Pioneer class-D amps package high power into compact design

LAS VEGAS, USA: Pioneer Electronics (USA) Inc. has introduced three new high-efficiency “GM Digital” series Class-D amplifiers, the 4-channel GM-D9500F and the monoblock GM-D8500M and GM-D7500M.

Inherent to Class-D amplifier design are vastly improved electrical and thermal efficiencies, allowing the amplifiers to produce the same power output as conventional amplifiers more than double their physical size. The new Pioneer GM Digital series Class-D amplifiers feature dynamic, balanced sound quality combined with high power output, all in an extremely compact chassis.

“While it is commonly understood that the addition of an external amplifier to an in-vehicle entertainment system can make the system play louder, the improvement in sound quality is often overlooked. An amplifier contributes to extended frequency response, greater dynamics and a less constricted sound overall,” said Ted Cardenas, director of marketing for the mobile business group of Pioneer Electronics (USA) Inc.

“The new GM Digital series Class-D amps are also very efficient and compact, allowing them to be installed practically anywhere in the vehicle.”
