4 Installation
Unpack and carefully check that there is no transportation damage before using the unit. Keep
the equipment packaging. To fully protect the device against vibration, dust and moisture
during transportation or storage use the original packaging or your own packaging material
suitable for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
WARNING!
Risk of injury caused by falling objects
Make sure that the installation complies with the standards and rules that apply
in your country. Always secure the device with a secondary safety attachment,
such as a safety cable or a safety chain.

NOTICE!
Possible property damage by magnetic fields
Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate
distance to devices that can be adversely affected or damaged by an external
magnetic field.
NOTICE!
Use of stands
When mounting the device onto a stand, ensure that the stand is in a safe and
stable position and that the weight of the device does not exceed the maximum
permissible load capacity of the stand.

4.1 Tips on handling speakers
We recommend you to set up the speakers in a way, that the sound signals can reach the audi‐
ence unobstructedly. It will often be helpful to mount the speakers on tripods. Thus, the sound
will be evenly spread with maximum range throughout the audience area.
Always use high grade cable to connect your equipment. Otherwise you won't reach max‐
imum sound quality.
For optimum results both impedance and power handling of the speakers must match the
requirements of the amplifier. Always follow the technical specifications of the speakers! The
overall impedance of the connected loudspeakers must not deceed the minimum output
impedance of the amp. The amps max. RMS output power should be 50 % above the power
handling capacity of the connected speakers.
If you notice distortion during operation, either the amp or the speaker is overloaded. This may
permanently damage the amp or the speaker. Always reduce the volume when you hear dis‐
tortion.

4.2 Hanging the speaker box
To hang the speaker box on special mounting devices (aka ‘flying’) both sides of the box offer
built-in Aeroquip or fly tracks. In these tracks safety eyelets (double studs) can be screwed or
latched. Check the secure connection of the safety eyelets with the box carefully, before you
use it in ‘flying mode’.

4.4 Setup options
The Achat 208 HL (left-hand version) and the Achat 208 HR (right-hand version) are always
operated in pairs. The side where the horn is located is marked with a grooved line and with
"AIM". When viewed from the front, the grooved line shows the vertical orientation of the horn
(8° downwards).
This allows you to see where the main radiation axis hits the ground and you can determine
the range of the box via the height in which it is operated.
In single and double block setups, the lines always point to the stage centre.
In all applications, the use of additional woofers covering the range from low bass frequencies
to the crossover frequency is recommended. Due to the achievable level of the Achat 208, at
least a double 18“ woofer should be used for each Achat 208.
The Achat stack board is recommended as an adapter plate that can be put on all woofers of
the Achat series (from Achat 115 SUB onwards) and engages there.
In double or quad block configurations, two Achat 208 each are set on top of one another. To
this end, they are fixed together with the optionally available link bars.

When you spread the two centre loudspeakers by approximately 10 cm, you will get a more
even acoustic diffusion (about 100° horizontally).
When the box walls of the the two centre loudspeakers are located directly to one another,
maximum coupling with a high concentration of the medium frequencies is achieved.
