Stem and Recorder Control Section
The Stem and Recorder Control section has two main functions: Stem configuration and recorder control.
Stem Configuration
The Stem Control Panel is used to configure up to six Stems, labelled A through F. Each Stem can consist of up to
eight Tracks (busses) which are then routed to the Film paths in conjunction with the Surround Monitoring panel.
Each Track in each Stem also has Solo and Cut control. This only affects the signals routed to the Film paths and
is the same as using AFL Solo and Cut on the corresponding fader strips.
Recorder Control
The Stem Control Panel can be used to control the Record status of Mag and Multitrack tape machines.
Bus/Tape switching is provided to allow monitoring of the Track Send (Bus) or Track Return (Tape).
An array of tally LEDs indicates the record status with red letters which correspond to the Stems. Green LEDs next
to each letter show the Bus/Tape switching.
A safe mechanism is provided which operates internally to disable Record on individual Tracks and prevent
further Record enable commands being sent to the tape machines for the safe Tracks.
Fully configurable master control grouping can also be used for Record, Bus/Tape and Safe.
Using Recorder Control
Requirements
A relay control unit must be installed: either a Relay Control Unit (also known as a Fader Start Box) or a Recorder
Interface Unit.
An I/O configuration must be loaded that associates the output ports on Track Sends with the correct relays. This
can only be configured using I/O Patching.
Both multitrack and mag machines must be in play for REC enable to be possible.
Relay Control Unit
The Relay Control Unit can control either multitrack or mag machines.
For multitrack machines there are 48 record enable relays and tally inputs.
For mag machines there are 32 record enable relays and tally inputs.
The Logic MMC Installation manual provided with the system will have details of the connections that are made
to the Relay Control Unit.
Recorder Interface Unit
This is an updated version of the Relay Control Unit that provides relay connections to both mag and multitrack
tape machines.
The Recorder Interface Unit has 96 record enable relays: 48 for mag machines (dubbers) and 48 for multitrack
machines. There are also 8 Master Control relays for multitrack machines. There are corresponding tally inputs
for the record enable relays.
The Recorder Interface Unit User Guide has details of the connections that are made to the unit.
