• 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.

• 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
