Composite Output 1 & 2
These controls individually set the level at the two separately buffered rear-panel composite outputs. The
output level adjustment range is between 1.25 and 9.5 volts peak-peak. Use the jog-wheel to select the
modulation level for each composite output. Once the desired peak modulation level is displayed, click the
jog-wheel to set the level and return to Highlight Mode.
Always use typical program material and a calibrated modulation monitor to properly set modulation. To
aid quick adjustment, it sometimes helps to advance the Clipping control before adjusting the composite
outputs. Note that reference line-up tones applied at the Omnia6-fm input cannot be used since the RMS
level of a steady state tone does not crest at 100% modulation.
SCA Level
Sets the SCA subcarrier deviation level. This adjustment should always be done using a calibrated
modulation monitor.
Note: Adjusting the Composite Outputs changes the SCA deviation level since the two output controls are
effectively in series. Always recheck the SCA Level adjustment after making adjustments to the Composite
outputs.
Pilot Injection
Sets the pilot level from 6% to 12%, in 0.1% steps, relative to 100% modulation. To defeat the pilot, simply
adjust the Pilot Injection control below 6% and the control indicates Off.
