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.
ding to your 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 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. instru-
ment) 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. Functional characteristics

5.1 Tone control

The triple-band equalizer of your Compact 60
you with an active and high quality 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 impression
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.
