Midas HERITAGE 2000 Operator's Manual page 17

The PAN defaults to control the channel
placement within a group or master
stereo mix and has a constant power law
i.e. - 3dB at the centre position.
The SIS switch enables the spacial
imaging system which operates in
conjunction with the pan and image
controls. It also acts as a left, centre, right
master bus enable overriding any stereo
and mono master bus assignments.
When the spacial imaging system is
active the IMAGE control can modify
the action of the pan control so as to
place the channel within a three speaker
system. When the image control is fully
clockwise the pan control will operate
in full left, centre, right such that a centre
panned signal will route to the centre
speaker only and will not appear in
either of the left or right outputs. When
the image control is fully anti-clockwise
the pan control reverts to stereo such that
a centre panned signal will route at equal
power to the left and right speakers. All
other Image control positions generate a
composite blend of the stereo and LCR
panning systems so that the optimum
degree of center image focus and
speaker power can be obtained. When
the image control and pan control are
both set central the channel will be
routed with equal power to all three
speakers. Constant power is maintained
at all times so that the image can be
adjusted during the show without any
perceived level change.

The ST switch connects the post fader
channel signal to the master stereo bus
via the pan control.
The MONO switch connects the post
fader channel signal to the mono
master bus.
The METER monitors the peak signal
level of the pre fader input channel.
The MUTE switch mutes the input
channel at all points after the insert send.
The switch can be controlled from
snapshot automation and by automute
scenes.
