The RB-DDA6A-2P digital distribution amplifier is used for distributing digital audio data in AES/EBU format, repeating both the audio data and the status information of the input whilst re-normalising to standard digital audio levels. It has a single XLR-3 female AES/EBU audio input which is distributed to 6 XLR-3 male AES/EBU outputs. 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 can accept input sample rates in the range of 30kHz – 100kHz, and bit rates of 16, 20 and 24 bit. So, it can be used for standard signal distribution at 16 bit 44.1kHz, as well as for high quality 24 bit 96kHz recording. The unit provides redundancy protection by using two power supply units that can be supplied from separate mains feeds. The unit features dual power supplies with automatic load sharing, ensuring continuous operation if either supply fails. The status of each supply is indicated on the front panel by two red LEDs, which illuminate when the supply is functioning correctly. Additionally, the alarm output connector includes a changeover relay to indicate the status of each supply. The relay is normally closed to signal a power failure and switches to a normally open contact when the supply is operating correctly. 1x XLR AES/EBU digital audio input.
