TO ST Switch
If this switch is on (
), the mixer sends the signals pro-
cessed by the GROUP 1-2 fader (
2
) onto the Stereo bus.
The Group 1 signal goes to Stereo L and the Group 2 sig-
nal goes to Stereo R.
4
Master SEND
• Master AUX Control
Adjusts the signal level to the corresponding AUX
SEND jack.
• Master EFFECT Control
Adjusts the level of the signal on the EFFECT bus. This
is the signal that is output through the EFFECT jack.
These Master SEND controls do not affect the
level of the signal sent from the EFFECT bus to
the internal digital effector.
5
RETURN
• AUX Control
Adjust the level of the mixed L/R signal sent from the
RETURN jacks (L (MONO) and R) to the AUX bus.
• ST Control
Adjust 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.
6
2TR IN Control
Adjusts the level of the signal sent from the 2TR IN jack
to the Stereo bus.
7
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 1–4, 5/6, 7/8).
Set this switch on when using one or more condenser
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 7/8). 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 fader, GROUP
1-2 fader, etc.) to minimum settings before oper-
ating the switch, to avoid risk of loud noises that
could cause hearing loss or device damage.
