Bass Boost featured in the GM-A6604 can be set to levels variably between 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-A5602 allows adjustment in three steps: 0 dB, 6 dB or 12 dB.
Allows you to connect the amplifier to your source without RCA-type inputs and without the need for adapters.

When connected to an OEM receiver or a receiver without RCA input using speaker wire, the amplifier is turned on at the same time as the receiver.
Pioneer‘s amplifiers automatically detect an input signal and select an input signal mode between the RCA level and the speaker level.
