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-)
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.
Variable HPF & LPF
For extra flexibility, variable LPF and HPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences.
- GM-D9704 / GM-D8704 - Variable LPF/HPF: 40-500 Hz
- GM-D9701 / GM-D8701 - Variable LPF : 40-240 Hz
- GM-D9705 - Variable LPF/HPF (A-Ch. and B-Ch.): 40-500 Hz
- Variable LPF (SW-Ch.): 40-500 Hz
Turn Up The Bass
Every new Class-D amplifier has a Bass Boost Remote Controller for optimal bass level adjustment according to listening preferences and music
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
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.
