are built for maximum quality reproduction and audio perfection. With the AX-series
you have selected a precise, high-resolution speaker system that allows you to both
evaluate and enjoy audio recordings. This monitor meets the highest expectations in
sound quality and craftsmanship.
This manual is intended to provide you with information about your new ADAMs. It
contains important information regarding safety, setting up, handling, and
warranty. We suggest that you read these sections carefully to ensure easy set up and
prevent potential problems.
Our AX near- and midfield monitors are perfectly suited for a wide variety of stereo and
multi-channel professional applications including small control rooms, desktops, mobile

no-compromise sound reproduction and a small footprint is required.
Each loudspeaker of the AX range consists of a two-way ported active system that uses
ADAM’s proprietary X-ART folded ribbon tweeter ensuring full compatibility with the
latest expanded high frequency resolution media formats along with a conventional
bass/midrange driver. For each section there is individual amplification with continuous

2. Quick Start
2.1 Important Information for set up
After having unpacked your loudspeaker, please allow the system to acclimate to the
temperature of the room for approximately an hour.
It is important to ensure the speakers sit firmly on a solid surface!
We recommend that you retain the original packaging, as it is the best way to guarantee
safe transportation should the need to do so arise.
Please note that the loudspeakers will take some break-in time to achieve optimum
sonic performance.
2.2 Quick Start
a) Before connecting the loudspeakers to your audio components and the power source
make sure that both the loudspeakers and your audio source are switched off and set
the level controls fully counterclockwise.
b) There are two options of connection:
Basic active speaker use. Connect your sound source or mixing console to the speakers.
Use either the RCA (unbalanced) or the XLR (balanced) connectors. You will find the
connector wiring printed on the speaker’s rear panel (for further information, see 3.1).
Stereo Link. If you want to use the Stereo Link (controlling the overall volume by one
control), please see 3.2 (A3X and A5X only).
c) Check if the specified voltage matches the voltage of the power supply you use. If this
is not the case do not connect the loudspeakers to a power source! Please contact
your local dealer or national distributor.
If the voltages match, use the included power cables to connect the loudspeaker to
the AC sockets.
d) Switch on the main on/off switches on the front panel of the loudspeakers.
e) Make sure that the line out level (volume) of your stereo is either at a low level or all the
way off. Then, switch on your audio system.
f) Turn on your source of music and adjust the volume carefully.
A77X only:
Operational readiness of the A77X tweeter
Please note that for technical reasons (i.e. starting up the amplifier, stabilization of the operating
voltage) the tweeter of the A77X starts up slightly delayed.

3.1 Basic connections
For the basic speaker connection, please use
mono XLR or RCA cables. In most professional
applications XLR will be the best choice, while
RCA is more common in HiFi applications. Each
one of the two loudspeakers has to be connected
to one channel of the sound source.

3.2 The Stereo Link (A3X and A5X only)
If you wish to use the Stereo Link that allows adjustment of the volume of both
loudspeakers with a single master control, please proceed as follows:
a) First, connect Speaker 1 (that is supposed to control the overall volume) to your
preamplifier, sound source, etc. by using one stereo or two mono RCA leads. Please
note that the Stereo Link does not work with XLR.
When connecting your speakers via RCA please make sure the white (or black) RCA
plug which leads the left stereo channel is connected to the “Unbalanced In” and the
red RCA plug (that leads the right stereo channel) is connected to the “Stereo Link
Input” of the left speaker, if this is the master speaker you want to control the overall
volume with.
If the right speaker shall be the master please connect the red RCA plug (the right
stereo channel) to the “Unbalanced In” and the white (or black) RCA plug for the left
stereo channel to the “Stereo Link Input” of the right speaker.
b) Secondly, connect the “Stereo Link Output” of Speaker 1 to the “Unbalanced In” of
Speaker 2 by using the provided (or another) mono RCA cable.
Please note:
On the front side of the unit functioning as master, a corresponding green LED will
illuminate as soon as a mono RCA plug is connected to the Stereo Link output.
Unlike the common ‘master-slave-configuration’, any A3X or A5X that is connected accordingly
can function as either a master or a slave unit.
For an equal volume level of both speakers please make sure that the volume knob of speaker 2 is
snapped in the middle position.

4. Speaker Placement
Please make sure that there are no obstacles in the way from the monitor to your ears.
You should be able to see the speakers completely.
4.1 Vertical set up
The AX-series have been designed for
a vertical set up (except the A77X). The
speakers must be positioned on a solid
surface or a stand. Please note that
vibrating parts of nearby objects can
mask the sound.
A3X
4.2 Horizontal set up
If you choose to use your speakers in horizontal position as indicated below, please
make sure that the set up is mirrored/symmetrical, i.e. that the tweeters both face
either the outwards or inwards. This is crucial for a precise stereo signal.

4.3 The A77X in a stereo setup
The A77X has been designed for a horizontal set up. Please note that for a stereo
setup consisting of two A77X monitors there are two different versions available,
A and B (see label on the rear panel). The reason for the A and B versions is that
although both 7“ woofers are operating in the bass domain down to 38Hz, one
woofer is gradually faded out between 150Hz and 400Hz. This means that only one
woofer reproduces the actual midrange in order to prevent interferences between
the two drivers. For the best stereo image in a setup with two A77X it is vital to
place both speakers the A/B or the B/A way, meaning that both midrange woofers
should either face the inner side or both the outer side of the stereo setup mirrorsymmetrically. Should you wish to use the A77X as a center speaker in a surround
setup of course the A and B versioning is of no importance.
4.4 Tweeter at the height of ears
The Tweeter should be positioned approximately at the height of your ears. In
case you need to position the speaker in a significant lower or higher position, the
monitor should be angled accordingly.
4.5 The Stereo Triangle
If the loudspeaker is going to be used for stereo
applications, the optimum listening position should
be at the top of an imaginary equilateral triangle with
the two loudspeakers to be placed at the other two
points of this triangle. The loudspeakers should be
aligned with the listener’s position.

4. Speaker Placement
4.6 Surround Placement
Speaker positioning for multi-channel stereo purposes is ideally based on a circle
with speakers placed at 0° (Center), 30° (Front Right), 110° (Rear Right), 250°
(Rear Left), 330° (Front Left), with the listener being the circle’s center (Radius
between 0.7-2.0 m). This ITU recommended configuration may vary depending on
the purpose of the control room (music or film). However, it is recommended to
create a symmetrical listening position with the front side and surround speaker
pointing to the listener’s ear.
A3X/A5X only:
4.7 Stand/Wall Mounting
On the A3X and the A5X speakers you will find two M6 (6 mm) metric screw
threads for stand/wall mounting on the rear side. Further equipment for mounting
is also available. Please contact us for more information.
