zone. Let us know if that answers your questions. Thanks. -BM 2463
