Key Features

4 channel D Class 1200W Amplifier - Pioneer GMDX874

Hi Res Audio
Gold RCA terminals and a high capacity audio source capacitor ensures stable power supply, even at high power output.

To prevent circuit shutdown, Pioneer's GM-DX874 digital amplifier circuit includes a "Protection Control System" senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 Ω connection. This design enhances the flexibility to connect multiple subwoofers to a system.

For extra flexibility, easy installation is guaranteed thank to "Automatic Signal Sensing and Turn-On", which automatically detects an input signal and turns the amplifier on and off when connected via the speaker line input.

Variable LPF and HPF means you can adjust the audio frequency more according to the speaker, subwoofer characteristics and personal listening preferences. The GM-DX874 LPF and HPF is adjustable from 40 Hz to 500 Hz. The GM-DX874 also includes a wired Bass Boost Remote Control.

The GM-DX874 has a sleek design thanks to an aluminium hairline panel on the top plate enhancing the high quality sense of design and a total of 1200W.
