3.4.2.2. CM: INTNL SOUND section
• IS SOURCE There are two available International Sound connections, IS1
and IS2. Only one of them can be connected at a time to the control module.
The selected one may be sent to the Commentary Unit and is then mixed
with the PRG (program) signal to form the composed PRG that is sent to the
IBC.
• IS MIX ENABLE. This switch, when activated, enables the selected
international sound to be mixed with the program. It does not effect the IS
send to the headphones of the commentators at the associated CU which is
always available.
NOTE: The IS MIX ENABLE blinks when, from a CU programmed to use the
TAPE CHANNEL ON as IS control, IS has been deactivated : because
CHANNEL TAPE is used to send its source to program or because that
switch has been used to deactivate IS. When CHANNEL TAPE is broken
(deactivating CHANNEL ON), the IS that was broken will be restored.
• MIX. LEVEL. Controls the mix level
of IS signal with PRG. The mixed
program is formed composing the
PRG (program) feed, coming from
the Commentary Unit,
selected International Sound (IS).
The IS signal is also previously
processed by an DLP (Dynamic
level processor) algorithm, which
can be software configured. The IS
input level is controlled by means of
a rotary potentiometer. This control
acts
processed and incorporated at a
fixed program level.
