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
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!
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.
WARNING!
Possible hearing damage due to operating the device at a high volume!
The device can produce volume levels that, when operated at a high volume, may cause temporary or permanent hearing impair‐
ment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage. Avoid operating the device
at excessively high volumes over an extended period of time. 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 adequate ear-mus.

WARNING!
Risk of injury from falling speakers that were inadequately secured!
If speakers are not properly secured when mounted, they can cause severe injury and considerable damage by falling. Always secure
portable sound systems (speakers) with two independent safety devices, such as safety cables.

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 to adjacent devices due to magnetic elds.
Speakers generate a static magnetic eld. This magnetic eld can aect other
neighbouring units and in unfavourable cases damage them.
Ensure that speakers are always a sucient distance away from sensitive equip‐
ment that may be aected by an external magnetic eld.

WARNING!
Risk of injury from falling speakers that were inadequately secured!
If speakers are not properly secured when mounted, they can cause severe injury
and considerable damage by falling.
Always secure portable sound systems (speakers) with two independent safety
devices, such as safety cables.
1. Screw the ring eye into the top of the speaker.
2. Thread the wire rope through the ring eye and the ceiling suspension.
3. Lock the wire rope with two snap hooks.
4. Attach the cables of the speaker to the wire rope with suitable cable ties.

2. If required, screw the base plate to the ground spike. Then screw the base plate to suit‐
able oor material (e.g. wood).
3. Screw the speaker to the stud of the bracket.
4. Route the cable of the amplier through the device cover and attach the device cover to
the speaker.

4.3 Tips on handling speakers
We recommend you to set up the speakers in a way, that their sound signals can reach the
audience unobstructedly.
Always use high grade cables 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 all equipment
involved!
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 as soon as you notice
distortion.
