Chapter 11: Panning

The PRO Series Control Centre has two main types of panning mode, default and
surround. The default mode comprises stereo and LCR panning formats, and only uses
the channels for the front loudspeakers, while the surround mode includes channels for
the rear surround loudspeakers.
The following table shows the panning formats available on the PRO Series.

Stereo panning

The control surface controls for stereo
panning are located in the masters
section of each input fast strip and each
channel strip.
The pan control associated with the
masters section may be switched for
either conventional or spatial imaging
system (SIS™) stereo operation by
using the ST or SIS switches,
respectively.
SIS™ (LCR) mode
The Midas SIS™, which is used for left-centre-right (LCR) loudspeaker systems,
configures the channel for LCR mixing. The SIS switch activates the spatial imaging
system, which uses the SIS image control knob to modify pan control knob operation
so as to place the channel within a three-speaker system.
With the SIS image control knob set fully clockwise or anti-clockwise the image is full
LCR or stereo, respectively. Control knob positions in between generate a composite
blend of stereo or LCR panning systems, so that optimum degrees of centre image
focus and speaker power can be obtained. This is illustrated in the following
subsections, which shows the masters section in the channel strip.
