AHB2 Instruction Manual Rev F Page 3
Introduction
Thank you for purchasing the Benchmark AHB2 audio power amplifier. To take full advantage of
the extraordinary performance of this amplifier, and to enjoy long and trouble-free use, please read
this manual carefully.
Product Overview
True HRA Performance
The AHB2 is a reference-grade audio power amplifier that is specifically designed to complement
the performance delivered by the finest High Resolution Audio (HRA) recording and playback
systems. The SNR and THD performance of the AHB2 put this amplifier in a class by itself.
Virtually Noise Free
The AHB2 delivers a SNR that exceeds 132 dB A-weighted. This makes the AHB2 15 to 30 dB
quieter than most top-quality power amplifiers. 132 dB is approximately equivalent to the noise
performance of a perfect 22-bit digital system.
Virtually Distortion Free
A THX-patented feed-forward error correction system virtually eliminates all traces of distortion at
all signal level and loading conditions. The AHB2 shows no traces of the crossover distortion that
can occur when push-pull outputs stages switch between output devices. Without crossover
distortion, low-level details are resolved with precision. At high output levels, the AHB2 remains
virtually distortion free while driving heavy loads.
Patent Information
The AHB2 incorporates patented THX® Achromatic™ Audio Amplifier Technology (THX
AAA™) which is licensed from THX Limited.
