Sonifex RB-DDA6A-2P 6 Way Stereo AES/EBU Digital Distribution Amplifier with Dual Power Supplies

Digital audio data in AES/EBU format is distributed using the RB-DDA6A-2P digital distribution amplifier, which repeats the audio data as well as input status information before re-normalizing to standard digital audio levels. Six XLR-3 male AES/EBU outputs are connected to a single XLR-3 female AES/EBU audio input. Applications include distributing audio from a digital mixing desk to multiple digital recorders or feeding multiple studios with an output from a DAT machine.

It is capable of accepting input bit rates of 16, 20, and 24 bits as well as sample rates between 30 and 100 kHz. Thus, it may be utilized for both high-quality 24-bit 96kHz recording and regular CD signal distribution at 16-bit 44.1kHz. By utilizing two power supply units that can be supplied from different main sources, the equipment offers redundancy protection. For the unit to function properly even if one of the supplies fails, it automatically loads shares between the two supplies. The input is connected directly to output 1 if both supplies fail.

Two red LEDs that light to show the correct function of each supply are used to display the condition of the two supplies on the front panel. There is a changeover relay to show the status of each supply on the alarm output connector. When the supply is functioning properly, the relay activates to form a typically open contact. typically, this is closed to signal a power outage.
