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.
DANGER!

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 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.

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 re. If in doubt, seek advice from a registered 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 sucient ear protectors.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for transport and installation.
NOTICE!
Risk of re
Do not block areas of ventilation. Do not install the device near any direct heat source. Keep the device away from naked ames.

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 specied in the chapter
‘Technical specications’ of this user manual. Avoid heavy temperature uctuations and do not switch the device on immediately
after it was exposed to temperature uctuations (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
qualied 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 re.
NOTICE!
Possible damage due to installation of a wrong fuse
The use of dierent types of fuses can cause serious damage to the unit. Fire hazard! Only fuses of the same type may be used.

The plasticiser contained in the rubber feet of this product may possibly react with the coating of your surface and after some time
cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the surface and use a suitable underlay if neces‐
sary, i.e. felt-pad oor protectors or similar.

distance to devices that can be adversely aected or damaged by an external
magnetic eld.

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.

2 IEC chassis plug for power supply with fuse holder
3[OUTPUT]
Signal output to connect another mixer, designed as XLR chassis plug
4[HIGH CUT]
Control for adjusting the low-pass lter. This sets the upper cut-o frequency for the signal going to the built-in
amplier.
5[LIMIT]
The LED lights up when the amplier's input level is too high. In this case, reduce the level of the input level.
6[INV]
If necessary, this switch shifts the phase of the subwoofer signal by 180 °. This avoids unwanted cancellation eects in
combination with other speakers.
7[ACTIVE]
The LED indicates that the device is switched on.
