Controls and Functions

q Equalizer controls [HIGH]/[MID]/[LOW]

For adjusting the [HIGH], [MID], and [LOW] audio frequencies. Turn-

ing the control to the right amplifies (boosts) the corresponding fre-

quency band, while turning to the left attenuates (cuts) the band.

Setting the control to the “t” position produces a flat response in the

corresponding band.

w [AUX1] send controls (Channels 1 – 11/12)

[AUX2/FX] send controls (Channels 1 – 11/12)

For adjusting the levels of each signal sent to the AUX1 and AUX2/

FX (built-in effects) buses from each channel independently. On

channels 5/6 to 11/12, the Line L (odd) and Line R (even) input sig-

nals are mixed before being sent into the AUX1 and AUX2/FX buses.

Adjust the controls so that they are near the “t” (nominal) position.

e [LEVEL] controls (Channels 1 – 11/12)

Signal indicators (Channels 1 – 11/12)

For adjusting the volume for each channel. When each channel

receives an input signal, the signal indicator lights up. To reduce

noise, set all [LEVEL] controls on unused channels to the minimum.

r [COMP] controls

For adjusting the amount of compression applied to the correspond-

ing channel. As the [COMP] control is turned to the right, the thresh-

old, ratio, and output gain are adjusted simultaneously.

t [PHANTOM +48V] switch

Turn this switch on ( ) to supply all the XLR input jacks (channels

1 to 11/12) with DC +48 V phantom power. Turning on the switch

supplies power to condenser microphones or a DI (direct injection

box). When it is on, the switch lights up.

NOTE

The [AUX1] send control is a PRE setting that is not affected by the

[LEVEL] control, and the [AUX2/FX] send control is a POST setting that is

affected by the [LEVEL] control.

NOTE

Avoid raising the level of the [COMP] control too high, as the higher aver-

age output level that results may lead to feedback.

NOTICE

Follow the important precautions below, in order to prevent noise

and possible damage to external devices and the mixer when you

operate this switch.

• If you do not need phantom power, or when you connect a device

that does not support phantom power, be sure to leave this switch

off or connect via the phone (channels 1 to 7/8) / RCA-pin (9/10

and 11/12) / stereo mini (11/12) plugs.

• Do not connect or disconnect cables while this switch is on.

•Turn @3 AUX1, AUX2, and STEREO MASTER [LEVEL] controls to

the minimum setting before operating this switch.

y [ MIC/ LINE] switches (Channels 1 – 4)

For channels with low-level input signal devices such as micro-

phones, set the switches to the “ MIC” position. For channels with

high-level input signals such as electronic instruments and audio

devices, set the switch to the “ LINE” position.

u [HPF] (High Pass Filter) switches (Channels 1 – 3)

Turning this switch on ( ) applies a high-pass filter that attenuates

frequencies below 80 Hz in the signal by a slope of 12 dB/octave.

This function should be kept on when using vocals in order to reduce

noise from vibration or wind picked up by the microphone.

i [Hi-Z] switch (Channel 4)

Turn this switch on ( ) when you wish to connect instruments with

passive pickups such as acoustic-electric guitars or electric bass

guitars that do not have internal batteries. It enables such devices to

be directly connected to the mixer without the need for a DI (direct

injection box). This function affects only the phone jack input.

o [MIC/LINE] input jacks (Channels 1 – 4)

For connecting microphones, guitars, electronic musical instruments

or audio devices. These are compatible with both XLR and phone

plugs.

!0 [MIC] input jacks (Channels 5/6, 7/8, 9/10, 11/12)

These are balanced XLR microphone input jacks.

!1 [LINE] input jacks (Channels 5/6, 7/8, 9/10, 11/12)

For connecting line-level devices such as electronic instruments,

acoustic-electric guitars, CD players, and portable audio players.

These are compatible with TS phone, RCA-pin, and stereo mini

plugs. Using only the [L/MONO] jacks results in the stereo left and

right channels outputting the same signal.

• Channels 5/6, 7/8: TS phone

• Channel 9/10: RCA-pin

• Channel 11/12: RCA-pin, stereo mini

!2 FX RTN (Effect Return) [PARAMETER] control

For adjusting parameters (depth, speed, etc.) for the selected effect

program. The last value used with each effect program is saved.

NOTE

If desired, a single channel’s [LINE] and [MIC] jacks can be used together

at the same time. But note that the levels cannot be adjusted indepen-

dently. The stereo mini jack has priority for channel 11/12 [LINE] input jack.

NOTE

When you change to a different effect type, the mixer automatically

restores the value that was previously used with the newly selected effect

(regardless of the current position of the FX RTN [PARAMETER] control).

XLR Phone

RCA-pin Stereo mini

!3 FX RTN [AUX1] send control

For adjusting the level of the signal sent from the built-in effect unit to

the AUX1 bus.

!4 FX RTN [LEVEL] control

Signal indicator

For adjusting the level of the effect sent from the built-in effect unit to

the STEREO L/R bus. The signal indicator lights up when a signal is

received by the built-in effect unit.

!5 FX RTN [FX ON] switch

For turning the corresponding built-in effect on or off. It lights up

when it is switched on ( ).

NOTE

The FX RTN [LEVEL] control does not affect the level of the signal sent to

the AUX1 bus.

NOTE

If this switch is on and the foot switch (see “!6 FX RTN [FOOT SW] jack”)

is used to mute the built-in effect, the switch flashes.
