CENTER SURROUND 3X
OPERATION
The CS-3X is automatic in its operation and
requires virtually no operator intervention.
Since the CS-3X format terminals are con-
nected to the Optical Processor format termi-
nals, all switching is done automatically.
There is a pushbutton which can be used to
defeat the CS-3X operation if needed and force
the unit into normal LS-RS operation. This will
not need to be done except in rare instances
where for some reason the digital soundtrack
does not decode well.
It is important to leave the CS-3X/LS-RS
pushbutton in the CS-3X position (in) at all
times unless there is a need to defeat the 3X
mode for some reason such as that mentioned
in the above paragraph. If the pushbutton is
put in the LS-RS position (out), and then
pushed back in, the 3X mode will NOT be re-
selected until the automation, digital player,
or optical processor has once again selected
the digital format.
If there is a problem with the CS-3X such as
distortion, noise, a dead channel, or some
other problem, then the operator can simply
press the POWER/BYPASS switch to the BY-
PASS position. In the BYPASS mode, the Left
Surround and Right Surround signals are fed
straight through relay contacts and on to the
amplifiers. In addition, the Rear Wall chan-
nels are fed signals from the Left Surround and
Right Surround Signals.
If the power supply in the CS-3X should fail
completely, the unit will automatically go into
BYPASS mode.
The PRESENCE LED on the front panel alerts
the operator that REAR channel material is
present on the digital soundtrack. When this
LED is on, there is program material going to
the REAR WALL speakers in the auditorium.
