Alpha DAC Series 3 - A Breakthrough In Audio Quality And Value

  • The Alpha DAC Series 3 uses advanced technology from the award-winning Alpha DAC Reference Series 3 to provide sonic excellence never before possible at anywhere close to the price of the Alpha DAC Series 3.

  • Compare the Alpha DAC Series 3 and Alpha USB noise isolation interface to any DAC at any price and be amazed by their superior audio quality.

  • The Alpha DAC Series 3 replaces the Alpha DAC Series 2. However audio quality and technology are much closer to an Alpha DAC Reference Series 3. The Alpha DAC Series 3 includes MQA Rendering capability.

  • Excellent PCM audio quality from 32kHz to 192kHz

  • Excellent MQA Rendering quality to beyond 384kHz

  • Ultra-low phase noise conversion clocking

  • Outputs can connect directly to power amplifiers

  • All metal Series 3 IR Remote Control

Controls & Indicators

  • Input selects AES, SPDIF1, SPDIF2 or Toslink inputs

  • Lock LED indicates input signal lock

  • HDCD LED indicates HDCD code detected

  • Phase sets absolute phase

  • Invert LED indicates absolute phase inverted

  • 3 digit LED display of Stereo/L/R attenuation, Sampling Rate and Filter type

  • ± controls set attenuation level and select Filter type

  • Mode selects Stereo/L/R attenuation, Sampling Rate and Filter type display modes

  • Dim selects multiple display brightness levels
