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

Press the SELECTED CHANNEL section
[HOME] key.
The SELECTED CH VIEW screen will appear in the
display.
1 HA popup button
B GAIN knob
2
Use the LAYER section to select the desired
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.
5
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.

meter located immediately to the right of the GAIN
knob in the screen.

To turn on phantom power, move the cursor
to the +48V button of the desired channel in
the window, and press the [ENTER] key.

can also access the above popup window by pressing the
SELECTED CHANNEL section [HA GAIN] encoder.
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.
