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 Filter
For extra flexibility, variable LPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D8701 LPF is adjustable from 40 Hz to 240 Hz.
Turn Up the Bass
Every new Pioneer Class-D amplifier has a wired bass boost remote control for optimal bass level adjustment according to listening preferences and music characteristics.
