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 ff 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. The GM-D8604 LPF and HPF are adjustable from 40 Hz to 500 Hz.
Speaker Level Inputs:
The GM-D8604's speaker level inputs allow you to connect your OEM unit (or any unit that doesn't have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you've got a Pioneer amp in your vehicle.
Pioneer® was founded in 1938 in Tokyo, Japan by Nozomu Matsumoto – a man with a passion for music that he hoped to share with the world through high quality audio speakers. That passion began with a small operation to repair and manufacture speakers in Matsumoto's garage. It has since grown to international stature as a manufacturer of audio and video products for use at home, in the car, and in business environments. The element that has not changed in nearly 70 years is the passion for audio and video products that Pioneer hopes to share with the world. From the employees at their research labs looking for the "next big thing" to the engineers at Pioneer's factories focused on quality assurance to brand's product trainers explaining the new technology to customers – Pioneer remains passionate about creating an unbeatable entertainment experience.
