SOLO SYSTEM- MONITOR and CONTROL
When the Solo system is active (a PFL or AFL button is pressed), the Solo audio interrupts the default audio to the Headphone and
Monitor output (unless a Solo Off button is depressed). You can listen to the Solo’d signal through the monitor system and also view
the signal level on the Solo meters.
Solo (Audio) Trim Control
This rotary control will provide up to a +/-12dB variation of the audio level of the solo’d signal. This control affects only the solo
audio (listening) path and does NOT affect the level displayed on the solo meters; the meters always show the true level for accurate
signal monitoring.
Solo Trim On/Off Switch (with Red LED)
The solo system normally will operate in a calibrated mode.
With this switch depressed, the Solo Trim control will adjust the solo audio levels
over a +/-12dB range to both the Headphones and Monitor Out.
Solo Metering
When Solo is active, the output of the Solo mix amps will be displayed on the two
right-most meter arrays and the Red LED below them will illuminate. The Solo
Trim Control will not affect the meter level.
Main Metering
ProDesk is equipped with four 16-segment LED ladders. These meters normally
display the output level of the Main buses; the 0VU LED repr4dBu output
level when displaying the main outputs. Note: If Fader-Flip is active, the right-
most meter will display the Aux-6 output level instead of the Mono bus output
level. Whenever a PFL or AFL button is depressed, the 2 right-most meters are
switched to display the L & R Solo levels. When displaying Solo levels, the 0VU
LEDs of those meters represent the nominal level of the signals being monitored.
The meters are capable of displaying 3 different types of ballistic response:
Average Response : Displayed as a VU-responding bargraph (slower attack)
Peak Response : Displayed as a Peak-responding bargraph (faster attack)
Ave + Peak (Combination of both):
When both are active, Peak shows as a single LED above an Averaging bargraph.
The same decay-time is used for both to allow the Peak LED to always be visible
above the averaging bargraph.
