Word Clock Outputs (QA-9 Pro only)

To enable the word clock outputs at the rate

indicated on the front panel display, set the switch

to the position labeled “WCk En”. Switch position

“WCk Dis” will turn all the word clock outputs off.

DSD Output (QA-9 Pro only)

Three of the BNC output connectors can be

configured to output digital audio data in the

professional SDIF-2 or SDIF-3 DSD format. To

enable the 3-wire DSD output set the switch to

“DSD En”.

Enabling he DSD output

overrides the word clock output

settings for the three shared

BNC connectors and forces the

fourth to 44.1 kHz.

The front panel display will indicate “DSD” mode

with a red LED to the left of the numeric display.

The numeric display will then indicate the DSD

output rate, e.g., “128” (signifying the multiple of

the 44.1 kHz CD rate), as set by the three sample

rate selection switches in the table below:
