The Benchmark AHB2 High-Resolution Power Amplifier is a high-performance audio amplifier designed for professional use. It features a range of technical specifications including output power, input sensitivity, and input impedance. The amplifier is capable of delivering 100 W/channel into 8 Ω, 130 W/channel into 6 Ω, 190 W/channel into 4 Ω, 240 W/channel into 3 Ω, and 200 W Bridged Mono into 16 Ω. It also has a signal-to-noise ratio of 132 dB A-weighted in stereo mode and 135 dB A-weighted in bridged mono. The amplifier includes features such as input sensitivity levels, cross talk performance, frequency response, and THD+N specifications. It is designed for use with a variety of audio sources and is suitable for professional audio applications.
