Features of GM-D8701

Bass Boost Remote

Every new class D Amplifier has a Bass Boost Remote Controller for optimal bass level adjustment according to listening preferences and music characteristics.

---

Highly Reliable Circuit Design

To prevent circuit shutdown, Pioneer-TMs 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-ohm connection. This design enhances the flexibility to connect multiple subwoofers to a system.

Other features of GM-D8701

Variable LPF

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.

Automatic Signal Sensing & Turn ON

Pioneer Class D Amplifier automatically select an input signal mode between the RCA Level and the speaker level selecting an input signal.
