Section 3
Mid Frequency Equalizer
This control provides 12dB of boost or cut at the frequency selected by the
Mid Select control. This is
a
peak/dip type equalizer. It affects sounds both above
and below the selected frequency within
a
range of approximately one octave
(Q-l
This means that boosting the mid equalizer at 2k affects not only 2k but
also the frequencies surrounding it, but to
a
lesser degree. This control has no
effect on the signal when set to the centre flat position.
Low Frequency Equalizer
This control boosts or cuts the low frequency content of the signal source, by
up to
below 60 Hz or 120 Hz depending on the position of the low frequency
select switch. It has a shelving characteristic and at its centre position the control
has no effect on the low frequency content.
Low Frequency Select Switch
This switch is used to select the frequencies affected by the Low Frequency
Equalizer. In the up position, a corner frequency of
is selected; when
engaged,
is selected.
Eq In Switch
This switch is used to activate the EQ section in the channel signal path.
When the switch is in the up position, the channel signal bypasses the EQ section.
Hi Pass Filter Switch
Depressing this switch engages an
filter. This filter is
independent of the
channel EQ and is useful for eliminating stage rumble,
wind noise and other low frequency sounds.
Pan Control
The input signal can be placed anywhere in the stereo image by turning the
PAN to the right or the left. When the pan control is turned fully left, the input signal
is routed to the left stereo output only. Turned fully right, the signal is routed to the
right stereo output. When the PAN is in the centre position, the signal is equal in
level to both the left and the right.
Mute
Switch
When depressed, this switch mutes or cancels the signal from the channel
after the channel fader. It also mutes signals going to any Aux mixes. An option
allows the Pre-EQ Aux source to be unaffected by the MUTE switch (See USER
CONFIGURED OPTIONS section.)
