Benchmark AHB2 Amplifier Rack BlackBM-AHB2RM/B
The Benchmark AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion.
The dynamic range of the AHB2 approaches 130dB, making it 10 to 30 dB quieter than the typical reference-quality power amplifier. You will discover previously overlooked nuances, dynamics, and detail in your favourite recordings and experience the full potential of the latest high-resolution 24-bit PCM and 1-bit DSD audio formats. The AHB2 delivers true High-Resolution Audio.
The frequency response of the AHB2 extends beyond 200 kHz, to deliver the ultrasonic detail and fast transients captured by high-resolution recordings. At the other end of the audio spectrum, the low-frequency response extends below 0.1 Hz. The extended frequency response delivers a nearly perfect impulse response, and a nearly perfect phase response.
Distortion performance exceeds that of class A amplifiers, while the efficiency exceeds that of traditional class AB amplifiers. Low-level details and reverb tails are rendered with a stunning resolution.
The low-noise input amplifiers on the AHB2 are equipped with precision balanced inputs. Benchmark considers balanced inputs essential in a true high-resolution system.
Equipped with high-quality binding posts, and SpeakON output connectors. The SpeakON connectors are designed for heavy-duty commercial sound systems and provide much better electrical connections than binding posts. Benchmark highly recommends the use of the twist-lock SpeakON output connectors.
