• The Reference 475a's high-output PWM MOSFET power supply ensures optimum power delivery into numerous impedances with low distortion.

• A variable bass boost circuit is provided to optimize the low fequency performance of your system.

• Full range preamp outputs are provided facilitating multiple amplifier hookups without the need for costly Y-adapters or signal splitters.

• The 475a comes outfitted with a variable 12dB per octave electronic crossover allowing you to optimize system tuning based on speaker location and accompanying loudspeaker components

• The RCA low-level inputs on the 475a have allow for connection to both a preamp level signal and direct connection to a high-level factory head unit.
