Description

The Pioneer GM-D8704 is a bridgeable amplifier delivering 1200W over 4 channels, engineered with Class-D technology, ideal for your car audio setup without taking up excessive space.

Compact and Powerful:
Pioneer's latest Class-D digital amplifiers offer substantial power output while being 50% smaller than the previous GM-Series Class-AB amplifiers. This compact size enhances installation flexibility without compromising performance.

Enhanced Circuit Design:
Featuring Pioneer's Protection Control System, this digital amplifier actively monitors internal temperature to prevent circuit shutdown. This intelligent system automatically adjusts input levels to maintain stable, durable circuitry, reducing the risk associated with high input power, even in demanding 1 Ω connections, enabling multiple subwoofers to be connected to the system.

Adjustable Filters:
The GM-D8704 amplifier comes with variable Low Pass Filter (LPF) and High Pass Filter (HPF) options, allowing for fine-tuning of audio frequencies to match subwoofer characteristics and personal preferences. The LPF and HPF are adjustable within a range of 40 Hz to 500 Hz, providing flexibility in sound shaping.

Compatibility and Convenience:
In the absence of a Pioneer head unit, the GM-D8704 offers speaker level inputs, enabling seamless connection to your OEM unit or any unit lacking RCA-type inputs. This feature eliminates the need for additional adapters, expediting installation, saving costs, and ensuring a Pioneer amp integrates smoothly into your vehicle's audio system.

Key Features

  • Big Power, Small Size: Pioneer's Class-D amplifiers deliver significantly improved power output while being 50% smaller compared to the current GM-Series Class-AB amplifiers. This compact size enhances versatility for installation and performance.
  • Variable Low-Pass Filter (LPF): Offers flexibility with an adjustable LPF, allowing fine-tuning of audio frequencies to match subwoofer characteristics and personal listening preferences. The GM-D8704 LPF can be adjusted from 40 Hz to 500 Hz.
  • Protection Control System (PCS): Pioneer’s PCS actively monitors input voltage, current consumption, and operating temperature. It automatically adjusts the amplifier’s output to ensure stable operation during extended listening periods or in high-temperature conditions.
