+48V Switch/Indicator

This switch toggles phantom power on and off for a
monaural channel. When the switch is turned on, the
+48V indicator will light, and DC +48V phantom power
will be supplied to Pin 2 and 3 of the corresponding
XLR-type INPUT A jacks. Turn this switch on when using
a phantom-powered condenser microphone.

• Be sure to leave this switch off if you do not need
phantom power.

•When turning phantom power on, be sure that only a
condenser microphone is connected to the INPUT A
jack of the monaural channel. Other devices may be
damaged if connected to phantom power. This precau­tion does not apply to balanced dynamic microphones,
however, as these will not be affected by phantom
power.

•To avoid damage to speakers, be sure to turn off
amplifiers (or powered speakers) before turning this
switch on or off. It’s also a good idea to turn the mixer’s
output controls - STEREO OUT master fader and
GROUP OUT faders - all the way down. If you omit this
precaution, you may damage your hearing or your
equipment.

COMP Control/Indicator

0

Adjusts the amount of compression applied to the chan­nel. As the COMP knob is turned to the right the com­pression ratio increases while the output gain is
automatically adjusted accordingly. The result is
smoother, more even dynamics because louder signals
are attenuated while the overall level is boosted. The
COMP indicator will light when the compressor oper­ates.

NOTE

·Avoid setting the compression too high, as the higher
average output level that results may lead to feedback.

A EQ (Equalizer): HIGH, HI-MID, LO-MID, LOW

This is a four-band equalizer, providing adjustments for
four frequency bands (HIGH, HI-MID, LO-MID, LOW).
Setting the gain control to the “▼” position produces a
flat response in the corresponding band. Turning the
gain control to the right boosts the corresponding fre­quency band, while turning to the left attenuates the
band. The HI-MID and LO-MID bands of monaural
channels provide a frequency control that lets you
adjust the center frequency.
The following table shows the EQ type, frequency, and
maximum cut/boost for each of the bands.

Monaural channel

C AUX Controls (1–8)

These adjust the level of the signals sent from the input
channel to AUX buses 1–8. These knobs should gener­ally be set close to the “▼” (nominal) position. The sig­nal adjusted by these controls is determined by the PRE
switch (D).

D PRE Switches

For each two buses, these switches select whether the
signal sent to the AUX buses will be taken after the
equalizer and before the channel fader (pre-fader), or
after the channel fader (post-fader). If this switch is ON,
the pre-fader signal is sent to the AUX bus, and will not
be affected by the channel fader.

NOTE

· If necessary, the pre-fader signal sent to the AUX buses
can be changed to the signal before the equalizer by
changing an internal jumper. A fee will be charged for
this modification. In this case, the signal will be sent to
the AUX buses even if the input channel’s ON switch is
turned off. For details, contact to your Yamaha dealer
listed at the end of this manual.

E PAN Control

This control determines the stereo positioning of the
monaural channel signal on the buses.
Rotate the knob clockwise to pan the signal to the odd
channels of the GROUP buses and the ST L bus, and
counter-clockwise to pan the signal to the even chan­nels of the GROUP buses and the ST R bus.

F BAL Control

Adjusts the left and right volume balance of stereo
channels. The signal input to the INPUT L jack will be
sent to the odd channels of the GROUP buses or to the
ST L bus, and the signal input to the INPUT R jack will
be sent to the even channels of the GROUP buses or to
the ST R bus.

G ON Switch/Indicator

When this switch is on, that channel will be enabled and
the indicator will light.

NOTE

· Even if the ON switch is off, you can turn on the PFL

switch (K) and monitor the signal before the channel
fader via the MONITOR OUT jacks and the PHONES
jack.

H Input Meter

Three LEDs indicate the input channel signal level after
the equalizer. The “-20” LED will light if the input signal
level reaches -20 dB, and the “0” LED will light at nomi­nal level. The PEAK LED will light red when the input sig­nal reaches 3 dB before clipping.

I Bus Assign Switches

These switches determine the bus(es) to which each
channel’s signal is sent. Turning a switch on will output
the signal to the corresponding bus.

• 1-2, 3-4, 5-6, 7-8 switches: Assign the channel’s
signal to the GROUP 1/2–7/8 buses.

• ST switch: Assigns the channel’s signal to the Stereo
L and R buses.

• MONO switch: Assigns the channel’s signal to the
MONO bus.

NOTE

· If you want the signal to be output to the corresponding
bus(es), turn on the channel ON switch (G).

J MUTE Switches (1–4)

These assign the channel’s mute on/off to switches 1–4.
If you turn on the MUTE master switches (1–4)
(page 15) located in the MUTE MASTER section, the
input channels whose corresponding MUTE switch is on
will be muted.

NOTE

·When a channel is muted, the ON indicator (G) will go
dark.

· Even if a channel is muted, you can turn on the PFL
switch (K) and monitor the signal before the channel
fader via the MONITOR OUT jacks and the PHONES
jack.

Owner’s Manual

K PFL Switch/Indicator

When the PFL switch is on, the indicator will light and
the channel pre-fader signal is output to the PHONES
and MONITOR OUT jacks for monitoring.

NOTE

·When you turn on the PFL switch, the PFL indicator of the
MONITOR section (page 18) will light.

L Channel Fader

Adjusts the output level of the input channel signal. Use
these faders to adjust the balance between the various
channels.

NOTE

·To minimize noise, the faders of unused channels should
be set to the lowest position.

· The channel faders will affect the ST, MONO, GROUP 1–
8, and AUX 1–8 (when the PRE switch is off) buses.

AUX RETURN Jacks

1

These are unbalanced phone-jack type line inputs. Sig­nals input from these jacks can be sent to the GROUP 1/
2–7/8, ST L/R, MONO, and AUX 1–4 buses. To the
MONO and AUX 1–4 buses, a mix of the L/MONO and R
signal is sent. These jacks are typically used to receive
the signal returned from an external effect device
(reverb, delay, etc.).

NOTE

· These jacks can also be used as auxiliary stereo inputs.

· If you connect to the L/MONO jack only, the mixer will
recognize the signal as monaural and will send the identi­cal signal to both the L/MONO and R jacks.

2 AUX Controls (1–4)

These adjust the level at which the signals from the AUX
RETURN jacks are sent (with L and R mixed) to the AUX
1–4 buses.
The “▼” position of the knob is nominal level (0 dB).

3 Bus Assign Switches

These switches determine the bus(es) to which the sig­nal is received from the AUX RETURN jacks.

• 1-2, 3-4, 5-6, 7-8 switches: Send the signal to the
GROUP 1/2–7/8 buses.

• ST switch: Sends the signal to the ST L/R bus.

• MONO switch: Sends the signal to the MONO bus.

4 RETURN Control

Adjusts the level of the signal sent from the AUX
RETURN jacks to the GROUP 1/2–7/8, ST L/R, or MONO
buses.
The “▼” position of the knob is nominal level (0 dB).

NOTE

· The signals sent to AUX 1–4 are not affected by the
RETURN control.

5 PFL Switch/Indicator

When the PFL switch is on, the indicator will light and
