A/B Feed from Fader 2 and a Pair of Multitrack Summing Busses
Feeding the A/B program outputs from Fader 2 provides an A/B feed that follows
the Fader 2 moves, without an independent level control.
To create an A/B feed from Fader 1 and a Multitrack Summing Bus, use the
following procedure:
1.
Patch the output of a pair of Multitrack Summing Busses (BUS OUT) to the
A/B Master Fader input (A/B SURROUND FADER IN) patch points
2.
Make sure the Multitrack Summing Bus Trims are turned on and turned up
3.
Assign Fader 2 to the selected Multitrack Summing Bus on the desired
channels
The diagram below shows the routing for Fader 2 feeding an A-B feed from
Multitrack Summing Busses 5-6 and a LFE feed from Multitrack Summing Bus 1.
In this scenario, Fader 2 is
assigned to feed Multitrack
Summing Bus 1, which feeds
the LFE Filter. The output of
the LFE Filter feeds the LFE
Surround Master Fader.
Fader 2 is also assigned to
feed Multitrack Summing
Busses 5 and 6, which feeds
the A/B Surround Master
Fader. The Pan-pot is also
engaged on these channels
to facilitate panning between
the 5 and 6 busses (A and B
channels).
The Master Faders feed the
associated boosters and
outputs to the SURROUND
FEED to the 8Track surround
mix recorders and Control
Room Monitors (if 5.1 PGM is
selected as the monitor
source).
Fader 1 can be fed from the
Fader 1 output by engaging
the FDR1 switch on the
desired channels. This allows
Fader 2 to be used as an
automated LFE send.
If Fader 2 is also feeding the
5-channel Surround Program
Bus, the A/B and LFE feed
will be proportionate to the
5-channel program feed.
The LFE Filter is bypassed in
the Control Room monitor
system.
NOTE:
With the LFE bypassed in the
Control Room monitors as
described above, Bass
Management will not be
active when monitoring
Surround Playback sources.
