12/11/2023 0 Comments Using benchmark ahb2 in bridged mode![]() One independent test lab had this to say about the AHB2: Last but not least, the FPGA-based protection system in the AHB2 provides the robust protection necessary in a laboratory environment. The extended bandwidth provides the precise phase response that their application requires. The -3 dB bandwidth extends from 0.1 Hz to 200 kHz with an exceptionally flat response. Distortion is virtually non-existent, even when heavily loaded with low impedances. The AHB2 offers a solution that is more than 15 dB quieter than other top-quality high-end amplifiers. They needed an amplifier with exceptionally wide bandwidth, low noise, low output impedance, low distortion, and bulletproof overload protection. In late 2016, SEAS contacted Benchmark about the possibility of using the AHB2 power amplifier in a laboratory environment. "A Benchmark AHB2 amplifier is used, which has excellent signal-to-noise ratio and bandwidth, low output impedance, and is suitable for laboratory use (with advanced overload protection)." "Is the AHB2 suitable for laboratory use?" This new measurement system was documented in the December 2017 Journal of the Audio Engineering Society (link in references).Īccording to the AES paper, the SEAS team selected the Benchmark AHB2 for the following reasons: They created an innovative test system that measures loudspeaker motor strength and moving mass with higher accuracy than previous methods. SEAS, a well-known manufacturer of high-quality loudspeakers, selected the Benchmark AHB2 as a key component for use in testing loudspeakers. SEAS driver test system uses Benchmark AHB2
