Audio Research DAC8

Audio Research's newest DAC features inputs for both high resolution S/PDIF and USB 2.0 HS audio, consequently the DAC8 is capable of reproducing music at higher definition/resolution up to 24/192kHz (DAC8 HD drivers required and included).


Features

  • The DAC8 employs four 24-bit D/A converters. Each channel uses dual 24-bit D/A converters running in mono mode to lower the noise floor and increase the dynamic range
  • Two low jitter master oscillators; one for 44.1, 88.2 & 176.4kHz sample rates and the other for 48, 96 & 192 kHz sample rates. The DAC8 automatically selects the correct master oscillator the instant digital music is detected at the selected input
  • All inputs are galvanically isolated from the source to reduce or eliminate noise and/or jitter from entering the DAC8
  • The output stage in the DAC8 have received the same attention to detail as the digital section. Each channel of the DAC8 uses a true direct-coupled differential amplifier with a bandwidth in excess of 90kHz
  • Fully balanced, zero-feedback, solid-state design utilizing a direct-coupled FET output stage with generous regulated power supplies and seven stages of regulation
  • Separate digital and audio power transformers
  • The DAC8’s USB and S/PDIF inputs are designed to accept signals from an HRx, 176.4kHz, 24-bit, High-Resolution music server system playing HRx’s DVD-R recordings
