3.5 Analog Master Section
The Analog Master section of the Digital Master module controls most of the master
analog outputs of the console. The Analog Master incorporates the following functions:
• Internal Oscillator Selection, Level and Assignment
• The Aux Send Master Output Levels
• The Communications Mic Level
• The Studio Monitor Level and Source Controls
• Stereo Meter Source Selection
• The Control Room Level and Source Controls
• The Stereo Master Fader
3.5.1 Oscillator
The Oscillator Section controls the operation of the console’s internal Sine Wave
Oscillator. The Oscillator provides test tones for calibrating the console’s internal levels
and the levels of devices connected to the console. The Oscillator Section has an output
point on the patchbay that allows the oscillator to be patched to any input for
troubleshooting purposes.
■
Level
The
Level
Control adjusts the oscillator output level.
■
Bus
Pressing the
Bus
button assigns the Oscillator output to the Track Buses and Stereo
Mix Bus. This is useful for calibrating recorders to the Track and Mix Bus outputs of the
console.
■
10K, 1K, 100
The
10K
and
1K
buttons select the frequency of the tone being output by the Oscillator.
Pressing
10K
alone selects a 10 kHz tone, Pressing 1K alone selects a 1 kHz tone.
Pressing
10K
and
1K
together selects a 100 Hz tone at the output of the Oscillator.
When
TB/Slate
is pressed, the frequency selected on the oscillator is fed to the
console’s Track and Stereo Mix outputs at a low level. When recorded on tape during a
slate, a 100 Hz tone becomes an audible “blip” when winding tape at high speeds,
making slates easier to locate.
3.5.2 Aux Masters
The Aux Masters Section controls the master output levels of Aux Sends 1 through 8.
Aux Masters can be muted by selecting the Aux Send Master Mute parameter in the
MISC section of the LCD Menu System. An Aux Send master mute is executed by
logically muting each Input Module’s Aux Send that is assigned to the Aux Send pair.
Aux Send 1/2 is configured as a Stereo send. On Aux Master 1/2, the lower knob
controls the master level of the Aux Send pair, the upper knob controls the stereo
balance of the pair.
Aux Sends 3/4, 5/6, and 7/8 are configured as Mono sends. On Aux Masters 3/4, 5/6,
and 7/8, the lower knob controls the master level of the Even numbered Aux Send, the
upper knob controls the master level of the Odd number Aux Send. Turning a Level
Control Clockwise raises the output level.
3.5.3 Talkback/Comm
The Talkback/Comm Control adjusts the Talkback Mic level into the Slate and
Communication Sections of the console. Talkback and Slate are activated by pressing
the
TB/Slate
button in the lower section of the Digital Master Module. Jumpers on the
console motherboard determine if the Talkback Mic will be fed to individual Aux Sends.
See

Send jumpers.
