RB-DAC1

Digital to Analogue Converter

Using 24 bit, 192kHz capable devices, the RB-DAC1 D/A Converter is a 1U rack-mount which produces a stereo balanced XLR or unbalanced phono output from an incoming AES/EBU or S/PDIF digital input signal.

RB-DAC1

Digital to Analogue Converter

Using 24 bit, 192kHz capable devices, the RB-DAC1 D/A Converter is a 1U rack-mount which produces a stereo balanced XLR or unbalanced phono output from an incoming AES/EBU or S/PDIF digital input signal. There is also a headphone output with volume control for monitoring purposes.

The analogue outputs have an output level control, allowing full-scale settings selectable from +12dBu, +18dBu or +24dBu. The RCA phono outputs have a further 8.5dBu attenuation incorporated.

There is a button to select either the AES/EBU or S/PDIF input for the D/A converter, which is located on the rear panel. Additionally, if de-emphasis is selected, the RB-DAC1 will decode 50/15µs emphasis when indicated by certain channel status bits in the incoming digital audio data.

When operating, the front panel power LED flashes whenever the unit is not synchronised to the incoming digital signal.

Product Features

  • AES/EBU & S/PDIF digital inputs.

  • Balanced XLR and phono analogue outputs.

  • Headphones output with level control.

  • Switchable de-emphasis decode.

Typical Applications

To connect the output of a CD player to an analogue amplifier, or the program output of a digital mixer to a pair of powered speakers.
