Electronics (USA) Inc launched two
mono Class-D amplifiers to join its family of GM-series car stereo amplifiers. These new amplifiers are
designed to combine high power output and high efficiency while simultaneously producing the high-fidelity
audio Pioneer is known for. The GM-D7400M and GM-D8400M digital mono amplifiers, intended for
powering large subwoofers, use digital technology that make them 80-95 percent more efficient than
conventional class A/B amplifiers. Due to the increased efficiency, the physical size of the new amplifiers
was also reduced by 45 percent, making them more compact and easier to install.
The GM-D7400M and GM-D8400M also feature block-style terminals that allow power and speaker cables
to be securely connected to the amplifier without the use of crimped-on spade terminals. In the 2- and 4-
channel versions, the amplifiers accept speaker-level inputs for easy integration to factory OEM audio
systems.
* GM-D7400M: mono digital amplifier, 400 Watts and featuring an adjustable bass boost centered at
50Hz, a variable low pass filter between 40 and 240 Hz; and 2-Ohm stability.
Sounds Great, Looks Good
For many car audio enthusiasts, looks are as important as sound quality, and Pioneer’s GM series of
amplifiers offer a smooth, refined look. Each has a black heat sink complemented by a brushed aluminum
center and blue LED power indicator. Large cast aluminum heat sinks are used for increased heat dissipation
for cooler operation with tremendous reliability. Oversized power terminals and speaker level inputs offer
more flexibility in installation while the built-in crossovers provide better audio control.
