2 Safety instructions
This device is intended to be used in a sound reinforcement system. Use the device only as
described in this user manual. Any other use or use under other operating conditions is consid-
ered 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 sufficient 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!
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.

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). Do not
modify the mains cable. Failure to do so could result in electric shock/death or
fire. 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 suffi-
cient ear protectors.
NOTICE!
Risk of fire
Do not block areas of ventilation. Do not install 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.
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.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans-
port and installation.

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.
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.
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.

1[LINK]
Balanced parallel signal outputs, designed as XLR chassis plugs.
2[INPUT]
Balanced line signal inputs, designed as XLR chassis sockets.
3[Hz]
Crossover frequency control: Control to adjust the crossover frequency (40-250 Hz) of the low pass filter.
4[HIGH PASS OUT]
Balanced line signal outputs for signals above the crossover frequency, designed as XLR chassis plug.
5[SIG/LIMIT]
Limit LED (blue): Indicates overload. In this case, the level of the line input signal is too high.
6 LED
Power LED: Indicates that operating voltage is present.
7[SUB LEVEL]
Volume control.

8[GND]
If hum is caused by a ground loop, you can use this switch to disconnect the connection between the earth pin of the
device and the signal ground of the device.
9[SHAPE]
Enables the bass boost.
10 [PHASE]
If necessary, this switch shifts the phase of the subwoofer signal by 180 °. This avoids unwanted cancellation effects in
combination with other speakers.
11 [Power ON/OFF]
Mains switch. Turns the device on and off.
12 [230V~50Hz]
IEC chassis plug for the power supply.

7 Plug and connection assignment
This chapter will help you select the right cables and plugs to connect your valuable equip-
ment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a
plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short
circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hifi use.
Instrument cables with two conductors (one core plus shielding) are typical representatives of
the unbalanced transmission. One conductor is ground and shielding while the signal is trans-
mitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at low
levels, such as microphone signals and when using long cables.
In a professional environment, therefore, the balanced transmission is preferred, because this
enables an undisturbed transmission of signals over long distances. In addition to the conduc-
tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers
the signal, but phase-shifted by 180°.
