SKU: OSD-AMP300
OSD AMP3002-Channel 350W Per Channel, High Current Class A/B Stereo Amplifier Toroidal Transformers
A heavy-duty 350-Watt A/B two-channel dual source amplifier for use as a remote or single amplifier.
Dual Source Switching
The AMP300 also includes dual source switching to connect two audio sources and toggle between them for greater listening flexibility. Automatic source switching switches between connected sources with a priority signal-sensing feature, so if a DVD player is connected to input 2, then you decide to stream a movie through a game console, when the console is turned on, the AMP300 automatically switches to that source. The AMP300 also includes a variable delay control that lets you adjust the amount of time needed to "listen" for a signal from your main input, between 3 and 15 seconds. This prevents gaps between music tracks from accidentally switching your inputs. This high power amplifier includes two RCA signal level inputs so with the addition of an RCA-to-mini stereo cable (sold separately), you can connect your smartphone or other device.
Plenty of Power for the Price
Pair our AMP300 with the power-hungry speakers, and the sound quality will transform your listening experience. Rated at 350 Watts per channel peak power (470 Watts Bridged Mono into 8 ohms), the AMP300 can be configured as bridged or stereo. In bridged mode, you can combine the left and right channels into one audio channel which bumps up the power to a whopping 470 Watts (8 ohms). When playing dual sources, switch to stereo mode which reduces the power to 350 Watts per channel. It is the only high current 2 ohm load stable amp in the market.
Features
The AMP 300 also includes two sets of speaker outputs with front panel controls, auto-on signal sensing or 12-volt trigger, rear panel master level controls, dual line-level inputs with priority override switching and dual voltage of 110V/220V and auto signal sensing. This amp has a clean, brushed metal front panel with a volume control, power on and off button and a balance control knob to adjust the balance between the left and right channels and dial in just the right sound level mix. Special protection circuitry safeguards the amp from a short circuit.

Is there an output for a powered sub woofer?

Hi Larry,
Yes - The Line 2 has an output for a powered subwoofer but will only work with Line 2 Input.

Hello,
I have high end receiver with many speakers in my home. Everything has been satisfactory except the 15" driver old pro series Cervin Vega speakers that are 4 ohm. My HDMI receiver rated at 6/8 ohms at best just won't drive them like my old 4 ohm rated receiver did. Will your Osd-amp300 fit the needed void? Please keep in mind I'm only trying to power the 4ohm speakers the other speakers will have receiver power. Thank you for your reply.

Hi Darren,
Yes - our AMP300 can handle down to a 2ohm load, so 4ohm will be nothing for it.

Hi, I have a Yamaha RX-V673 with 2 zones. I'm currently running 5 ceiling speakers in zone 1 and have zone 2 hooked up to your ISS4 speaker switch with a set of rock speakers on one button to our courtyard and a set of rock speakers on another button to our back yard. It works great, but now we'd like to add a pair of ceiling speakers to 2 other rooms (adding 4 more speakers). I was thinking of running my zone 2 to this AMP300, then outputting the ISS4, Thus powering my 4 rock speakers and my 4 ceiling speakers, but I read in these comments if you use 2 different sets of speaker selectors you get more power? What would be a good configuration for what I'm trying to do? Thanks!

Hi Michael:
Are you using Volume Controls for your two outdoor speakers? It is wise to add an independent amp from the zone 2 output when using a speaker selector. Especially if you go to more than two pair of speakers which you are planning to do. The ISS4 speaker selector features a protection switch that will need to be enabled if you are not using Impedance matching Volume Controls and listening to more than two pair of speakers at a time. When you use the protection switch the signal is routed through the internal resistors and making sure that your amplifier sees a proper impedance load. The trade off is your power is cut in half. That is why we recommend using impedance matching volume controls like our OVC100 for outdoors and SVC300 indoor for your two in-ceiling speakers and disabling the protection switch on the ISS4. Adding the volume controls also gives you additional control at the zone where the speakers are located. Another path you can go is to purchase the AMP200 and the SVC4 Speaker selector featuring internal impedance matching volume controls.
You do have options

I am in the process of finishing up my sound system. I have a ICE530 speaker in each room with a separate volume control. I have a 16-2 wire going from each control to a distribution panel and then another wire going to where I will put my amplifier. I have a total of 13 speakers in this system. Will this Amp handle that? I have 2 more ceiling speakers for my surround sound for movies/TV. How do I hook it up to I can listen to music upstairs and someone can watch a movie downstairs with the surround sound or listen to music through the surround sound speakers?
Customer Service • 12/17/2019, 2:17:43 PM
Hi John,
That definitely will work with the AMP300. You'll connect your speaker selector or speaker distribution panel to the AMP300 Zone 1 and then run a volume control off each zone of your speaker selector.
For the surround sound, you'll want a home theater receiver that does 5.1 or 7.1 surround sound. You can run an RCA cable from most home theater receivers to an external amp, in this case being the AMP300. Thus you will run your home theater speakers off the surround sound receiver and your stereo speaker around the house off the AMP300.
