P48 V Switch

This switch toggles phantom power on and off. If you set
the switch on, the mixer supplies power to all channels
that provide XLR mic input jacks (CHs 1, 2, 3/4, 5/6).
Set this switch on (

) when using one or more con-

denser microphones. 

When this switch is on, the mixer supplies DC
+48 V power to pins 2 and 3 of all XLR-type MIC
INPUT jacks.

Be sure to leave this switch off (

) if you do not

need phantom power.

When tuning the switch on (

), be sure that

only condenser mics are connected to the XLR
input jacks (CHs: 1 to 5/6). Devices other than
condenser mics may be damaged if connected to
the phantom power supply. Note, however, that
the switch may be left on without problem when
connecting to balanced dynamic microphones. 

To  avoid damage to speakers, be sure to turn off
amplifiers (or powered speakers) before turning
this switch on or off. We also recommend that you
turn all output controls (ST Master LEVEL Con-
trol, etc.) to minimum settings before operating
the switch, to avoid risk of loud noises that could
cause hearing loss or device damage.

2

RETURN Control

Adjusts the level of the signal sent from the RETURN
jacks (L (MONO) and R) to the Stereo bus.

If you supply a signal to the RETURN L (MONO)
jack only, the mixer outputs the identical signal to
both the L and R Stereo buses.

3

2TR IN Control

Adjusts the level of the signal sent from the 2TR IN jack
to the Stereo bus.

4

ST Master LEVEL Control

Adjusts the signal level to the ST OUT jacks.

5

C-R/PHONES LEVEL Control

Controls the level of the signal output to the PHONES
jack and the C-R L and R jacks.

6

Level Meter

This LED display shows the level of the signal fed to the
Stereo bus. The “0” point corresponds to the standard
output level. The indicator lights up red when the output
hits the clipping level.

7

POWER Indicator

This indicator lights up when the mixer’s power is ON.

8

DIGITAL EFFECT

• PROGRAM Dial

Selects the internal digital effect to be applied. You can
select from 16 effects, as shown in the table.
