microprocessor muting system
features
channel mute controls
J—STATUS LED
This bi-color
LED, associated with each controlled-mute, shows the con-
dition of that mute.
One-of-five possible states is possible:
1
OFF—The channel is not controlled by the
MUTE CONTROLLER
.
2
STEADY RED
—The channel is being muted by a MUTE SCENE.
3
STEADY GREEN—The channel is in SAFE MODE, cannot be muted by any
scene.
4
FLASHING RED—The system is in EDIT/PREVIEW mode and the channel
is in the currently selected
SCENE.
5
FLASHING GREEN
—The system is in
EDIT SAFE mode and the channel is
included in the
SAFE SCENE.
6
MUTE SWITCH
—This momentary-switch toggles the channel’s
LOCAL
MUTE
and is also used to assign/un-assign channels to MUTE and SAFE SCENES,
when in the
EDIT mode.
7
MUTE LED—This internal red-LED will illuminate whenever the channel
is muted, either locally or by a
MUTE SCENE.
If a channel is already locally muted when a relevant
MUTE SCENE is activat-
ed, this
LED will remain lit.Two sources are now telling the channel to
mute:the
LOCAL MUTE and the MUTE SCENE. If the MUTE switch K is pressed
once, the
LOCAL MUTE
will be cleared, but no apparent change will occur.
The
MUTE LED L will still be lit, and the STATUS LED J will still be steady-red.
At this point there is only one source telling the channel to mute;the
MUTE
SCENE
. If the MUTE SCENE
is then disabled, the channel will un-mute because
the
LOCAL MUTE was previously cleared.
The user should be aware of this fact—the local mutes can toggle invisibly
behind a
MUTE SCENE. For an even number of presses on the MUTE switch
K,the
LOCAL MUTE will return to its original state,an odd-number of press-
es will change the
LOCAL MUTE to its opposite-state.
