Safety instructions
Intended use
This device is designed for sound reinforcement. Use the device only as
described in this user manual. Any other use or use under other operating
conditions is considered 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.
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 short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a
protective contact plug. Do not modify the mains cable or the plug. Failure to
do so could result in electric shock/death or fire. If in doubt, seek advice
from a registered electrician.
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. Do not use the
device if covers, protectors or optical components are missing or damaged.
WARNING!
Consequences of faulty mounting
Faulty mounting may lead to lethal injuries or property damage. Please ensure
that the norms and regulations valid in your country are always observed when
mounting and operating your product. In Germany: BGV C1, “Event and Production
Sites for Stage Pre‐sentations”. Only expertly trained staff may mount
speakers.
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 sufficient ear protectors.
NOTICE!
Risk of fire
Do not block areas of ventilation. Do not install 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. Only operate the device within the ambient
conditions specified in the chapter
‘Technical specifications’ of this user manual. Avoid heavy temperature
fluctuations and do not switch the device on immediately after it was exposed
to temperature fluctuations (for example after transport at low outside
temperatures). Dust and dirt inside can damage the unit. When operated in
harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should
be maintained by qualified service personnel at regular intervals to prevent
overheating and other malfunction.
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.
NOTICE!
Possible damage due to installation of a wrong fuse
The use of different types of fuses can cause serious damage to the unit. Fire
hazard! Only fuses of the same type may be used.
NOTICE!
Possible staining
The plasticizer contained in the rubber feet of this product may possibly
react with the coating of your parquet, linoleum, laminate or PVC floor and
after some time cause permanent dark stains. In case of doubt, do not put the
rubber feet directly on the floor, but use felt-pad floor protectors or a
carpet.

Installation
Unpack and check carefully there is no transportation damage before using the
unit. Keep the equipment packaging. To fully protect the product against
vibration, dust and moisture during transportation or storage use the original
packaging or your own packaging material suitable for transport or storage,
respectively.
Create all connections while the device is off. Use the shortest possible
high-quality cables for all connections. Take care when running the cables to
prevent tripping hazards.
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.
Pin assignment
You may use XLR and jack connectors with either balanced or unbalanced pinout. Below you will find an overview of the different options.
XLR connections for signal inputs/outputs
XLR panel sockets are provided for signal inputs. XLR panel plugs are provided
for signal outputs. The figure and the table show the XLR pin assignment.

| 1 | Ground |
|---|---|
| 2 | Positive signal (+) |
| 3 | Negative signal (–) |
Unbalanced pinout:
| 1 | Ground |
|---|---|
| 2 | Signal |
| 3 | Jumpered with pin 1 |
Jack plug for signal in and outputs

Tips on handling speakers
We recommend you to set up the speakers in a way, that the sound signals can
reach the audience 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 the high-grade cable to connect your equipment. Otherwise, you
won’t reach maximum sound quality.
If you notice distortion during operation, the active speaker is overloaded.
This may permanently damage the device. Always reduce the volume as soon as
you hear distortion.
Hanging the speaker box
To hang the speaker box on special mounting devices (aka ‘flying’), the top of
the box offers 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’.
Using an additional loop on the back of the box, it is possible to tilt the
box. This additional loop must not solely be in charge to secure the entire
suspended weight.
