Nuoptix Stereo Optical Recording System, Owner'S Manual

Page: 8 / 38

OPERATION
Before turning the system on or off the front panel mode switch should be set
to the SETUP position. This electrically disconnects the light valve from the
electronics and thereby protects it from electrical transients. The system is
turned on by the power switch on the front of the AOS. To record an optical
track, first set the record lamp current and select MONO or STEREO mode with
the SORS front panel toggle switch. (Note that the lamp current may be reduced
when not recording by toggling the lamp standby switch to the standby position.
The reduced lamp current prolongs lamp life.) With the mode switch in the
SETUP position adjust the SETUP pot controls on the front panel to read the
slack light valve ribbon spacing (in mils) for the particular light valve in use.
Rotate the mode switch to the BIAS position and adjust the two 10 turn controls
labeled BIAS to provide the desired size bias lines as indicated on the digital
meters. A 1.5 mil bias line for stereo recording and a 2.0 mil. bias line for
monoaural recording is recommended. Note that different BIAS settings will be
required for stereo and mono recording. Rotate the mode switch to the RECORD
position and adjust the input bus level signal to read 50% using the INPUT level
controls. The SORS will accept input bus levels from -10 dbm to +10 dbm. Prior
