expanded high frequency resolution media formats, and a conventional bass/

midrange driver below the crossover frequency of 2.8 kHz. Each section uses

an individual amp with continuous output of up to 25 Watts (RMS).

2. Quick Start

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.

Quick Start

Before connecting the loudspeakers to your audio components and the

power source make sure that both the loudspeakers and your audio system

are switched off and set the level controls fully counterclockwise.

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.

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.

Switch on the main on/off switches on the front panel of the loudspeakers.

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.

Turn on your source of music and adjust the volume carefully.

2.2

English

3. Connecting the Speakers

Basic active speaker connection

For the basic active 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.

The Stereo Link

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:

First, connect Speaker 1 (that is supposed to control the overall volume) to

your preampliﬁer, sound source, etc., using a stereo RCA (*1) cable.

Second, connect Speaker 2 to Speaker 1 via the Stereo Link output of

Speaker 1 and the Analog Input of Speaker 2. Please use the provided (or

another) mono RCA cable.

Please note:

On the front side of the unit functioning as master, a corresponding

white LED will illuminate as soon as mono RCA is connected to the

Stereo Link output.

Unlike the common ‘master-slave-conﬁguration’, any A3X 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.

Vertical set up

Hoizontal 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.

or so:

4.2

The A3X has been designed for a

vertical set up. The speakers must

be positioned on a solid surface or

a stand.

Please note that vibrating parts of

nearby objects can mask the sound.

4. Speaker Placement

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.

ﬁg 5: Tweeter at height of ears / speaker angling

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 should be placed at the other two points of this

triangle (see ﬁg. 6).

The loudspeakers should be aligned with the listener’s position.

4. Speaker Placement

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.

The distance to the surrounding walls should be at least 40 cm to avoid early

reﬂections, which can degrade the sound.

ﬁg 7: Surround set up

Stand/Wall Mounting

On the rear side, you will ﬁnd two M8 (8 mm) metric strew threads for stand/

wall mounting. Further equipment (e.g. Omnimount) for mounting is also

available.
