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
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.
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, 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.
