Studio Outputs & Foldback Masters
Studio Outputs
1
The signal level available at the Studio Speakers Output jacks on the rearcon
panel is controlled by the C/RM TO STUDIO SPKRS pot. The input to this control
is taken from the source selector switches on the Control-room Speakers/Phones
Panel.
When the Talkback-to-Speakers signal (from the Talkback Panel) is present, the
normal signal is dimmed and the Talkback signal is superimposed. The level of the
Talkback signal is not affected by the setting of the C/RM TO STUDIO SPKRS
control, it is set by the GAIN control on the TALKBACK Panel.
2
The signal level available at the Studio Headphones Output jacks on the rearcon
panel is controlled by the C/RM TO PHNS pot. The input to this control is taken
from the source selector switches on the Control-room Speakers/Phones Panel.
3
The FB1 switch adds in the Foldback 1 post-fade signal to the Studio Phones
post-pot signal (both Left and Right signals of the Headphone stereo image).
4
Similarly, the FB2 switch adds in the Foldback 2 signal to the post-pot signal.
Both of these switches, FB1 and FB2, may be depressed at the same time. If,
however the STEREO switch on the Foldback panel is depressed then the FB1
signal is only sent to the Left channel, whilst the FB2 signal is only sent to the Right
channel.
5
These signals are then passed through the STUDIO PHNS level control.
When the Talkback-to-Phones signal (from the Talkback Panel) is present, the
normal signal is dimmed and the Talkback signal is superimposed. The level of the
Talkback signal is not affected by the setting of the STUDIO PHNS control, it is set
by the GAIN control on the TALKBACK Panel.
6
The AFL switch sends a mono (L+R) signal to the PFL/AFL circuit of the
Control-room Monitor. Its associated LED indicates when the switch is depressed.
Foldback Masters
The Foldback system has 2 channels: FB1 and FB2. These are controlled by the
section described below.
The Foldback Master section receives inputs from two Module types: the Input
Modules and the Stereo Input Modules.
Signals from Input Modules

The FB1 signal is switchable between the Channel and the Monitor path. The
switching is done by the CH/MON switch. The level of the FB1 signal from each
Input Module is controlled by the FB1/L CH/MON pot on each Input Module.
The FB2 signal is always connected to the Monitor path, its level from each Input
Module is controlled by the FB2/R MON pot on each Input Module.
Both of the FB1 and FB2 signals described above are available pre-fade or post-fade
