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
48V 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 jum-
per.
In contrary
9V phantom power
, if required, can ad-
ditionally 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 48V or 24V 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 is designed to handle it!
In general, suitable units are e.g. condenser micro-
phones, active DI-boxes and other special audio
devices, whose power supply is drawn from the
phantom power. Such devices are also labelled ac-
cordingly; please heed the permissible power con-
sumption (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 expli-
citly for phantom power operation, can suffer from
considerable malfunctions and damage may result
as well.
Examples of devices that may be damaged by in-
correct 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 pe-
dals etc.) whose unbalanced line output was repla-
ced by an XLR socket.
If in doubt please consult the manufacturer of the
device you are using.
5.2 Effects
The
Compact
60
3
has a built-in (internal) digital ef-
fect 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
60
3
. 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 channels 1 + 2
external effects on channels 1 + 2
right stop:
internal effects on channel 2
external effects on channel 1
