BENCHMARK AHB2 POWER AMPLIFIER FOR SALE FULL

Most power amplifiers are well matched to the limitations of the CD format, but they fall well short of the capabilities of high-resolution formats. Power amplifiers are a weak link in most audio systems. The musical details and emotion captured on today's finest High-Resolution-Audio recordings can only be fully appreciated when every component in the signal chain is capable of true high-resolution performance.

With the AHB2, you will discover previously overlooked nuances, dynamics, and detail in your favorite recordings and experience the full potential of the latest high-resolution 24-bit PCM and 1-bit DSD audio formats. The frequency response of the AHB2 extends beyond 200 kHz. The dynamic range of the AHB2 is 132 dB, making it 10 to 30 dB quieter than some of the very best reference-quality power amplifiers. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. The AHB2 is the ideal match for the performance limits of High-Resolution-Audio (HRA) formats. Benchmark has raised the bar by introducing a new and revolutionary amplifier! The Benchmark AHB2 Power Amplifier is the quietest and cleanest sounding power amp ever! From the first watt to the last watt, no audio power amplifier offers lower noise or lower distortion than the AHB2. Schroeder Amplification is proud to be an authorized Benchmark dealer and user! We will also discuss some of the unique design features of the MB2S monitors that contribute to their impressive performance.This Benchmark AHB2 Power Amplifier is brand new and includes its full manufacturer’s warranty. We will also calculate the acoustic noise at a distance of 1 meter from each monitor. In this application note we will calculate the peak SPL produced by this system. They fully compliment the distortion-free performance of the AHB2 to provide a system with outstanding clarity while delivering high sound pressure levels. We were extremely impressed by the unusually clean, distortion-free, output of these monitors. This application note can serve as an example for calculating the maximum sound pressure levels and noise output levels for any amplifier/speaker combination.Īt the 143rd AES conference in NYC, we demonstrated two Benchmark AHB2 monoblock power amplifiers driving a pair of 4-Ohm PMC MB2S studio monitors.

In this application note we calculate the maximum output level and noise level produced by an amplifier/loudspeaker combination. It is nice to know that the AHB2 is also being used to test new and improved loudspeakers! Our goal was to create the ultimate amplifier for the enjoyment of music. The result is an amplifier with unrivaled transparency. The AHB2 was designed to outperform all competing power amplifiers in terms of noise and distortion. '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).' Īccording to the AES paper, the SEAS team selected the Benchmark AHB2 for the following reasons: This new measurement system was documented in the December 2017 Journal of the Audio Engineering Society. 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.

THD measures better than the -125 dB (0.00006%) limits of our test equipment. The end result is a fully buffered volume control with a signal-to-noise ratio that exceeds 135 dB. This application note discusses the engineering decisions that went into the development of this new analog volume control circuit. Given the extraordinary performance of these THX-AAA amplifiers, this would not be an easy task!

Our volume control would need to have lower distortion and lower noise than either of these amplifiers. We wanted to be able to place this volume control in front of our AHB2 power amplifier or in front of our THX-888 headphone amplifier board without diminishing the performance of either device. Our goal was to produce an analog-to-analog volume control with the highest achievable transparency. The volume control has a +15 dB to -122 dB range in 0.5 dB steps and is a key component in the HPA4 Headphone / Line Amplifier. Benchmark has introduced a new analog-to-analog volume control circuit that features a 256-step relay-controlled attenuator and a 16-step relay-controlled boost amplifier.
