DacMagic Technical Specification - Cambridge Audio

Cambridge Audio DacMagic
• 2 digital inputs featuring both optical & coaxial
connections for each, plus an additional USB
audio input.
• Balanced XLR and unbalanced RCA audio
outputs
• ATF (Adaptive Time Filtering) up-sampling
intelligently interpolates incoming audio data
(16-24 bits, 32-96kHz) to 24bit/192kHz output
through the use of a 32bit Texas Instruments DSP
• Twin Wolfson WM8740 24bit DACs used in dual
differential configuration.
Detailed Specifications

Audio Outputs
• Selectable digital filters (Linear Phase,
Minimum Phase and Steep) differ slightly in
optimisation and allow user to select filter of
their choice.
• USB audio input allows the DacMagic to act
as a high quality DAC/soundcard for your
computer
• Digital output provides ‘pass-through’ output
to recording devices.
• Available in black or silver finishes
