Owner’s Manual
31. High EQ
The high EQ provides up to
15 dB of boost or cut above
12 kHz, and it is also flat (no
boost or cut) at the detent.
Use it to add sizzle to cymbals,
an overall sense of
transparency, or an edge to
keyboards, vocals, guitar and bacon frying. Turn it down
a little to reduce sibilance or to mask tape hiss.
32. Mid EQ And 33. Freq (Mono Channels Only)
The mono channels employ
a semi-parametric mid-sweep
EQ. The gain (up to 15 dB of
boost or cut) is set via the mid
eq [32], and then “aimed” at a
specific frequency, from
100 Hz to 8 kHz, via freq [33].
34. Low EQ
The low EQ provides up to
15 dB of boost or cut below
80 Hz. The circuit is flat at
the center detent position.
This frequency represents the
punch in bass drums, bass
guitar, fat synth patches, and
some really serious male singers who eat raw beef for
breakfast.
35. High Mid EQ Level (Stereo Channels Only)
The high mid EQ provides
up to 15 dB of boost or cut
at 2.5 kHz, and it is flat at
the detent. Midrange EQ is
often thought of as the most
dynamic because the
frequencies that define any
particular sound are almost always found within this
range. For example, the female vocal range as well
as the fundamentals and harmonics of many
higher-timbred instruments.
36. Low Mid EQ Level (Stereo Channels Only)
The low mid EQ provides up
to 15 dB of boost or cut at
400 Hz, and is flat at the
detent. Frequencies affected
typically include the male
vocal range as well as the
fundamentals and harmonics
of many lower-timbred instruments.

37. Pan
This control allows you to adjust
how much of the channel signal
is sent to the left versus the right
outputs.
With the knob panned hard left,
the signal feeds the main left,
group 1, or group 3 busses,
depending on the setting of the
assign switches [42]. With the knob
panned hard right, the signal feeds
the main right, group 2, or group 4
busses, again dependent on the
setting of the assign switches [42].
The balance control employs a
design called “Constant Loudness.”
If you have a channel panned hard
left (or right) and then pan to the
center, the signal is attenuated
about 3 dB to maintain the same
apparent loudness. Otherwise, it
would make the sound appear much
louder when panned center. This
control is properly called “BAL” for
balance in the stereo channels.
38. Mute
Mute switches do just what they
sound like they do. They turn off the
signal by “routing” it into oblivion.
Engaging a channel's mute switch
(almost) provides the same results
as turning the fader all the way
down (a pre-aux send is not affected
by the channel fader, but it is by
the mute switch). Any channel
assignments to main mix, group 1-2,
or group 3-4 will be interrupted and
all of the aux sends will be silenced
(both pre- and post-fader). The
channel insert [3] will continue to
provide a signal when a channel
is muted. The OL LED [39] will
illuminate when a channel's mute
switch is engaged.
39. OL LED
This LED indicates the channel’s
signal level after the gain and EQ
controls, but just before the
channel’s level. So even if the level
is turned down, you can see if the
channel is being overloaded.
