    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.

    Michael • 12/17/2019, 2:17:43 PM I have a pair of old Sherwood towers I want to set up on my deck and need the "right" receiver. Each tower has a 10" sub, a 6" mid and liquid metal tweeters. I'm not sure what each tower's power rating is, but they could make the windows rattle when they ran from their original amp (now defunct). Can anyone offer their recommendation?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Michael, Thanks for asking! As long as the speakers run between 2-8 ohms, and can handle up to 150 watts each, I don't see why the AMP300 wouldn't do the job efficiently. It is a high-current amplifier that can run upwards of 8-10 pairs of our speakers at a time. Call us for more details. 562-697-2600. Thanks! -BM 2243
    Nikola • 12/17/2019, 2:17:43 PM Hi there, I want to bi-amp my pair of klipsh f-30 on this amp. Is that possible? Thanks. Nikola
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Nikola, Very good question. One in fact that I can fully answer. The amp is not set up to bi-amp, but you may be able to connect Speaker A to one input and Speaker B to another input. I don't know if this will have a benefit though. I hope that helps. Thanks! -BM 2253
    mike • 12/17/2019, 2:17:43 PM Hi there need some help im trying to build a nice sound on my living room im going to connect a 5.1 surround what do I need to push the speaker and sub woofer also connecting 2 outside speakers
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Mike, Do you have a 5.1 surround sound receiver? If so, great. You can run our AMP120 off it to power your two outdoor speakers. Just make sure that your home theater receiver has an output that will accommodate an external amp. If you do not yet have a home theater receiver, take a look at the Yamaha receivers that we sell under our home theater section. We have two options for 5.1 and two for 7.2. The only one that actually accommodates a 2nd zone is the YH-RX-V675. Let us know if you have any further questions. Thanks! -BM 2320
    Mike • 12/17/2019, 2:17:43 PM Im going to connect center MK IW 550LCR 2 PAIRS OF MKW850 and 1 10"IWS10 PRO SERIES And 2 outside speakers what do I need to make this right Im starting from scratch
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Mike, Sounds like you're setting up a 5.1 surround sound system and want an extra pair outside. In order to do this you'll need a 5.1 surround sound receiver. Navigate over to our Home Theater section and check out the Yamaha receivers. The only one that has a zone 2 would be the YH-RX-V675. The AMP300 would be useful if you were wanting to power multiple sets of speakers around the house to play stereo, but not surround sound. Let us know if that answers your question. Thanks! -BM 2321
    Peter • 12/17/2019, 2:17:43 PM I have a home that has B&W speakers in every room of my home with controls and IR remotes and have no idea what I need to connect all of these wires coming out of my wall Please help
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Peter, Thanks for the question! To start, you're going to need a multi-zone speaker selector. Depending on how many rooms you have, you can go with the ISS4, ISS6, ISS8 or even the TSM12. Each pair of speakers will be run back to their individual zones on the speaker selector. The AMP300 will then be wired to the input of that selector, providing the power to each zone. As for the IR, the AMP300 is an analog amp, so it is not directly compatible with IR. How does the IR system work with these speakers? -Bm 2336
