Operation
Model GEN-DDA/WC
In the event of an external AES/EBU signal failure to either input section, the unit automatically
switches to a high precision internal signal generator. Front panel indication and selection of the
stand-by internal sample frequency is provided. The internal precision generator may be selected to
generate clocks in lieu of the external AES/EBU input.
Push the “INT” front panel switch to select the internal sync generator. Select any sample rate.
In addition, audio that appears with an AES/EBU input will be distributed to the AES/EBU outputs if
the AES/EBU input is selected as the generator source.
An external Word-Clock signal input is provided, buffered and distributed to six independent outputs.
In the event of external source failure, or at the user’s option, a frame-clock reference signal,
selectable from either of the two AES/EBU inputs is regenerated and output to the Word Clock
outputs.
Model DDA/WC-4x4
An external Word Clock signal input is provided, buffered and distributed to six independent outputs.
In the event of external source failure, or at the user’s option, a frame-clock reference signal,
selectable from any of the four AES-EBU inputs is regenerated and output to the Word-Clock outputs.
Push and hold any operating frequency button to pre-set the switch-over sample rate in the event of
an external reference failure.
