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.
