5.2 Effects

Internal Effects

The Compact XL has a built-in (internal) digital effect
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 effects-level control determines the intensity of
the effect (fully anticlockwise = no effect).
In addition, the effect is assigned to one or both chan-
nels by the effects pan control (see below).
External Effects
Furthermore an additional effect unit (external effect)
may be connected to the amplifier. For this purpose
use the send and return sockets on the rear side of the
amplifier (send goes to the input, return comes from
the output of the external device).
The intensity of the effect is determined by the
external effects unit.
The external effect loop works in parallel mode.
A parallel loop is intended to add the effect compo-
nent (for example, reverb) to the original signal.
pan
Using the effects pan control you can blend both
effects continuously into the amplifier's channels:
Left stop: internal effect on channel 1
external effect on channel 2
Center pos.: internal effect on channel 1 + 2
external effects on channel 1 + 2
Right stop: internal effect on channel 2
external effect on channel 1
Avoid distorted effects
Clipping in the internal or external effect unit may not
be indicated by the clip light. If distortion is audible
in in the effect, reduce the gain controls until the dis-
tortion disappears. Subsequently you can restore the
previous volume with the master control.

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.
Suitable footswitches are on-off toggle switches,
which are turned on by stepping once, and turned off
by stepping once again.

5.4 Phantom power

48 V phantom power at microphone input
Microphones that require 48 V phantom power
(P 48) can be connected directly to mic in by an XLR
plug. The amplifier is supplied with 48 V phantom
power enabled, but it can be disabled by an internal
jumper (see note).
When connected by a jack plug, the 48 V phantom
power is not applied. Use the jack connection for mi-
crophones that must not be connected to phantom
power.
Please also read the general notes on
phantom power.
Please note: For the alteration mentioned above,
the device must be opened, therefore only qualified
personnel 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 accordingly. Such preamps are connected
to input 1 by a stereo jack cable.
The phantom power can be switched on by the 9 V
switch. The yellow indicator lamp then lights up.
Sources that don't need phantom power should al-
ways 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 in-
put 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
explicitly for phantom power operation can
suffer from considerable malfunction and damage
may result as well.
In case of uncertainty please consult the
manufacturer of your accessories.
We wish you lots of fun playing your Compact XL!
