Graphic equalizer
This is a 7-band graphic equalizer that allows you
to adjust the frequency response of the MONI-
TOR bus signal, providing a maximum of ±12 dB
of cut/boost for each frequency band.
You can use these sliders to reduce the level of fre-
quency bands at which feedback easily occurs. Fre-
quency response is flat when a slider is in the center
position. Moving a slider in the positive direction
will boost, and in the negative direction will cut.
This graphic equalizer affects both the MONI-
TOR bus signal that is output to the speakers and
the line level signal which is output from the
MONITOR jack (input/output panel 6).
E
EFFECT RTN control
This controls the level of the effect sound which
is returned from the built-in digital effect to the
MONITOR bus.
F
2TR IN control
This controls the level of the signal routed from
the 2TR IN jack (input/output panel 5) to the
MONITOR bus.
G
MASTER control
This adjusts the final level of the MONITOR bus.
It affects both the MONITOR bus signal which is
output to the speakers and the line level signal
which is output to the MONITOR jack (input/
output panel 6).
H
Peak level indicator
This indicator allows you to monitor the level of
the signal which is output from the MONITOR
jack (input/output panel 6).
Note: To avoid distortion, adjust the MASTER
control (G) so that the 0 indicator lights occa-
sionally.

LIMITER indicator
This indicator lights up when the level of the sig-
nal output from the power amp section reaches
the maximum and the limiter is activated. Adjust
appropriate control so that the indicator lights up
for only a short while when the signal reaches the
maximum level.
Note: The indicator lights up or flashes for a
longer duration if the power amp section is sig-
nificantly overloaded, which could result in
malfunction. Avoid such a situation.
J
Power amp select switch
Select one of the following three settings to route
the signals to the appropriate jacks, depending on
the speaker connection at the SPEAKERS jacks
(rear panel 1).
• MAIN-MON
With this setting, the MAIN bus signal will be
output from the SPEAKERS A 1/2 jacks and the
MONITOR bus signal is output from the
SPEAKERS B 1/2 jacks. The MASTER controls
(B, G) in the MAIN and MONITOR sections
are both effective.
• MAIN-MAIN
With this setting, the MAIN bus signal will be
output from the SPEAKERS A 1/2 jacks and
from the SPEAKERS B 1/2 jacks. Only the MAS-
TER control B in the MAIN section becomes
effective.
• MAIN BRIDGE
With this setting, the MAIN bus signal will be
output from the BRIDGE jack. The two power
amp channels will be bridge connected. Only the
MASTER control B in the MAIN section
becomes effective.
