EXPLANATION OF CONTROL
The INPUT controls adjust the input signal levels. The SETUP controls adjust
the gains of the photocell monitor amplifiers which are DC coupled. The gain is
set so that when the SORS unit is in the SETUP mode the front panel digital
meters read the standby or "slack" ribbon spacing in mils. This standby track
spacing may be verified by developing a strip of film exposed with the SORS in
the SETUP position and measuring the track dimensions with a microscope. The
BIAS control adjusts the gain of the output drive amplifier of the SORS whose
output is the composite of the audio and noise reduction signals. In the BIAS
mode only the noise reduction signal is present, and the ten turn BIAS controls
may be adjusted to provide the desired size bias lines.
The Mono/Stereo toggle switch does two things. It selects the audio input to
the SORS from either the two stereo inputs or the monaural input and it selects
the proper track placement and spacing required for the two different recording
modes.
