Amplify your audio experience with new Class-D Amplifier
Pioneer’s 4-channel, GM-DX874 is compatible with high-resolution audio that offers sound reproduction with extraordinarily realistic atmosphere. With superior-quality audio parts and fine acoustic tuning yield outstanding sound quality. A high-capacity audio power source capacitor ensures stable power supply even at high power output.

Features:

High-resolution Audio
With sound data that exceeds the volume of CD sound information, GM-DX874 reproduces outstanding audio quality from high-resolution audio sources, offering incredibly realistic atmosphere. Hi-Res Audio employs music information more accurately then CD: - CD specs (44.1 kHz / 16-bit) - Hi-Res Audio specs (96 kHz- / 24-bit-)

Variable HPF & LPF
Adjust LPF & HPF (40-500 Hz).

Turn Up The Bass
The GM-DX874 also features a Bass Boost Remote for optimal bass level adjustment according to listening preferences and music characteristics.

Automatic Signal Sensing and Turn-On
Pioneer's Class-D amplifier automatically selects an input signal mode between the RCA level and the speaker level detecting an input signal. In the case of speaker line input, the amplifier will automatically switch on when the receiver is turned on.

Protection Control System
Designed to bolster reliability, this system reduces the risk of damage due to an overly high input power, by sensing the internal temperature and moderating the signal on-the-fly.

High Quality Sound Parts and Tuning
Audio film capacitors and low-impedance coil are used for the output LC filter to ensure excellent sound quality. Audio tuning based on the reproduction of the original audio source allows everyone to experience the difference in sound quality when connected.

High-capacity Audio Power Source Capacitor
Pioneer's original high-capacity audio power source capacitor contributes to higher sound quality and stable power allotment even at high output.
