5.6. Phantom-power
48 V phantom power at microphone input
Microphones that require 48 V phantom power
(P 48) can be connected directly by an XLR plug.
The 48 V phantom power is switched by the 9 V/48 V
switch in ch. 1/3.
For channels 2/4 the amplifi er is supplied with the
phantom power enabled, but it can be disabled by an
internal jumper. (see note)
Please also read the general notes on
phantom power.
Please note: For the alteration mentioned above, the
device must be opened, therefore only qualifi ed per-
sonnel may carry out the de-/activation of the phantom
power.
9 V phantom power at line input
The 9 V phantom power supplies instrument preamps
with power (instead of a battery) that are prepared ac-
cordingly. Such preamps are connected to input 1and 3
by a stereo jack cable.
The phantom power can be switched on by the 9 V/48
V switch. The amplifi er supplies either 9V or 48 V depen-
ding on the kind of plug being used.
Sources that don't need phantom power should always
be connected via a mono jack cable (not stereo) as a
precaution. This way the phantom power cannot get to
the source and possibly damage it.
Also make sure that the plugs are fully plugged in.
Notes on the use of phantom power
Phantom power means remote power supply of an
audio device (e.g. microphone) via the audio line.
Only suitable devices should be connected to an
input with (activated) phantom power.
Such devices are also marked accordingly. Please
heed the permissible power consumption (see
technical data).
Some devices do not need phantom power
but tolerate it.
Other devices that have not been designed expli-
citly for phantom power operation can suff er from
considerable malfunction and damage may result
as well.
In case of uncertainty please consult the
manufacturer of your accessories.
