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.
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.
CAUTION!
Risk of injury due to heavyweight Due to the heavyweight of the device, at
least two persons are required for transport and installation.
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!
Possible staining
The plasticiser 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.
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.
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.
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 decreed 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 distortion.
Connections
- [FULL RANGE INPUT] Lockable NL4 connector for signal input (1+/1–).
- [FULL RANGE THRU] Lockable NL4 output connector (1+/1– looped-through) to connect another speaker.
- Screw terminal input
