About the Infinity Reference 7520a

Tim Sprinkle
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.

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. And, since every Infinity Reference amplifier is CEA-2006 compliant, you'll know you'll get the power as advertised.

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.

Features

Status LEDs: The amplifier has the following status LEDs:

  • Clip: indicates the amplifier is being overdriven, and your speakers may be in danger. This should blink only on musical peaks, and not be on constantly.
  • Power: indicates the amplifier is on
  • Protect: indicates any of the following problems: DC voltage on amplifier output, overheating, under voltage, over voltage, and short circuit in the speakers or wire

Variable Filter: The internal filter can be set for low-pass, high-pass, or full-range operation. In the low-pass and high-pass modes, the filter can be adjusted from 32 to 320 Hz. In each case, the filter has a slope of 12 dB per octave.

Bass Boost: For added low frequency performance, this amplifier has a 0 to 12 dB variable bass boost centered at 50 Hz.

Preamp Outputs: The preamp output jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. These outputs provide a full-range signal.
