About: Pioneer GM-DX874 Limited Edition 4-Channel Car Amplifier
The Pioneer GM-DX874 four-channel amplifier will deliver 100 watts RMS to each of your front and rear speakers, for powerful music. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out-of-the-way spaces. The frequency response of this amplifier stretches up to 50,000 Hz, so it will support crystal-clear, Hi-Res playback. Pioneer uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance. Speaker-level inputs allow you to install this amp in a factory system with no RCA connections. The amplifier switches its input mode automatically when it detects the high-level signal, eliminating the need to run a turn-on lead to your receiver or fuse box. Built-in high- and low-pass filters let you adjust the sound for your vehicle's interior, whether you're driving speakers or subs.
Pioneer’s extra-efficient Class-FD 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.
To prevent circuit shutdown, Pioneer's 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.
For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-DX874 LPF is adjustable from 40 Hz to 500 Hz.
Pioneer’s PCS continuously monitors the input voltage, current consumption, and operating temperature to automatically adjust the amplifier’s output to ensure operational stability during long listening sessions or when installed in high-temperature environments.
High quality elements provide high sound quality and stable power supply.
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.
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.
