Pioneer GM-DX874 LIMITED EDITION 4-Channel Amplifier

PioneerSKU: GM-DX874



Class-D 4-Channel Bridgeable Amplifier with Gold RCA Terminals, Hi-Res Audio Capable, HQ Sound Parts and Wired Bass Boost Remote.


Big Power, Small Size

Pioneer’s 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 ohm 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. These amplifier's LPF and HPF are adjustable from 40 Hz to 500 Hz.



Pioneer Branded Electric Elements

High quality elements provide high sound quality and stable power supply.



Gold Plated Terminals

Gold plated terminals provide the ability to maintain an accurate signal with increased electrical conductivity, prevent corrosion and provide enhanced durability with excellent resistance against wear.



Hi-Res Audio

High Resolution ability provides a super high frequency playback over 40kHz, and a wide dynamic range. Even if the source is not Hi-Res, wide dynamic range provides a more detailed audio playback.


Aluminum Top Board

A high quality cosmetic only available on LIMITED models.
