7 PHANTOM +48 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.
n 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 (
need phantom power.
• When tuning the switch on (
condenser mics are connected to the XLR input
jacks (CHs: 1 to 7/8). Devices other than con-
denser mics may be damaged if connected to the
phantom power supply. Note, however, that the
switch may be left on without problem when con-
necting 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 operat-
ing the switch, to avoid risk of loud noises that
could cause hearing loss or device damage.
8 2TR IN/USB Switch (TO ST/TO C-R)
Determines whether the stereo signal received via the
2TR IN connectors and USB interface is sent to the
stereo bus or the C-R OUT connectors and PHONES jack
(level meter). When the 2TR IN/USB switch is set to TO
C-R, the signal is sent to the C-R OUT connectors and
the PHONES jack.
9 ST/GROUP Switch
Determines whether the stereo bus or group bus signal is
sent to the C-R OUT connectors and PHONES jack (level
meter).
) C-R/PHONES Control
Controls the level of the signal output to the PHONES
jack and the C-R OUT L and R jacks.

! Level Meter

This LED meter displays the level of the signal selected
by the PFL, ST/GROUP, and 2TR IN/USB switches. The
"0" LED corresponds to nominal level. The PEAK LED will
flash red when the signal level approaches clipping level.

@ POWER Indicator

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

# PHONES Jack

Connector for headphones. This is a stereo phone-type
output jack. The PHONES jack outputs the same signal
that is output via the C-R OUT connectors.
n The signal monitored by these jacks is selected by the
settings of the ST-GROUP toggle switch, the 2TR
IN/USB switch, and the PFL switches on the input
channels.
