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) with a pro‐
tective 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 regis‐
tered 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.

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 Pin assignment
You can use XLR and 1/4" plugs with balanced or unbalanced wiring. In the following we will
give you an overview of the various possibilities.
XLR mounting sockets are used for signal inputs. XLR mounting plugs provide the output sig‐
nals. Drawing and table indicate the XLR pin assignment.
Balanced wiring:

4.2 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.
If you notice distortion during operation, the active speaker is overloaded. This may perma‐
nently damage the device. Always reduce the volume as soon as you hear distortion.
4.3 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’.

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.

1I / O (ON/OFF)
Use the mains switch to power the unit on or off.
2Connection for mains supply voltage
IEC chassis connector with fuse holder for operating voltage supply.
3Mains fuse
If this fuse blows, you have to replace it by a new one with same specifications.
Before you must disconnect the unit from the mains power.
4115 V / 230 V (AC)
Mains voltage selector. Make sure this selector is set correctly for the actual supply
voltage at the operating location. Use this switch only when the device is switched
off!
5INPUT
