1. Introduction
Welcome to B!
Thank you for purchasing the Domino2.A of our acou-
stic-line-series.
To obtain maximum enjoyment from your amplier
please read this manual carefully before using your
Domino2.A.
Based on our Compact602-acoustic-system we have
developed the Domino2.A a 100-watt system that com-
bines the excellent tone of the Compact with increased
power and higher eciency.
The Domino2.A is – of course – dynamically controlled
and equipped with two parallel power-ampliers, two
8“-twin-cone loudspeakers, 1“-neodym tweeter for ad-
ditional headroom, 4 inputs with mute-option (inputs
3 and 4 with shared equalization), channel mute, in-
sert-link feature and AER-32/24-bit-digital-eects with
16 presets.
Read on and have fun using your Domino2.A!

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.
Please bear in mind: The Domino2.A is equipped with
four inputs. Four individual gain-levels may boost the
input-signal of the eect-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-
er 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.
4. Starting up
4.1 Cabling and switching on
Before connecting to mains, please ensure that your
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-
ted on the rear side of
the unit.
Connect all cables according to your application and
switch the amplier 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 amplier to your signal sources (guitar
pickups, microphone etc).
Turn the gain control clockwise until the red clip indi-
cator 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 am-
plier with the necessary input.

5. Functional characteristics
5.1 Mute
The mute switch turns the appliance to mute as requi-
red. The function can also be activated by a standard
footswitch (on/o switch).
5.2 Equalization
The triple-band equalizer of your Domino2.A provides
you with an active and high quality sound interaction
tool that supports the natural tone of instruments and
voice whilst simultaneously oering you the possibili-
ty of a controlled accentuation.
With all controls in mid position the lters are set to
produce a very pleasing and natural sound impression
that you can„colour up“ by using the colour lter with
the eect of lowering the mids and lifting the trebles
(-3 dB at 700 Hz, +10 dB at 8kHz). The tone becomes
more open and light and is especially suited for nger-
picking techniques.
The equalization can support or soften the eect of
the colour lter and allows a dierentiated mids-ac-
centuation.
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
colour bass middle treble
colour bass middle treble
Note:
The active equalization of the Domino2.A eects the
signal adjustment. If you spot an intensied ickering
of the clip indicator, level the signal level with the gain
control (s. 4.2 Level adjustment).
5.3 Eects
The Domino2.A has a built-in (internal) digital
32/24-bit-AER-eect processor, with the select-switch
you can choose between 16 diverging presets (s.
chart below).
The return-control determines the intensity of the
internal eects (left stop = no eect), the e. send-
controls level the ratio of eect and original signal
per channel.

Furthermore an additional eects unit (external ef-
fect) may be connected to the Domino2.A. For this
purpose use the send and return sockets on the rear
side of the amplier (send goes to input, return to
the output of the external eects device). The inten-
sity of the eect is adjusted at the external eects
unit.

5.4 Phantom power
Microphones requiring 48V phantom power can be
directly connected to the XLR sockets of channels 2
and 3/4. The phantom power can be switched on and
o via the 48V-switch.
The jack sockets of channel 1 and 3/4 can additio-
nally be supplied 15V-Phantomspeisung by an in-
ternal jumper.
Please note: For these alterations the device must
be opened, therefore only qualied service person-
nel may carry out the modications concerning the
activation of phantom power.
5.5 Stereo-Simulation
The Domino2.A is mono – thus L-out and R-out are
carrying the same output-signal. You can use these
sockets to connect additional active AER fullrange-
systems (e.g. AG 82, CX 8, AS Q8, AS 281), whose levels
are adjusted by the pre master-control independent
of the overall volume (master) of your Domino2.A. By
activating the stereo-simulation (stereo sim.-switch
pressed), a stereo-like, wider sound impression is ge-
nerated.
On stage (Domino2.A as monitor) the sound remains
unchanged..
General Note: Use of 48V or 24V phantom
power
(Phantom power = remote supply, here: powering
an audio device via the connected audio line)
Turn on the phantom power only if the unit con-
nected to the XLR sockets of channels 2 and 3/4 is
designed to handle it!
In general, suitable units are e.g. condenser micro-
phones, active DI-boxes and other special audio
devices, whose power supply is drawn from the
phantom power. Such devices are also labelled ac-
cordingly; please heed the permissible power con-
sumption (max.10mA).
High-quality dynamic microphones with a balanced
signal need no phantom power, but can handle it
anyway.
Other devices, which have not been designed expli-
citly for phantom power operation, can suer from
considerable malfunctions and damage may result
as well.
Examples of devices that may be damaged by in-
correct application of phantom power include:
Low-cost dynamic microphones with a mono jack-
plug (unbalanced signal) that were tted afterwards
with an XLR connector.
Audio devices with a balanced XLR output (e.g. DI-
boxes, eects devices, instrument preamps with
a DI output etc.) which are not protected against
phantom power applied to their XLR output. (The
DI connectors on AER products are protected
against applied phantom power.)
Other audio devices (such as preamps, eects pe-
dals etc.) whose unbalanced line output was repla-
ced by an XLR socket.
If in doubt please consult the manufacturer of the
device you are using.

5.6 Insert
The insert-loop is an in-/output on a stereo-socket to link dierent eect-de-
vices (EQ, compressor etc.) in serial mode with tip = send (input) and ring =
return (output). This conguration allows several more applications, such as:
1. use as additional line-output
2. use as additional line-input
3. link between two or more AER-amps with insert-feature (AG8, Domino,
Compact ClassicPro)
For each of these applications you’ll need the appropriate cable connection,
e.g. use as line-output: stereo-jack (tip and ring = hot, sleeve = ground) to
mono-jack.
The particular AER-link-application (s. no. 3 - link between AER-amps) is re-
presented on page 11. In link-operation it is assured, that the signals of all con-
nected amps are hearable on all devices, even with dierent eect settings.
You just have to be aware, that the dierent levels depend on each other.
This setting (in combination with active loudspeakers, pre master-function)
works as a complete and easily operated reinforcement/monitor system.

Master adjusted such that the rated output power (limiter
disabled) or, alternatively, the rated output voltage at line
out is obtained.
Output voltages refer to rated conditions as stated above.
Min. input voltage: Input voltage required for rated output
power (limiter disabled) with gain and master fully
clockwise
Max. input voltage: Input voltage that does not cause more
than 1% THD+N, suitable control settings provided
THD+N: Total harmonic distortion + noise at input and
output levels 10 dB below rated conditions.
Equivalent input noise voltage: Noise voltage at speaker
output divided by gain of amplifier. gain of input under
test fully clockwise, master fully clockwise, gain of unused
inputs minimal. Input shorted, B = 22 Hz … 22 kHz
Residual noise: Noise of an output when its level control is
set to minimum.
Dynamic range (power amp): Ratio of rated output voltage
to residual noise voltage with master fully anticlockwise.
Options: The following options are available by internal
jumper settings.
1) Channels 1 and 4 can have 15 V phantom power
enabled at “ring” of jack socket.
Caution: This option is
not overload-protected. Improper use may cause
malfunction or damage.
2) Gain of channels 2 and 3 can be reduced by 3 dB to
allow for more headroom.
3) Ext. effect send level can be made dependent on the
send controls of each channel.
4) Internal effect can be disabled for each channel.
5) Aux input signal can be disconnected from DI out.
6) Internal effect can be added to DI out.
Specifications and appearance subject to change without
notice.
