The silence detect interval DIPSwitches adjust the duration over
which a silence is detected before alarming which ranges from
2-252 seconds (by adding together the raised DIPSwitches, in
2 second intervals). If all the DIPSwitches are down, (off) the
duration defaults to 30 seconds. This can be changed using the
SCi serial software.
Serial Mode Setting
To activate serial mode, set DIPSwitch 8 on (up). When activated, the serial mode LED
illuminates on the front panel (see Fig 10-3) and the unit can be controlled serially instead of
from the front panel controls, using the SCi software.

The trigger level DIPSwitches adjust the level below which
silence detection occurs. This level may be varied from -39dBFS
to -84dBFS in 3db steps by summing DIPSwitches that are on and
adding -39dBFS. 0 (all off) represents -39 dBFS.
Stereo/Mono Selection
The configuration of this defines whether you want to switch
sources when the left and/or right channel of the incoming source
go silent.

Description
On
When on, the unit operates in stereo mode,
whereby if one channel goes quiet the unit will
switch, and requires both channels to be present
before it switches back.

When off, the unit operates in mono mode. In
this mode the unit will only switch when both
channels go quiet, and requires only one channel
to be present before the unit switches back.
