4. Starting up

4.1 Cabling and switching on

Before connecting to mains, please ensure that your
printed on the rear side of the unit.
Connect all cables according to your application
and switch the amplifi er on. The green power con-
trol 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

Finally set the desired overall volume level with the

5. Functional characteristics

5.1 Tone control

The triple-band equalizer of your Compact 60
provides you with an active and high quality sound
interaction tool that supports the natural tone of in-
struments 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 impres-
sion 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.
The equalization can support or soften the eff ect of
the colour fi lter and allows a diff erentiated mids-
accentuation.
