4.2 Level adjustmen

First ensure that the volume level control is in zero

position (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. Turn the level control of each input

with incoming signal up to a short flicker of the

clip indicator. 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 level slightly to achieve an

optimal and distortion-free performance.

Finally set the desired overall volume level with the

volume level control.

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.
