Using condenser microphones (Phantom Power)
Most condenser microphones need a supply of power known
as phantom power in order to operate.
Accordingly, the BR-1600CD can supply phantom power at
+48 V to condenser microphones connected to any of the
XLR-type connectors for INPUT 1 through INPUT 8.

1.
Before proceeding, turn INPUT SENS knobs 1 through
8 fully counter-clockwise in order to reduce the input
volumes, and then move the MASTER fader and
INPUT LEVEL knobs all the way down.
If any of these volumes is not reduced, a loud click may
be output when the phantom power is turned on or off.
2.
Press [UTILITY].
The Utility screen will appear.
fig.12-12d
3.
Move the cursor to the SYSTEM icon and press
[ENTER/YES].
Alternatively, you can press [F1] (SYSTEM) if the
SYSTEM icon is currently displayed.
The System Parameter screen will appear.

4.
Move the cursor to “Phantom” and select “ON” using
the TIME/VALUE dial.
fig.53-20d
ON:
Phantom power will be supplied.
OFF:
Phantom power will not be supplied.
Note that when turned on, phantom power will be
supplied to all XLR connectors for INPUT 1 through
INPUT 8.
Phantom power
Condenser microphones generally contain a pair of
thin opposing electrodes. When a voltage is applied
across these electrodes, any vibration resulting from
incoming audio will be output as electrical waves.
However, since these waves are very weak, they
must be boosted using amplification circuitry within
the microphone itself. Phantom power is used to
drive this amplification circuitry.
Certain types of condenser microphone use internal
batteries as a source of power; accordingly, there
will be no need to supply phantom power in such a
case.
• Phantom power should always be turned off when
audio sources other than condenser microphones are
being connected to the BR-1600CD’s. In fact,
dynamic microphones, audio players, and the like
can be damaged by this power supply. Always refer
to the user’s manual for the microphone to be used
in order to confirm its phantom-power
specifications.
• The BR-1600CD’s MASTER fader, INPUT SENS 1
through 8 knobs, and INPUT LEVEL knobs must be
moved all the way down when phantom power is
being turned on or off. If this precaution is not
observed, there is a possibility that amplifiers,
speakers, and the like may be damaged by loud
noises generated upon switching.
