Master Section: Monitoring & Control

Monitor Section

The dedicated Monitor Section allows the user to listen to and view the various signals operating within
the Console.

This section consists of: the monitor select circuitry and dual LED meters, the Solo  system and head-
phones.

Monitor Metering 

Two LED meters, L & R, are provided to display the level of the Monitor source.These meters are cali-
brated to properly display the internal levels within the console.The 0VU point is the nominal operating
level of whatever signal is being Monitored. If more than one source is selected, the meters will display the
level of those mixed sources.

Source Select Switches

The operator can choose which signals to listen to and view by using the Source Select switches.These
switches select the Pre-Fader source of these seven sets of signals:

Tape B input, Mono bus, L-R buses, Groups 1-2, Groups 3-4, Groups 5-6, Groups 7-8

The Monitor System circuitry is stereo, and these are all stereo sources except for the Mono bus.These 7
signals can be combined by selecting more than one source.All sources that are selected will be equally
mixed together.This combined signal is then displayed on the Monitor LED meters, and fed to the
Monitor Level pot and to the headphone system.

This level pot feeds the Monitor Output jacks (1/4” TRS) on the rear panel. It does NOT affect the

level of the headphone feed or the LED meters.

Sum Mono

A Sum Mono switch is provided which mixes the L & R monitor rear-panel outputs together.This switch
is useful if feeding a single external monitor speaker.The LED meters and headphones are not affected by
this Sum switch.

Solo Off

Normally, the Monitor system will be interrupted by the Solo System. If a Solo button is pressed (PFL or
AFL), the Solo LED between the meters is illuminated and the Solo signal is displayed on the LED meters.
The Solo audio takes the place of the selected Monitor sources for both the Monitor outputs and the
headphones.

If the Solo Off button is depressed, the meters and headphones will still switch over, however the Monitor
Outputs WILL NOT be interrupted by the Solo.This allows the Monitor Output jacks to be used as an
additional output for any of the 7 available sources or their mixture. Since the sources feeding the Monitor
section are Pre-fader, this additional output is controlled only by the Monitor Level pot, and is independent
of any of the main fader settings.
