Sonifex RB-DDA22 | Digital Audio Distribution Amplifier With Multiple Outputs

The RB-DDA22 is a digital audio distribution amplifier with multiple inputs and outputs. It accepts one of five different digital input formats and provides 22 outputs across five different connector types. The unit is used for distributing digital audio data in multiple formats, repeating both the audio and the input status information while re-clocking the data and normalising it to the appropriate standard digital audio levels. 1 x XLR 3 female AES/EBU digital audio input
