U
LEVEL controls
These knobs enable you to adjust the level of the
signals input from the mixer section to the power
amp section. Rotating the knob clockwise will
raise the level of the input signal. Use a screw-
driver of a width of 3mm or less to adjust the
knob.
If an external piece of equipment is connected to
the P.AMP IN jacks (input/output panel 6),
these knobs adjust the input sensitivity of the
power amp (the input level that will provide the
maximum output level in the power amp sec-
tion). The sensitivity range is +18 dB~+4 dB, and
rotating the knobs clockwise raises the input sen-
sitivity.
Note: If the Power amp select switch V is set
to MONO (BRIDGE), only the L/BRIDGE
LEVEL control becomes effective.

Select one of the following three settings to spec-
ify the signals to be routed to the corresponding
jacks according to the speaker connection at the
SPEAKER jacks 1 on the rear panel.
• ST1 L-ST1 R
The STEREO bus signals are output from the
SPEAKERS L/MONI1 1/2 jacks and the SPEAK-
ERS R/MONO 1/2 jacks. The final level of these
signals is adjusted by the master ST 1 fader.
• MONI 1-MONO
The MONITOR 1 bus signals are output from the
SPEAKERS L/MONI1 1/2 jacks, and a monaural
signal that is a mix of the STEREO bus signals is
output from the SPEAKERS R/MONO 1/2 jacks.
The final level of these signals is adjusted by the
master MONI 1 fader and the MONO fader.
• MONO (BRIDGE)
The monaural signal that is a mix of the STEREO
bus is output from the BRIDGE jack. The final
level of this signal is adjusted by the master
MONO fader. Set the switch to this position
when you connect only one speaker to play a loud
sound.
