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). The

cording to your application and switch the amplifier

on. The green power control LED indicates operati-

onal readiness.

4.2 Level adjustment

Note: Level adjustment

By setting the level correctly we mean the signal le-

vel in one or several devices in a signal chain is neit-

her 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 unintentio-

nally 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

optimal and distortion-free performance.

Finally set the desired overall volume level with the

master level control.

5. Functional characteristics

5.1 Equalization

Note:

The active equalization of the CompactMobile

effects the signal adjustment. If you spot an inten-

sified flickering of the clip indicator, level the sig-

nal level with the gain control (s. 4.2 Level adjust-

ment).

The triple-/dual-band equalizer of your Com-

pactMobile

provides you with an active and high

quality sound interaction tool that supports the na-

tural tone of instruments and voice whilst simulta-

neously 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 im-

pression that you can „colour up" by using the co-

lour 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.
