A solid high-power amplifier does more than make the sound you love louder. A well-built power amp cleans up sound quality, improves bass response and delivers the right amount of power to efficiently drive multiple speakers in distributed audio system or home theater. Our AMP300 is a flagship amp that sells well for a reason. This 350-Watt A/B two-channel dual source amplifier is ideal for use as a remote amplifier to power your whole house audio system or as a single amp for a dedicated home theater or media room, and you won't find an amp with the same features that we pack in at such an affordable price. It is stable at 2 ohm load.

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.

Tony • 12/17/2019, 2:17:43 PM Q I have 2 mi6 amps connected to a Yamaha rx-v867 each driving a klipsch tower and the volt meters don't move. Is this because of how it's connected? Can you recommend how it should be hooked up?
Customer Service • 12/17/2019, 2:17:43 PM
A How do you connect? Can you draw a diagram for your hook up? dave
marty shuman • 12/17/2019, 2:17:43 PM Q will this amp play a and b speakers at the same time
Customer Service • 12/17/2019, 2:17:43 PM
A Marty, Yes the AMP300 will play both A and B speakers at the same time. CL
michael • 12/17/2019, 2:17:43 PM Q i have a jvc rx 6030 hme theater system. Can I hook the OSO amp to this system?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Michael: It appears the JVC RX 6030 does not have a pre-amp output with a dedicated zone 2. The Speaker level outputs are all dedicated to the 5.1 processing. The AMP300 would not work with this Receiver. TL
jim W • 12/17/2019, 2:17:43 PM Q i already have a Intergrated Amp I need a another Amp to help Power (8) 8 ohm speakers will this unit work for me. was looking to power 4 of the 8 speakers with it. thanks

A Jim, Our Amp300 will handle this application, no problem. CL
Michael Woods • 12/17/2019, 2:17:43 PM Q I have bought a small resort. We want to run one sound source in the restaurant and one sound source in the bar and patio; all controls to be set up and contolled from behind the bar. I have purchased a 2 channel 5 zone speaker controller. We will want to run either satelite or internet sources plus an ipad dock. Total sets of speakers on each channel will be 8. Will two of these amps be enough power for each channel? Thanks for your help. M. Woods mwoods@pklodge.com
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Michael: Based upon your application I would recommend an AMP300 per each location. One for the Resurant and one for the Patio/Bar. I am a little confused on application for the single 2 channel 5 zone speaker controller. I would have recommended going with our SSVC4 Speaker selector per amplifier. That way you can connect four pairs of speakers for both the Resturant and the Bar/Patio locations. The SSVC4 features Internal Volume Controls for each pair of speakers while controlling the impedance back to the amplifier. This would give you additonal control from the central location. You could then have a dedicated source connection to a computer (for Itunes or streaming media) using a Y adaptor to split between the input 2 of each amplifier. You could then have the option of plugging the iPad into either amplifier Input #1 and when you play it would take priority over the other source. These Amplifiers are very flexible and appear to be a great fit. We can also help you out with any of your Speakers and CL3 rated speaker wire needs as well. Thank you for considering OSD Audio. TL
