A/B Feed from an External Source
The A/B program output can be created from an external source (such as a DAW).
To use an external A/B source, use the following procedure:
1.
Patch the outputs of the external source to the A/B Master Fader input (A/B
SURROUND FADER IN) patch points
In this scenario, the A/B Surround Master Fader is fed from the external source.
The output of the A/B Master Fader is fed to its associated booster and output to
the SURROUND FEED to the 8Track surround mix recorders and Control Room
Monitors (if 5.1 PGM is selected as the monitor source).
7.5 5.1 and 7.1 Master Faders
Although all Vision consoles have only five (5) surround program mix busses and ACAs, each
console is fully equipped with either 5.1 or 7.1 Surround Master Faders and surround program
outputs.
The Surround Master Faders may be fitted in one of two configurations:
•
5.1 with 5.1 Control Master Fader
•
7.1 with A/B Master Fader
The 5.1 Master Fader package has audio Master Faders for the Left/Right, Center, LFE, Left
Surround/Right Surround Busses. The last fader is a 5.1 Control Group Master (5.1). An A/B
Master Fader is not included in this configuration.
The 7.1 configuration is the same as 5.1 except a console configured for 7.1 mixing will have an
audio master fader for the A/B Surround Program. A 5.1 Control Group Master Fader is not
included in this configuration.
NOTE: One of the six (6) Control Group Master Faders may be assigned to the 7.1 Program
Master Faders if a Surround Program Control Group Master is needed.
On a console configured for 5.1 mixing, there are four (4) Master Faders that support the six (6)
5.1 Surround Program outputs and a 5.1 Control Group Master Fader.
The 5.1 Surround Program outputs are assigned to a Master Fader in the following groupings:
•
L/R: Left and Right
•
C: Center
•
LFE: LFE
•
SUR: Left Surround and Right Surround (SUR)
•
5.1: 5.1 (Surround Control Group Master Fader)
A 5.1 Group Master Fader is installed where the A/B Master Fader is located in a 7.1 configuration.
This 5.1 Group Master Fader is a control device only and does not pass audio. It controls the L/R,
C, LFE, and SUR Master Faders for surround program fades.
