4. Starting up

4.1 Cabling and switching on

The relevant specs and safety symbols are printed
on the rear side of the unit.
Connect all cables according to your application
and switch the amplifier 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 amplifier to your signal
sources (guitar pickups, microphone etc).
Turn the gain control clockwise until the red clip
indicator flashes momentarily when playing with a
strong attack. Thus you make sure that your signal
source (e.g. instrument) provides the input-stage of
the amplifier with the necessary input
The clip-LED indicates an overload. A short flicker
is of no danger to AER devices. During operation a
short flicker 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
master level control.

5. Functional characteristics

5.1 Tone control

The triple-band equalizer of your Compact Slope
provides you with an active and high quality sound
interaction tool that supports the natural tone of in-
struments and voice whilst simultaneously offering
you the possibility of a controlled accentuation.
With all controls in mid position the filters are set to
produce a very pleasing and natural sound impres-
sion that you can „colour up" by using the colour
filter with the effect of lowering the mids and
lifting the trebles. The tone becomes more open
and light and is especially suited for fingerpicking
techniques.
The equalization can support or soften the effect of
the colour filter and allows a differentiated mids-
accentuation.

Note:
The active equalization of the Compact Slope effects the
signal adjustment. If you spot an intensified flickering of
the clip indicator, readjust the signal level with the gain
control (s. 4.2 Level adjustment).
