Whether you're building a component system, powering a pair of full-range speakers, or just pounding away with a subwoofer, there's an Infinity Reference series amp ready to take on the job. Boasting impressive power ratings and fine-tuned controls, these amplifiers are capable of sending your music to new sonic heights. It's all thanks to high-output MOSFET power supplies — which ensure maximum power delivery to your speakers for efficient operation — and variable filters that let you contour the output to fit your music. The Infinity Reference 7520a 2-channel amplifier is designed to work in a variety of applications. With 97 watts RMS in stereo mode, it can drive a pair of full-range or component speakers. Or, bridge the channels to mono and power a subwoofer with 283 watts of RMS power. The built-in bass boost juices your lows up to 12 dB at 50 Hz.
