FCL (Feedback Channel Locating) lamp
(Channels 1 to 9/10)
This lamp is used during setup to identify any channel
that might be howling. Check these lamps when setting
up for a performance. If the lamp lights up, adjust the
channel’s equalizer 9 or channel fader H to reduce
the level so that the lamp goes off.
Input of a continuous sound (as from a CD player or
vocal) may cause the lamp to come on even in the
absence of howling.
9
Equalizer (HIGH, MID, and LOW)
This three-band equalizer adjusts the channel’s high,
mid, and low frequency bands. Setting the knob to the
“ ” position produces a flat frequency response for the
corresponding frequency band. Turning the knob to the
right boosts the corresponding frequency band, while
turning to the left attenuates the band.
On channels 1 to 6, the MID range is controlled by two
knobs. The upper knob sets the center frequency for
the mid range, while the lower knob sets the attenua-
tion (counterclockwise) or boost (clockwise) for the
range. (Again, setting the lower knob to “ ” produces
a flat response.) On stereo channel pairs 7/8 to 13/14
the mid-range frequency is fixed at 2.5kHz, so only
one MID knob is provided.
The following table shows the equalization type, the
base frequency, and the maximum cut/boost for each
of the three bands.

AUX Controls
• AUX1 (PRE)
This knob adjusts the channel’s signal level into the
AUX1 bus. The knob should generally be set close to
the “ ” position. On stereo channels, the L (odd) and
R (even) input signals are mixed before moving into
the AUX bus.
The channel faders do not operate on signals sent to
the AUX1 bus.
• AUX2 (PRE/POST)
This knob adjusts the channel’s signal level into the
AUX2 bus. The knob should generally be set close to
the “ ” position. Note that you can use the PRE
switch A to choose whether to feed the pre-fader or
post-fader signal into the AUX2 bus. On stereo chan-
nels, the L (odd) and R (even) input signals are mixed
before moving into the AUX2 bus.
If the PRE switch is on, the channel’s fader will not
have any effect on the signal into the AUX2 bus.
A
PRE Switch
Selects whether the pre-fader or the post-fader signal is
fed to the AUX2 bus. If the switch is on, the mixer
feeds the pre-fader signal to the bus. If off, the mixer
feeds the post-fader signal.
B
EFFECT Knob
Adjusts the level of the signal sent from the channel to
the EFFECT bus. If input is from a stereo channel pair
(7/8, 9/10, 11/12, or 13/14), the signals from the L and
R channels are mixed before moving into the bus. The
EFFECT bus signal is fed both to the internal digital
effector and to the SEND EFF jack I.
The level into the EFFECT bus is affected by the set-
ting of the channel’s fader
H
.
C
PAN Control (Channels 1 to 6); BAL Con-
trol (Channels 7/8 to 13/14)
The PAN control determines the positioning of the
channel’s signal on the Stereo L and R buses.
The BAL control sets the balance between left and
right channels. Signals into the L input (odd channel)
feed to the Stereo L bus; signals into the R input (even
channel) feed to the Stereo R bus.
If you are inputting to a stereo channel through the L
(MONO) jack only, the BAL knob operates as a PAN
knob.
D
ON Switch
Switches the channel on or off. (The indicator lights up
if the channel is on.) Be sure to turn on all the channels
that you wish to use. If you switch the channel off, you
cut off all of its signal feed into the Stereo, AUX, and
EFFECT buses.
To reduce noise, turn off all unused channels.
E
PEAK Indicator
Detects the peak level of the post-equalizer signal, and
lights up red when the level reaches 3 dB below the
clipping level.
F
SIGNAL Indicator
Lights up when a signal is being input into the channel.
G
PFL (Pre-Fader Listen) Switch
Set this switch on to feed the channel’s pre-fader signal
into the PFL bus, so that it can be monitored at the
PHONES jack. To set the switch on, press it in so that
it lights up.
• PFL switching and output are not affected by the
ON switch. You can monitor the channel’s
pre-fader signal through the PHONES jack even
when the ON switch is set off.
• The PFL (
G
,
N
,
d
) and AFL
e
switches select
the mix to be monitored at the PHONES jack. If
the channel’s PFL or AFL switch is ON, the chan-
nel’s output is mixed into the monitor signal to the
PHONES jack. If both switches are OFF, the chan-
nel output is not fed to the PHONES jack.
H
Channel Fader
Adjusts the signal’s output level. Use these faders to
adjust the volume balance among the various channels.
To reduce noise, set the fader sliders for unused chan-
nels all the way down.
