Pioneer GM-A4704 Amp in Kenya
Versatile Performance
The Pioneer GM-A4704 is a punchy Class-AB 4-channel amplifier designed to bring clarity and depth to your vehicle’s soundstage. It delivers a 520W maximum power output while providing a clean 40W RMS x 4 at 4-ohms. This bridgeable unit offers total installation freedom, allowing you to power four speakers or bridge the rear channels to drive a single subwoofer with 130W RMS. Consequently, this amplifier serves as a versatile hub for users looking to upgrade their factory audio without the need for multiple heavy components.
Precision Frequency Tuning
This system features an integrated variable high-pass filter (HPF) that allows you to adjust your audio frequencies between 40Hz and 500Hz. This targeted adjustment ensures your speakers receive only the signals they can handle, minimizing the risk of distortion and protecting your hardware. The amplifier also includes a fixed 80Hz low-pass filter (LPF) and a selectable bass boost of 0dB, 6dB, or 12dB at 50Hz. Furthermore, the gain adjustment control of up to 6.5V lets you align the GM-A4704 amplifier’s output perfectly with both factory and aftermarket head units. These tools provide the precision needed to customize your sound staging for a more immersive listening environment.
Advanced Protection
The Pioneer GM-A4704 is built with a one-body heat sink for efficient thermal management and a 30A fuse rating to safeguard against electrical surges. It features automatic signal sensing and turn-on, which detects the input mode (RCA or speaker level) to power up the amp in sync with your receiver. The compact chassis measures 326mm x 60mm x 215mm, making it easy to tuck under seats or behind cabin panels. Its ultra-low total harmonic distortion of less than 0.05% ensures that your music remains pure and energetic even at high volumes. Ultimately, this Pioneer-engineered component combines durability with the refined audio characteristics of the GM series.
