Communications

Talkback level controls are fitted on the SL953 panel, to the right of the main output
compressor (see opposite). In addition to a built-in talkback microphone, the controls
set the level of talkback to the studio loudspeakers (TB to SLS) and headphones (TB to
Foldback), Slate Level and incoming Listen Mic levels. The talkback microphone is
fitted flush into the control surface next to the TB to Foldback level control.
TB to Foldback and TB to SLS – These controls set the level of talkback to the
Foldback (A, B and C) and the SLS (Studio Loudspeakers) outputs. Note that talkback
is inserted after the Foldback and SLS level controls (see Page 5-13).
Slate Level – This control allows the level of talkback to tape to be adjusted. A low
level 30Hz tone is added to the slate signal so that an ident may be easily located at
high tape wind speeds.
Listen 1 and 2 – The Listen Mic gain controls have integral pull-for-off switches. Two
listen mics can be placed in the studio and connected to the console's Listen Mic
Inputs. These feed up to the patch and appear at N&P 41-42. The mic signals are
mixed together via the level controls and fed to a compressor (more on this below).
The group of COMMUNICATIONS buttons (to the left of the Main Fader – see
opposite) controls the switching and routing of Talkback and Listen Mic signals, as
well as the switching of a Red Light.
RED LIGHT – Provides an isolated contact closure for hooking up to a studio red
light or transmission light via an external relay box. When the AUTO CUE button is
on (see below), the red light can be activated automatically when the multitrack goes
into Record. (Internal links can be set to select this option from machine Play or
Record).
CUE LIGHT – Provides an additional isolated relay closure for hooking up to studio
cue lights etc.
SLATE – Cuts all loudspeakers and feeds the talkback mic to multitrack busses 1-48,
Main output busses, Foldback sends and Studio Loudspeakers. A low level 30Hz tone
is mixed in with the signal to tape so that the slate may be easily located at high wind
speeds.
EXT T/B – Provides switched talkback which appears on the patchbay at N44, for use
as an additional talkback send to the studio floor, the machine room or anywhere else
you fancy!
