ST OUT output select switch

This switch selects the signal which is output via the

ST

fader from the ST OUTPUT jacks.

ST position ( )

The ST OUTPUT jacks will output the ST bus signal

(the post-fader signals of groups 1~4, the input signals

from the RTN jacks, the return signal from the internal

digital effect, and the input signal from the TAPE IN

jacks).

GROUP position ( )

The ST OUTPUT jacks will output the pre-fader sig-

nals of groups 3/4.

When this position is selected, the input channel sig-

nals will be sent directly to the ST bus without passing

through the group buses 1~4. This setting lets you use

the MX12/4 as a simple 12 in-2 out mixer.

2

ST master fader

This fader adjusts the final combined level of all chan-

nels, and sends the signal to the ST OUTPUT jacks.

The meters allow you to view the L and R output levels.

3

GROUP 1~4 faders

These faders adjust the signal levels of groups 1~4, and

send their signals to GROUP OUTPUT 1~4 jacks

respectively and to the ST bus.

Groups 1 and 3 are sent to ST L, and groups 2 and 4 are

sent to ST R.

4

Stereo graphic EQ

This is a stereo 7-band graphic equalizer that adjust the

tonal quality of the signal output to the ST OUTPUT

jacks.

A

±

12dB boost or cut is provided at each of the fre-

quency bands 125, 250, 500, 1k, 2k, 4k, and 8kHz.

5

TAPE IN jacks

These are line level input jacks to which an external DAT recorder or CD player etc. can be

connected for monitoring. The signals which are input here are sent to the ST bus. The input

levels are adjusted by the TAPE IN ST control (

9

). Depending on the setting of the C-R•

PHONES select switch (

D

), the signal can also be monitored directly from the C-R OUT jack.

6

REC OUT jacks

These jacks allow an external DAT recorder or cassette recorder to be connected, to record the

same signal as the ST OUTPUT jacks.

The signals that are output from these jacks are not affected by the settings of the ST master

fader or the graphic EQ. Make recording level adjustments on the recording device.

7

PHANTOM indicator

This indicator will light when the PHANTOM switch (rear panel

2

) is on.

8

POWER indicator

This indicator will light when the MX12/4’s power is on.

The INS I/O jacks provide bi-directional connections using TRS (tip, ring, sleeve) phone

jacks. These connections require a special insertion cable such as shown in the following dia-

gram.

Note:

It is not possible to connect both the MIC INPUT jack and the LINE INPUT jack for

an individual input channel. Only one or the other jack may be used.

2 RTN L (MONO), R

These are unbalanced phone type line input jacks, with a nominal input level and impedance

of +4dB/600Ω.

The signals which are input from these jacks are sent to the ST bus and the MONI bus.

Normally, these jacks are used to receive the return signal from an external effect device such

as reverb or delay, but they can also be used as auxiliary stereo inputs. If only the L (MONO)

jack is connected, the same signal will be sent both to the R jack and L jack, for monaural

input.

3 SEND MONI 1, EFFECT/MONI 2

These are unbalanced phone type output jacks. The nominal input level and impedance are

+4dB/600Ω.

The MONI 1 jack outputs the MONI bus signal, and the EFFECT/MONI 2 jack outputs the

signal of the EFFECT bus or MONI bus. These are used to send signals to an external effect

unit or to a monitor system such as a cue box.

4 INPUT 9~12

These are unbalanced phone type stereo line input jacks, compatible with 600Ω line level

devices.

If only the L (MONO) jack is connected, the same signal will be sent both to the L and R jacks,

for monaural input. In this case, the group select switch (channel control section 6) will send

the same signal to the group buses 1/2 or 3/4.

5 ST OUTPUT (L, R)

These are balanced XLR type output jacks with a nominal output/impedance of +4dB/600Ω.

They provide stereo output of the mixed signal, and are normally connected to a power amp

etc. which drives the main speakers.

These outputs can also be used in order to record the signal at a level adjusted by the ST fader.

6 GROUP OUTPUT 1~4

These are unbalanced phone type output jacks which output the signals of group buses 1~4,

with a nominal output/impedance of +4dB/600Ω. Normally these are connected to the input

jacks of an MTR or an external mixer.

7 C-R OUT

This is a stereo phone type output jack for connection to a monitor system etc., with a nomi-

nal output/impedance of +4dB/10kΩ.

The source monitored by this jack is selected by the C-R•PHONES output select switch (mas-

ter control section C).

8 PHONES

This is a stereo phone type output jack for connecting a set of headphones.

The source monitored by the headphones is selected by the C-R•PHONES output select

switch (master control section C).

Note: An insertion cable can also be used when connecting this jack to a stereo monitor sys-

tem.

1 POWER switch

When this is on, power is applied to the unit.

When turning off the power, the rule for audio equipment is to turn off devices in the order of

their closeness to the speakers (normally beginning with the power amp).

2 PHANTOM switch

This switch turns the phantom power on/off for all channels 1~8.

Use this when you are using condenser microphones.

When this switch is on, +48V DC will be supplied to pins 2 and 3 of all XLR type MIC INPUT

connectors.

If you do not require phantom power, be sure to set this in the OFF position.
