Sonifex 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.

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.
