Berkeley Audio Design – Alpha DAC Series 2

Product Description

Berkeley Audio Design – Alpha DAC Series 2

The Alpha DAC Series 2 employs new clocking and isolation technologies that provide enhanced imaging precision,
timbrel purity and resolution.
Unequaled interpolation technology up-samples 44.1kHz CD’s to provide almost 176.4kHz quality and
produces superb fidelity at all sampling rates from 32kHz to 192kHz
IR remote control of all functions including volume and balance allows direct connection to power amplifiers
Advanced input signal jitter rejection

Controls & Indicators

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
