2 Safety instructions
This device is intended to be used in a sound reinforcement system. Use the device only as
described in this user manual. Any other use or use under other operating conditions is consid‐
ered to be improper and may result in personal injury or property damage. No liability will be
assumed for damages resulting from improper use.
This device may be used only by persons with sufficient physical, sensorial, and intellectual
abilities and having corresponding knowledge and experience. Other persons may use this
device only if they are supervised or instructed by a person who is responsible for their safety.
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like) from
the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.

DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord). Do not
modify the mains cable. Failure to do so could result in electric shock/death or
fire. If in doubt, seek advice from a registered electrician.

CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.
NOTICE!
Risk of fire
Do not cover the device nor any ventilation slots. Do not place the device near
any direct heat source. Keep the device away from naked flames.

NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and
strong vibrations.
NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.
Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

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.

CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.
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 Mounting
Due to its mechanical structure, the device can either be individually put on the ground or
hung, or arranged to line arrays of variable size. The units can be joined together using the
built-in fasteners without any additional parts. For easy, flexible and secure mounting, the
flying frame (item number 313502) is available as optional accessories. This section shows how
easy the assembly is.
To the left and right of the front panel, a safety pin is attached, allowing you to stably connect
the unit to the one directly above it. There is a foldable vertical latch on the rear panel. This
latch fits into the U-rail of the device mounted below, which has a series of numbered bores.
Attach the latch of the upper unit to the U-rail of the underlying device with a safety pin. By
selecting the hole, you can set the desired angle of inclination. Figure and table show the
mechanical parts on the rear side and its function.

1 Vertical latch of the overlying unit (in longitudinal and lateral view).
2 Securing bore in the vertical latch. Use this bore when the vertical latch of the device is not folded down, so for single
installation or for the lowest unit in a system.
3 Bore for angular steps of 1 °.
4 Bore for angular steps of 0.5°.
5 U-rail of the device (side view).
6 Clearance bores for odd-numbered angles.
7 Clearance bores for even-numbered angles.
8 Use this bore of the U-rail when the vertical latch of the device is not folded down, so for single installation or for the
lowest unit in a system.

1. Attach the flying frame left and right at the front panel of the top unit.
2. Secure the flying frame with the locking pins that are attached to the top unit.

3. Position the vertical latch of the flight frame in the U-rail of the top unit.
4. Secure the latch in the correct position with a safety pin at the U-rail.
5. For flying operation, mount a shackle on the flying frame. It must be located directly
above the centre of gravity of the entire system. In the figure, the centre of gravity is
marked by ‘C’, the arrow shows the correct position of the U-shackle for this installation
situation.
The flying frame can also be used as a framework for positioning of a device on the floor. In
this case, turn the unit by 180° upside down and attach it to the flying frame, as described in
chapter Installation of a flown system. Then turn the whole thing around and put the flying
frame with the rubber feet on the ground.

Usually, several units are so installed to a line array, that they are arranged arcuate. The figure
alongside shows an example of how four elements can be combined into a system that stands
on the ground (ground stack). In the figure, the centre of gravity is marked by ‘C’.
In a ground stack, no more than four elements with maximum angulation may be
used.
In flying operation, the shackle must be mounted just above the centre of gravity of the entire
system.
