Pioneer GM-DX874 Class-D 4-Channel Car Amplifier
Pioneer GM-DX874 four-channel amplifier will deliver 100 watts RMS to each of your front and rear speakers, for powerful music that’ll make every ride a pleasure. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out-of-the-way spaces. The frequency response of this amplifier stretches up to 50,000 Hz, so it’ll support crystal-clear, Hi-Res playback. Pioneer uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance.
Pioneer GM-DX874 new extra-efficient Class-D digital amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.
Improved Circuit Design
To prevent circuit shutdown, Pioneer’s new digital amplifier circuit “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.
Variable Low-Pass and High-Pass Filter
For extra flexibility, variable LPF and HPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-DX874 LPF and HPF are adjustable from 40 Hz to 500 Hz.
