The 88D Monitor Panel provides full control over surround monitoring.
How the Surround Sound system works
A surround sound set up on the 88D consists of three main parts:
Signal sources that are panned.
Film stems that accept the panned signals.
Film monitoring that controls which stems are output to the speakers.
The signal sources are inputs that are routed to Channels. Panning is always
available on a Channel, its effect depends on the pan designators applied to the
paths (Tracks or Groups) that the Channel is routed to.
Stems are made up of Tracks that have had suitable pan designators applied to them
using Desk Edit or Surround Manager in Encore. The pan designator means that
when a Channel is routed to a particular Track then the Track only receives the
relevant portion of the signal that is panned to the speaker position indicated by the
pan designator. This gives the mixer detailed control over how signals are panned to
multiple surround destinations.
The Simplified Surround Monitoring diagram shows how this works:
5.1 Format Surround Sound Example
A 5.1 Format Surround Sound set up on Stem A is used as an example in this
chapter. This is a very simple set up for illustration purposes only.
This format is known as 5.1 because there are five surround destinations (Front
Left, Front Centre, Front Right, Rear Surround Left and Rear Surround Right)
plus the sub-woofer.
The set up will be as follows:
5.1 Format Surround Sound using FL, FC, FR, SL, SR and SW (sub-woofer).
Tracks 1 to 6 will form Stem A.
Channel 10 as a stereo input from 1lin 1AB.
Channels 11 and 12 as mono inputs 1lin 2A and 1lin 2B.
Channels are on layer A, Tracks are on layer B and Film Mons are on layer D.
All the parts of this example refer to this set up and the steps towards obtaining
it. It is assumed an appropriate Desk Setup with enough Channel, Track (bus)
and Film paths has been loaded. It is also assumed that the Films are patched
to the correct outputs for the speakers (the particular outputs used for the
speakers will be different from one 88D to another).
