4. Starting up

4.1 Cabling and switching on

Before connecting to mains, please ensure that your

local mains voltage is

suitable for the volta-

ge of the device (e.g.

120V in the USA, 230V

in Europe). The relevant

specs and safety sym-

bols are printed on the rear side of the unit.

Connect all cables according to your application

and switch the amplier on. The green power con-

trol LED indicates operational readiness.

4.2 Level adjustment

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 amplier to your signal

sources (guitar pickups, microphone etc).

Turn the gain control clockwise until the red clip

indicator 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 amplier with the necessary input.

The clip-LED indicates an overload. A short icker

is of no danger to AER devices. During operation a

short 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 Equalization

The triple-/dual-band equalizer of your Compact

603 provides you with an active and high quality

sound interaction tool that supports the natural

tone of instruments and voice whilst simultaneous-

ly oering you the possibility of a controlled accen-

tuation.

With all controls in mid position the lters are set

to produce a very pleasing and natural sound im-

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

lour lter with the eect of lowering the mids and

lifting the trebles. The tone becomes more open

and light and is especially suited for ngerpicking

techniques.

The equalization can support or soften the eect of

the colour lter and allows a dierentiated mids-

accentuation.

A: with colour-lter (switch pressed)

reduce treble to soften possible sharpness

B: without colour-lter (switch not pressed)

boost treble to brighten the sound

Note:

The active equalization of the Compact 603 eects

the signal adjustment. If you spot an intensied i-

ckering of the clip indicator, level the signal level

with the gain control (s. 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 nei-

ther 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.
