Setting phantom power
Phantom power can be turned on when an mic that requires it is
connected to a MIC/LINE INPUT (BALANCED) 1/2 jack.
1. On the
INPUT 1-2
screen, select the
PHANTOM
item. (See
“Opening the INPUT 1-2 and INPUT 3-4 screens” on page
19.)
2. Turn phantom power on or off.
Options:
OFF
(default),
ON
3. When finished, press the STOP/HOME [8] button to return
to the Home Screen.
Phantom power (48V) is turned on and supplied to the mics
connected to the MIC/LINE INPUT (BALANCED) 1/2 jacks.
CAUTION
Before making connections, turn this unit and all equipment
to be connected off (or put into standby).
Confirm that phantom power is OFF before connecting
a line level device to a MIC/LINE INPUT (BALANCED)
1/2 jack. If you connect a line level device while phantom
power is being supplied, that device and this unit could be
damaged.
Do not connect or disconnect mics with the MIC/LINE
INPUT (BALANCED) 1/2 jacks when the phantom power
is set to ON. Doing so could cause a loud noise and might
damage the equipment.
Turn phantom power ON only when using a condenser
microphone that requires phantom power. Turning
phantom power on when a dynamic mic or other mic that
does not require it is connected could damage this unit and
connected equipment.
When using condenser mics that require phantom power
and dynamic mics together, be sure to use balanced
dynamic mics. Unbalanced dynamic mics cannot be used
when phantom power is enabled.
Supplying phantom power to some ribbon mics will break
them. If you are unsure, do not supply phantom power to a
ribbon mic.
Some condenser microphones will not operate when
phantom power is set to 48V.
Using the Level Control Function
You can set the input level control function.
1. On the
INPUT 1-2

LVL CTRL
item.

19.)
2. Set the level control function used.

LIMITER
This prevents distortion of sound due to
sudden excessive input.
AUTO LEVEL

or too high, the input level will be
increased or decreased automatically to
an appropriate level.
3. When finished, press the STOP/HOME [8] button to return
to the Home Screen.
An icon for the set level control function will appear on the
Home Screen.
CAUTION
Distortion of sounds may occur when signals that are very
loud are input even if the
LIMITER
function is activated. In
such a case, lower the input level or manually.
NOTE
The input level cannot be changed if the level control
function is set to
AUTO LEVEL
. (See “Adjusting the input
level” on page 20.)
