Benchmark DAC2 D Digital to Analog Audio Converter

Select Colour

This Benchmark DAC in keeping with the DAC 2 range has the same performance of the DAC2 HGC but without the analog inputs and the 12V trigger. Keeping the specs inline with DAC2 D, it has lower noise, lower distortion, improved accuracy, outstanding musical detail, precise stereo imaging, an advanced digital filter design, and a new high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmark's new UltraLock2™ jitter attenuation system. Internal digital processing and conversion is 32-bits, and includes 3.5 dB of headroom above 0 dBFS. Four balanced 32-bit D/A converter are summed together for each balanced output. The performance of the DAC2 D exceeds the measurement limits of today's state-of-the art test equipment. Discover the analog sound of the DAC2 D.

    • Benchmark DAC2 D PRODUCT FEATURES:

      The DAC2 D combines active analog gain control, passive low-impedance attenuators, a 32-bit digital gain control, and a servo-driven volume control. All inputs are controlled by the rotary volume control. This volume control moves in response to commands from the remote control. Digital inputs never pass through an analog potentiometer. Digital inputs are precisely controlled in the 32-bit DSP system. The DSP system preserves precise L/R balance, and precise stereo imaging, while avoiding any source of noise and distortion. Benchmark's unique passive output attenuators provide distortion-free gain reduction without reducing the dynamic range of the converter. The attenuators optimize the gain staging between the DAC2 D and the power amplifier. This optimization is absolutely essential for maximizing the dynamic range of the entire playback system. Much of the success of the DAC1 converters can be attributed to the passive output attenuators. Musical details can be obscured by system noise whenever a preamplifier and power amplifier are improperly matched. The" HGC " system will make full use of your power amplifier's dynamic range. Experience new details in your favorite recordings.

      Native DSD Conversion
      All digital inputs on the DAC2 D support native DSD conversion. DoP 1.0 is automatically detected on all digital inputs, and the system seamlessly switches to native DSD conversion. DoP 1.0 is supported by many media players, and DSD downloads are now available from several sources.

      UltraLock2™ Jitter Attenuation System
      UltraLock2™ is an improved version of the UltraLock™ system used in the DAC1 and ADC1 product families. DSP processing is 32-bits, DSP headroom is 3.5 dB, sample rate is 211 kHz, and jitter-induced distortion and noise is at least 140 dB below the level of the music - well below the threshold of hearing. Benchmark's UltraLock2™ system eliminates all audible jitter artifacts.

      High Headroom DSP - with 3.5 dB "Excess" Digital Headroom
      All of the digital processing in the DAC2 D is designed to handle signals as high as +3.5 dBFS. Most digital systems clip signals that exceed 0 dBFS. The 0 dBFS limitation seems reasonable, as 0 dBFS is the highest sinusoidal signal level that can be represented in a digital system. However, a detailed investigation of the mathematics of PCM digital systems will reveal that inter-sample peaks may reach levels slightly higher than +3 dBFS while individual samples never exceed 0 dBFS. These inter-sample overs are common in commercial releases, and are of no consequence in a PCM system until they reach an interpolation process. But, for a variety of reasons, virtually all audio D/A converters use an interpolation process. The interpolation process is absolutely necessary to achieve 24-bit state-of-the art conversion performance. Unfortunately, inter-sample overs cause clipping in most interpolators. This clipping produces distortion products that are non-harmonic and non-musical . We believe these broadband distortion products often add a harshness or false high-frequency sparkle to digital reproduction. The DAC2 D avoids these problems by maintaining at least 3.5 dB of headroom in the entire conversion system. We believe this added headroom is a groundbreaking improvement.
