4. Starting up

4.1 Cabling and switching on

Before connecting to mains, please ensure that your

ted on the rear side of the unit.

Connect all cables according 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 cir-

cuits 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 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. instrument) provides the input-stage of

the amplifi er with the necessary input.

local mains voltage is

suitable for the voltage

of the device (e.g. 120V in

the USA, 230V in Europe).

The relevant specs and

safety symbols are prin-

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.

Please bear in mind: The Domino

four inputs. Four individual gain-levels may boost the

input-signal of the eff ect-section and thus cause dis-

tortion. This distortion can only be heard and in this

case it is imperative, to reduce the gains to elminitate

the distortion.

With the line/mic-switch you can adjust your ampli-

fi er to your signal-sources (guitar pickup, microphone

etc.). The attn.-switch (attenuator de-/activation),

as well as gain-control and line/mic-switch, helps

with the signal-matching. Start without attenuator

(switch not pressed). Should the input-signal be too

strong and you can't avoid clipping even by reducing

the gain-control, then activate the attenuator

(switch pressed).

Finally set the desired overall volume level with the

master level control.
