Here’s how to make HA (Head Amp) settings such as phantom power on/off, gain, and phase for
each input channel.

fader layer.
3
Press a [SEL] key in the channel module
section or ST IN section to select the input
channel that you want to operate.
4
If you only want to adjust the HA gain for
that channel, operate the SELECTED
CHANNEL section [HA GAIN] encoder.
You can obtain the same result by moving the cursor to
the GAIN knob in the SELECTED CH VIEW screen
and operating the dial or the [DEC]/[INC] keys.

If you want to edit detailed parameters such
as phantom power on/off and phase, move
the cursor to the HA popup button or GAIN
knob in the HA field of the SELECTED CH
VIEW screen, and press the [ENTER] key to
access the HA/PATCH popup window.
In the HA/PATCH popup window you can adjust the
HA gain, switch phantom power on/off, and switch the
phase for sets of eight channels. This popup window
shows the parameters for the eight channels that
include the channel you selected in step 3.

HINT
• If you don’t need phantom power, be sure to turn this but-
ton off.
• Before you turn phantom power on, make sure that no
devices other than phantom-powered devices, such as a
condenser microphone, are connected. Otherwise, you
risk damaging the devices.
• Do not connect or disconnect a device while phantom
power is applied. Doing so can damage the connected
device and/or the unit itself.
•To protect your speaker system, leave the power amps
(powered speakers) turned off when switching the phan-
tom power on/off. We also recommend that you set all
output level faders to the minimum position. Otherwise,
high-volume output may damage your hearing or equip-
ment.
CAUTION
• The PAD will be internally switched on or off when the HA
gain is adjusted between -14 dB and -13 dB. Keep in mind
that noise may be generated if there is a difference between
the Hot and Cold output impedance of the external device
connected to the INPUT connector when using phantom
power.
NOTE
• If you want to use phantom power, you must first turn ON the
+48V MASTER ON/OFF button located in the SYSTEM
SETUP screen.
