5.2 Effects

The Compact Mobile 2 has a built-in (internal)
digital effects processor, with the select-switch you
can choose between 4 different effects:
1 = reverb 1 (short)
2 = reverb 2 (long)
3 = delay (320 ms)
4 = chorus
The efx-level-control determines the intensity of
the internal effects (left stop = no effect).
Furthermore an additional effects unit
(external effect) may be connected to the
Compact Mobile 2. For this purpose use the send
and return sockets on the rear side of the amplifier
(send goes to input, return to the output of the
external effects device). The intensity of the effect
is adjusted at the external effects unit.
With the efx-pan control the different effects are
blended with the original signal. The efx-pan works
as follows:
left stop: internal effect on channel 1
external effect on channel 2
mid position: internal effects on channel 1 + 2
external effects on channel 1 + 2
right stop: internal effects on channel 2
external effects on channel 1

5.3 Footswitch

A standard double-footswitch (on-/off-switch)
can be plugged into the footswitch-socket on the
rear side of the amplifier via stereo cable. By this
footswitch the internal and external effects can be
switched on and off.
5.4 Phantom power
Microphones requiring 48 V phantom power
can be connected to the XLR-socket of channel
2 directly. Factory-provided phantom power is
activated but, if required, may be deactivated by an
internal jumper.
In contrary 9 V phantom power, if required, can
additionally be activated in channel 1 by an internal
jumper.
Please note: For both alterations the device must
be opened, therefore only qualified service per-
sonnel may carry out the modifications concer-
ning the de-/activating of phantom power.

General Note: Use of 48 V or 24 V phantom power
(Phantom power = remote supply, here: powering
an audio device via the connected audio line)
Turn on the phantom power only if the unit connec-
ted to an XLR socket that is designed to handle it!
In general, suitable units are e.g. condenser
microphones, active DI-boxes and other special
audio devices, whose power supply is drawn from
the phantom power. Such devices are also labelled
accordingly; please heed the permissible power
consumption (max.10mA).
High-quality dynamic microphones with a balanced
signal need no phantom power, but can handle it
anyway.
Other devices, which have not been designed
explicitly for phantom power operation, can suffer
from considerable malfunctions and damage may
result as well.
Examples of devices that may be damaged by
incorrect application of phantom power include:
Low-cost dynamic microphones with a mono jack-
plug (unbalanced signal) that were fitted afterwards
with an XLR connector.
Audio devices with a balanced XLR output (e.g.
DI-boxes, effects devices, instrument preamps with
a DI output etc.) which are not protected against
phantom power applied to their XLR output. (The
DI connectors on AER products are protected
against applied phantom power.)
Other audio devices (such as preamps, effects
pedals etc.) whose unbalanced line output was
replaced by an XLR socket.
If in doubt please consult the manufacturer of the
device you are using.
