5-CHANNEL CLASS-D AMPLIFIER
With the focus on sound precision as well as high power levels, Pioneer is proud to introduce the GM-D505.
Setting a new standard of excellence, this 5-way Class-D amplifier delivers powerful and clear output through
five channels: 4 analogue and 1 Class-D mono. This ingenious set-up — complete with Low Pass and High
Pass Filters — lets you directly connect four speakers and a subwoofer for a maximum power output of
4 x 100 W plus 1 x 300 W. Highly efficient Class-D technology requires less electrical current. This means less
heat generation or, in other words, a superb compact design packed with clean and distortion-free sound
quality.
