The output of the correction amplifier is a high-precision mirror of the errors produced by the main class-AB amplifier. Error-Correction Amplifier - The error-correction amplifier is a small ultra-clean amplifier that feeds a correction signal forward to the main output. The main amplifier errors are measured, inverted, and buffered by the error-correction amplifier.Overall, the distortion produced by the AHB2 is so low, that it approaches or exceeds the measurement limits of some of the finest audio test systems.

The AHB2 is virtually distortion free at low levels, at maximum output, and everywhere in between. Low-level musical details are delivered without the masking effects of crossover distortion. Difficult loads are driven with near-perfect clarity. Distortion does not change with loading, and does not rise near maximum output. The THX- patented feed-forward error-correction system in the AHB2 is much more effective than traditional feedback error-correction systems. These amplifiers are combined to create a near perfect null of all distortion components.

The main class-AB amplifier provides the bulk of the power while the auxiliary amplifier provides a low-power error-correction signal. Feed-Forward Error Correction - Each channel of the AHB2 is equipped with a main amplifier and an ultra-clean low-power auxiliary error-correction amplifier.Benchmark and THX collaborated to combine unique THX-technologies with Benchmark's uncompromising attention to performance and quality. The AHB2 combines class-H, and class-AB amplifier technologies with feed-forward error correction. AHB™ Amplifier – This unique amplifier uses THX-patented AAA™ (Achromatic Audio Amplifier) technology to achieve high efficiency and vanishingly low distortion.

In many ways, the AHB2 is a complete 180 degree departure from traditional high-end amplifier designs. The performance of the AHB2 would not have been achievable without taking a radical approach to power amplification.
