Sonifex RB-DAC1Digital to Analogue Converter
Using 24 bit, 96kHz 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.
Please select the variant from the product options.
