4. Starting up

4.1 Cabling and switching on
Before connecting to mains, please ensure that your
local mains voltage is suitable for the voltage of
the device (e.g. 120V in the USA, 230V in Europe).
application and switch the amplifi er on. The green
power control LED indicates operational readiness.

4.2 Level adjustment

Note: Level adjustment
By setting the level correctly we mean the signal
level in one or several devices in a signal chain is
neither too high nor too low. This applies equally
to all circuits in a complete circuit design (EQs,
preamps etc.)
Consequently, care must be taken that no part of
the circuit is overloaded or that distortion is unin-
tentionally added to the signal.
We have carefully designed the circuit to achieve
this objective whilst also providing controls for
„manual" intervention.
First ensure, that the master level control is zeroed

(over to far left), so that when you are setting the
sound level, the signal passes through the elect-
ronics only and does not reach the loudspeaker.
By pressing the high-/low- (attn.) resp. line-/mic-
switches you can adapt the amplifi er to your signal
sources (guitar pickups, microphone etc).
Turn the gain control clockwise until the red clip
indicator fl ashes momentarily when playing with a
strong attack. Thus you make sure that your signal
source (e.g. instrument) provides the input-stage of
the amplifi er with the necessary input.

The clip-LED indicates an overload. A short fl icker
is of no danger to AER devices. During operation a
short fl icker can be accepted, to be on the safe side
you should reduce the gain slightly to achieve an
optimal and distortion-free performance.
Finally set the desired overall volume level with the
master level control.

5.1 Equalization

Note: Level adjustment
The active equalization of the
Compact Mobile 2 eff ects the signal adjustment.
If you spot an intensifi ed fl ickering of the clip in-
dicator, level the signal level with the gain control
(s. 4.2 Level adjustment).
The triple-/dual-band equalizer of your Compact
Mobile 2 provides you with an active and high qua-
lity sound interaction tool that supports the natural
tone of instruments and voice whilst simultaneously
off ering you the possibility of a
controlled accentuation.
With all controls in mid position the fi lters are set to
produce a very pleasing and natural sound impressi-
on that you can „colour up" by using the colour fi lter
with the eff ect of lowering the mids and lifting the
trebles. The tone becomes more open and light and
is especially suited for fi ngerpicking techniques.
Compact 60
The equalization can support or soften the eff ect of
the colour fi lter and allows a diff erentiated mids-
accentuation.
