4.1 Cabling and switching on

Before connecting to mains, please ensure that your

local mains voltage is suitable for the voltage of the

Connect all cables according to your application and

switch the amplifier 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

Domino

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 amplifier to your signal sources (guitar

pickups, microphone etc).

Turn the gain control clockwise until the red clip indi-

cator 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 am-

plifier with the necessary input.

USA, 230V in Europe).

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.

Please bear in mind: The Domino

four inputs. Four individual gain-levels may boost the

input-signal of the effect-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-

fier to your signal-sources (guitar pickup, micropho-

ne 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 redu-

cing the gain-control, then activate the attenuator

(switch pressed).

Finally set the desired overall volume level with the

master level control.
