Almost all other signals call for higher
HPF
frequency points (at least 80Hz). With these
signals, there isn’t much below 80Hz that you
want to hear, and filtering it out gives the low
stuff you do want much more definition.
With
HPF
, you can safely boost
LOW EQ
and
LOW-MID EQ
. Many times bass shelving
EQ
can really benefit voices. Trouble is, adding
LOW
shelving
EQ
also boosts the infrasonic de-
bris: stage rumble, mic handling clunks, wind
noise, and breath pops.
HPF
removes all that
debris so you can boost the
LOW EQ
without
frying a woofer.
CHANNEL OUTPUT CONTROLS
Now that we’ve made it through the
Channel’s input controls, we have a signal that
has been level-corrected, polarity-adjusted,
HPF
-ized, and beautifully shaded with
EQ
. It’s
ready to go out and meet the audience. The
Channel output controls offer many ways to
get this signal out of the console. Just to get a
handle on things, we’ll stick to the basic tried-
and-true methods and leave the wild routing
schemes up to you.
MUTE
Point Before:
EQ IN
switch
.
Point After: Fader
,
PRE
switch (
AUX
1–4
)
.
Muting a Channel removes the signal from
these output paths:
LEFT/RIGHT/CENTER
mixes
and
SUBS
(
SUB 1–8
mixes)
,
AUX SEND MASTERS
,
AFL SOLO
,
and
AFL
Channel Meters. The
INSERT SEND
,
PFL
SOLO
,
and
PFL
Meter paths are not affected.
Unlike the “latching” switches, which live
in an up-or-down position, the
MUTE
switch
is “momentary” — when you press it, it comes
right back up. Pressing the switch toggles the
electronic mute relay in the signal path’s cir-
cuitry. If the Channel is muted, pressing the
switch un-mutes it, and vice versa. An LED
adjacent to the switch glows when a Channel
is muted.
The reason this switch is of the momentary
persuasion is to enable you to change mute
settings by other means, namely
ULTRA
MUTE
™
. With
ULTRA MUTE
™
, up to 100
different mute groups can be configured, en-
abling you to mute several signals at once. Not
only that, but you can automate the muting of
Channels (and other signal paths) via an ex-
ternal MIDI sequencer or the
DATA
port.
We’ll discuss all this in excruciating detail
later on
.
