In Master sync mode, switch positions 0 – 5, the digital output sample rate is simply set by,
and locked to, the internal on-board clock generator. No sync signal is used or required.
In Auto sync mode, switch positions 6– B, the digital output sample rate follows the sync
input. When the sync signal is not present the output sample rate will be set by, and locked
to, the internal on-board clock generator at a frequency determined by the switch position.
In Auto-Lock sync mode, switch position C, no output will be generated until lock is
achieved with a sync signal. The digital output sample rate now follows the sync input. If the
sync signal is removed then the output sample rate will be set by, and locked to, the internal
on-board clock generator at the closest frequency available to the previous sync input.
In Slave sync mode, switch position D, the digital output sample rate follows the sync input.
When the sync signal is not present the digital output is turned o.
Fig 3-5, also printed on the top of the unit, summarises the rotary switch settings and shows
the sample rate generated by the internal clock generator in master and auto sync modes.
