sonifex rb dda6w 2p 1

The Sonifex RB-DDA6W-2P word clock distribution amplifier distributes a word clock BNC input signal to 6-word clock BNC outputs re-conditioned. It is used to distribute reference clocks for digital audio systems.
It has a single female BNC audio input which is distributed to 6 female BNC outputs. The units primary application is to distribute a master TTL word clock source to multiple pieces of equipment that need to be synchronised from the master.

The unit provides redundancy protection by using two power supply units that can be supplied from separate mains feeds. The unit automatically load shares between the two supplies so that if either supply should fail the unit will continue to work correctly. If both supplies fail the input is connected directly to output 1.

The condition of the two supplies is indicated on the front panel by two red LEDs which illuminate to indicate the correct function of the supply. On the alarm output connector, there is a changeover relay to indicate the status of each supply. This is normally closed to indicate power fail and once the supply is working correctly the relay activates to make a normally open contact.
