REF475A
4-Channel Full-Range Amplifier
Mfg Model:
REF475A
4-Channel full-range amplifier with on-board electronic crossover and variable bass boost.
SPECIFICATIONS
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.
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
A variable bass boost circuit is provided to optimize the low frequency 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 Reference 475a's high-output PWM MOSFET power supply ensures optimum power delivery into numerous impedances with low distortion.
