Operation procedures
After turning the power on, adjust the levels of the
input signals.
Adjusting line input channels (1–5)
1. Set the channel 1–5 GAIN knobs (
j
) to their cen-
ter positions.
2. Press the channel 1–5 SOURCE SELECT switches
(
0
), so that the SOURCE SELECT indicator ( A / B )
lights.
3. Press the channel 1–5 OUTPUT SEL switches (
o
)
to select the output channel stereo buses (1–3)
that receive the input signals of each channel.
4. When connecting an audio device to channel 1–2
LINE A / B (
b
) input jacks, set the LINE/PHONE
switch (
l
) to LINE .
5. Set the OUTPUT VOL (
q
) knob levels low.
6. Start playback on the connected audio device.
Use the
GAIN knobs (
j
) to adjust the levels so
that the channel 1–5 PEAK indicators (
9
) do not
light red.
7. Follow the above procedures to adjust other line
input channels with connected audio devices.
Adjusting the inputs of mics connected
to the MAIN MIC 1–2 INPUT jacks
1. Connect a mic to a MIC 1–2 INPUT jack (
1
), and
press the MIC 1–2 switch (
7
) so that the MIC 1–2
indicator (
7
) lights.
2. Press OUTPUT SELECT switches (
2
) to select
outputs for signals input through the MIC 1–2
INPUT jacks (
1
).
3. While checking the MIC 1–2 INPUT ( 5 ) and
PEAK ( 4 ) indicators, use the MIC 1–2 INPUT
VOLUME knobs (
3
) to adjust the mic input lev-
els.
4. Use the MIC 1–2 INPUT EQ knobs (
6
) to adjust
the 3-band (HIGH/MID/LOW) equalizers.
Output channels
Output signals can be sent to the following jacks from
the stereo output bus after the output equalizer.
0
MAIN OUTPUTS 1–3 (UNBALANCED) (
v
) and
MAIN OUTPUTS 1–3 (BALANCED) (
c
) jacks
0
MONITOR OUT jacks (
x
)
NOTE
The output level from the MONITOR OUT (
x
)
jacks cannot be adjusted.
Adjusting the levels output from the MAIN
OUTPUTS 1–3 (UNBALANCED) and MAIN
OUTPUTS 1–3 (BALANCED) jacks
While checking the output level indicators (
w
), use
the channel faders (
8
) and OUTPUT VOL (
q
) knobs
to adjust the output levels. The optimal output level
adjustment is usually when the output level indica-
tors (
w
) light around 0 dB.
When an amplifier is connected to the MAIN OUT-
PUTS 1–3 (UNBALANCED) (
v
) or MAIN OUTPUTS
1–3 (BALANCED) (
c
) jacks, set the ATTENUATOR (
h
)
switch to OFF if it accepts high gain or ON (-6dB) if it
accepts low gain.
Use the
OUTPUT EQ knobs ( e ) to adjust the 3-band
(HIGH/MID/LOW) equalizers for the output sound.
Using the talkover function
When the talkover function is turned on by pressing
the TALKOVER ON switch (
i
), the levels of channels
1 will be automatically lowered when sound is input
from a mic connected to a MIC 1–2 INPUT (
1
) jack,
making the mic signal easier to hear.
To turn the talkover function off, press the
TALKOVER
ON (
i
) switch to disable it ( TALKOVER ON (
i
) indi-
cator becomes unlit).
Use the
TALKOVER DAMP (
y
) and TALKOVER TIME
(
u
) knobs to adjust the attenuation level and re-
sponse time.
Listening to channel pre-fader signals
By pressing the PFL (
p
) switches of channels to turn
them on, you can enable headphone monitoring of
individual channels 1–5, even when their faders (
8
)
are set at minimum values.
1. Press PFL (
p
) switches so that their PFL indica-
tors light, and turn the MIXING (
d
) knob to PFL .
To monitor the signal before it is sent to the
stereo output bus, turn the MIXING (
d
) knob to
MONITOR .
2. Use the PHONES VOLUME (
a
) knob to adjust
the monitoring output level.
