5. Starting up

5.1 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.
switch the amplifi er on. The green power control LED indica-
tes operational readiness.

5.2 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 unintentionally 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 electronics 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) provi-
des 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.

6. Function description

6.1 Mute
The mute-switch mutes the device.
The mute-switch can be activated by a footswitch. The
mute-switch on the top board is than without function

6.2 Tone control

The Compact Classic pro is equipped with a bass-paramet-
ric 3-band-tone control with aff ects both input channels.
This is an active high-quality sound modifi cation on the one
hand, that allows you to change the sound of your instru-
ment specifi cally, on the other hand, you can counteract
resonance / feedback problems in the lower registers.
The bandwidth switch changes the function of the bass EQ
of wide-on narrowband.
In order to eliminate feedback and unwanted resonan-
ces select the narrowband setting (switch pressed) in
combination with a low bass knob position (possibly to the
left), then you can dampen selectively with the frequency-
control the interfering frequencies.

Note: there is no panacea for the use of an EQ, try to intui-

of instrument pickup and Enhancement requires a custom
