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.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or fire. If in doubt, seek advice from a regis‐
tered 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 cover the device nor any ventilation slots. Do not place 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 check carefully 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.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
WARNING!
Risk of injury caused by falling objects
Make sure that the installation complies with the standards and rules that apply
in your country. Always secure the device with a secondary safety attachment,
such as a safety cable or a safety chain.

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.

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 amplifier. Always follow the technical specifications 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.

4.2 Pin assignment
You can use XLR and 1/4" plugs with balanced or unbalanced wiring. In the following, we will
give you an overview of the various options.
XLR chassis sockets serve as signal inputs, XLR chassis plugs serve as signal outputs. Drawing
and table indicate the XLR pin assignment.
Balanced wiring:
1 Ground, shielding
2 Positive signal (+)
3 Negative signal (–)
XLR connections for signal in
and outputs

1 Mains switch POWER
Turns the unit on and off.
2GND LIFT button
If a ground loop is causing hum you can use this key to break the connection between the earth pin of the device and
the signal ground in the device. The switch will only have an effect when using balanced connection cables.
3ON LED
This LED lights up green when the device is turned on and power supply is present.
4 LED SIGN/LIMIT
This LED lights up green when an input signal is present.
This LED lights up red when the internal output signal is being limited (due to excessive input signal level!).
5 Rotary control MIC GAIN
MIC IN input signal gain control to adapt the active speaker to the characteristic of the used microphone.

6 Rotary control LOW
Controller for attenuating or raising the low frequencies.
7 Rotary control HIGH
Controller for attenuating or raising the high frequencies.
8 Rotary control LINE LEVEL
LINE input signal gain control. Turn the knob, starting from zero position, clockwise or counterclockwise to increase
or decrease the volume of this input.
In zero position, the signal is fully attenuated. In right end stop position, the signal is processed without any attenua‐
tion.
