Technology of GM Series:
From dramatic distinction to dramatic design, Pioneer's new GM-Series amplifiers are thrillers in every sense, pushing the limits of flexibility and functionality.
Variable HPF (High Pass Filter) allows for adjustable frequency between 40 Hz to 500 Hz and greater car audio system flexibility according to subwoofer characteristics and personal listening preference.
Bass Boost featured in the GM-A6704 and GM-A5702 can be set to levels variably from 0 to 12 dB for optimal bass. This precise control can enhance the overall balance and impact of all sounds according to listening preference and music style. The GM-A5702 allows adjustment in three steps: 0 dB, 6 dB or 12 dB.
Growing Power, Shrinking Size:
New Pioneer amps brilliantly integrate high-power performance superior to that of previous models in space-efficient size for flexibility of installation in various car cabins.
Automatic Signal Sensing and Turn-On:
Pioneer amplifiers automatically select the proper input signal mode, either RCA or speaker level. When the receiver is turned on, the amplifier automatically turns on. When connected to an OEM receiver or a receiver without RCA output and utilizing speaker level output, the amp automatically senses the input mode and powers up in sync with the receiver.
When connected to an OEM receiver or a receiver without RCA output using speaker wire, the amplifier is turned on at the same time as the receiver. Pioneer's amplifiers automatically detect the input signal and select RCA level or speaker level.
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 80 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.
