    • Equipped with 350 Watts per channel peak power, 470 watts Bridged Mono into 8 ohms
    • Dual source capable for greater listening flexibility

    • Protection circuitry safeguards the amp from a short circuit
    • Can be configured as bridged or stereo amp
    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.

    Steve • 12/17/2019, 2:17:43 PM I want to hook amp to zone 2 on my Yamaha receiver, Will my receiver still control the bass and treble and where should I put Equalizer before or after receiver.
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Steve The Equalizer would be connected between the Receiver and AMP300 CL 2005
    pdo • 12/17/2019, 2:17:43 PM Every now and then, the AMP300 stops and I have to cycle power on it to get it to come back. I'm only running 3 sets of small outdoor speakers with it, so should not even be coming close to overloading the amplifier. Any ideas what may be causing this?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hello, We'll need more information from you. For instance, what impedance are your speakers and what kind of wiring are you using? Are the speakers run in parallel off one speaker output? What are your gain settings? CL/MA 2007

    I am using the ASP660 from OSD and the 16 Gauge 2-conductor Higher Strand Count Oxygen Free Speaker Cable to connect. I'm using the SSVC4 4 Zone speaker selector box to connect them all in parallel to the same output from the AMP300. The speakers are set to the 8Ohm setting.
    Steven • 12/17/2019, 2:17:43 PM I have a Yamaha 75 watt per channel stereo receiver and 4 speakers that can handle a lot more power than 75 watts, so all I want this amp for is more power through zone 2, will this amp let me use speakers A and B at the same time, does the bass and treble from receiver still adjust sound output or do I need an equalizer for that.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Steven, You would need an equalizer for that. You can play A + B at the same time no problem. This AMP is sold in out 8 zone kit, so at most it can drive is 16 speakers (8 pairs) at the same time. Its our best amp. CL 2040
    Angel • 12/17/2019, 2:17:43 PM Can I connect an airport express to this amp and to the ssvc6 that I recently purchased from u guys. I need to power 3 pairs of outdoors spekears
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Angel: I believe you will need a DAC (Digital to Analog Converter) to connect the Airport express to the Analog input of the AMP 300. Check out the following link for a DAC that would work: http://www.amazon.com/D3-Digital-Converter-Optical-Toslink/dp/B005K2TXMO/ref=sr_1_2?ie=UTF8&qid=1377107465&sr=8-2&keywords=external+dac The Airport Express uses an Mini jack/Optical output which would connect to the DAC, then just connect a RCA stereo analog pair of cables to the AMP 300.
