Setting phantom power
Phantom power can be turned on when an external mic that
requires it is connected to an IN 1/IN 2/IN 3/IN 4 jack.
1. On the
MIC POWER
page, select the
PHAN
item. (see
“Menu operation procedures” on page 12)
2. Select a channel that requires phantom power and turn
phantom power on/off.
Options:
OFF
(default),
ON
3. When finished, press the MENU button to return to the
Home Screen.
When stopped, if you set the
PHAN
item on the
MIC POWER
page to ON, a pop-up message appears confirming that you
want to turn phantom power on (as long as the
SEL
item on
the
INPUT
page for the selected channel is set to IN 1-2 or IN
3-4).
When the confirmation pop-up message opens, press the DATA
dial to turn phantom power on for the IN 1/IN 2/IN 3/IN 4 jack
and supply phantom power (
24V
or
48V
) to the connected
mic.
Use the
MIC POWER
page to set the voltage to
24V
or
48V
.
(see “Setting the phantom power voltage” on page 22)
NOTE
•
When the
GAIN
item is set to
LINE
or the
SEL
item is set
to EXT IN or INT on the
INPUT
page, phantom power will
not be output even if the
PHAN
item is set to ON, so the
pop-up message will not appear.
•
Battery power will be consumed faster when set to
48V
than when set to
24V
.
CAUTION
•
Confirm that phantom power is OFF before connecting a
line level device to an IN 1 , IN 2 , IN 3 or IN 4 connector.
If you connect a line level device while phantom power is
being supplied, that device and this unit could be damaged.
•
When using a condenser microphone, before connecting to
or disconnecting from an IN 1 , IN 2 , IN 3 or IN 4 connector,
confirm that the phantom power for that jack is OFF. If you
connect or disconnect a mic while phantom power is being
supplied, that mic and this unit could be damaged.
•
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.
•
When using USB bus power, the unit might not be able to
supply phantom power depending on the computer. In this
case, use a TASCAM PS-P515U AC adapter (sold separately).
•
Some condenser microphones will not operate when
phantom power is set to
24V
.
•
Do not connect or disconnect the AC adapter when using
phantom power. The unit could turn off even when batteries
are installed, resulting in recorded data becoming damaged
or lost.
Setting the phantom power voltage
Use the
VOLTAGE
item on the
MIC POWER
page to set the
supplied power voltage used when an external mic that requires
phantom power is connected.
1. On the
MIC POWER
page, select the
VOLTAGE
item. (see
“Menu operation procedures” on page 12)
2. Set the supplied phantom power voltage.
Options:
24V
,
48V
(default)
NOTE
Battery power will be consumed faster when set to
48V
than when set to
24V
.
3. When finished, press the MENU button to return to the
Home Screen.
