Overview 

Big Power, Small Size

Pioneer’s extra-efficient Class-FD 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 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, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D8704 LPF is adjustable from 40 Hz to 500 Hz.
