INFINITY REFERENCE 7521A
260 Watt 2-channel power amplifier


 The Reference 7521a's high-output PWM MOSFET power supply ensures optimum power delivery into numerous impedances with low distortion. 

 The 7521a 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 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. 

 High-level and low-level input are provided allowing you to interface the Reference 7521a with either an aftermarket or factory installed head units.
