2 Safety instructions
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 sucient physical, sensorial, and intellectual

device only if they are supervised or instructed by a person who is responsible for their safety.
Safety
DANGER!
Risk of injury and choking hazard for children!
Children can suocate on packaging material and small parts. Children can injure themselves when handling the device. Never allow
children to play with the packaging material and the device. Always store packaging material out of the reach of babies and small
children. Always dispose of packaging material properly when it is not in use. Never allow children to use the device without supervi‐
sion. Keep small parts away from children and make sure that the device does not shed any small parts (such knobs) that children
could play with.
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 sucient ear protectors.

4 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 o. 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 elds
Loudspeakers produce a static magnetic eld. Therefore, maintain an appropriate
distance to devices that can be adversely aected or damaged by an external
magnetic eld.
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 amplier. Always follow the technical specications 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.
