The new Reference series amplifiers build upon Infinityís reputation for performance and design thatís been leading the industry for almost 40 years. The Reference series features a high-performance PWM MOSFET power supply for optimal power and minimal distortion. Class AB amplifiers offer audiophile-quality performance and the best compromise between efficiency, low distortion, and maximum available headroom and output power.

Flexibility is the name of the game, with high and low-level inputs for easy integration with any system, preamp outputs to feed additional amplifiers, and variable 32-320 Hz high-pass and low-pass crossovers to tailor the output to your specific speakers. A built-in variable 50 Hz boost adds just the right amount of low frequency contour for a superb bass foundation. A new low-profile heatsink design add installation flexibility as well. The outer shroud can also be removed and painted for a true custom-look to bring together your custom theme. The Reference series is the perfect balance of power, flexibility, and value that only Infinity can deliver.
