7106 Quad Panning module 6-7
Revision J2005-2 J-Type
916 :439# 4XDG # 3DQQLQJ # PRGXOH
The Quad Panning module has two line level inputs with on/off, OSC/PNG bus and
an input level control.
If both inputs are ‘off’ (switches up), then Input A is selected by default.
If Input B is ‘on’, but Input A is ‘off’, then Input B is selected.
If both inputs are selected ‘on’ at the same time, the signals are mixed relative to the
settings of the input level controls.
The AUX VCA button in the fader below the Quad Panning module also operates the
Input B switch. This means that if the Input A and Input B switches are set ‘off’ on the
module, the AUX VCA button will allow you to switch between inputs A and B manu-
ally or under computer control, since the AUX VCA button can be programmed as
part of a cue.
An insert Send and Return break jack facility is incorporated, so that an external pro-
cessing unit can be inserted in the signal path, and the module is designed to use a
standard VCA fader (mounted in the fader well), as its overall level control.
After the fader, the signal is passed to a quadraphonic pan-pot. Four fully buffered
outputs are derived, each having an output level control. The four outputs are
labelled:
Front Left
Front Right
Back Left
Back Right
A width control allows you to adjust the relative separation between the outputs.
Width set to MAX:
As the quadraphonic pan-pot is moved from one ‘corner’ to another (say FL to FR),
the output disappears from the first position, when the signal is fully panned to the
second position.
Width set to MIN:
In this case, although the output pan’s from the first to the second position, a small
amount of signal is still present at the first position.
Thus, by varying the width control, it is possible to adjust the overall ‘image’ position
of the signal, to suit the incoming program material.
Additionally, each of the four outputs can be routed to any of the Matrix Groups avail-
able on the console, via four banks of rotary switches.
Comprehensive muting facilities are provide for each output and Matrix routing selec-
tions.
