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 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.

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 high­quality 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.

Pin assignment

You can use XLR plugs with balanced or unbalanced wiring. The following will give you an
overview of the various possibilities.

XLR mounting sockets are used for signal inputs. An XLR mounting plug provides the line out
signal. Drawing and table indicate the XLR pin assignment.

Balanced wiring:

1 Ground, shielding
2 Positive signal (+)
3 Negative signal (–)

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.

1 Mains fuse

If this fuse blows, you have to replace it by a new one with same specifications.
Before you must disconnect the unit from the mains power.

2 Connection for mains supply voltage

Make sure that the mains switch (3) is in OFF position (O), before connecting the
mains power cable here.

3 I / O (ON/OFF)

Use the mains switch to power the unit on or off.

4 NL4 socket (SPEAKER OUTPUT)

Lockable NL4 connector for the connection of another passive speaker box.

5 XLR socket (LINE OUTPUT)

You can connect the line input of other active monitors to this line output.

6 XLR socket (LINE INPUT)

You can connect the output of other line level sources (e.g. a CD player or the line
out of another active monitor) to this line input.

7 XLR socket (MIC INPUT)

Here you can connect microphones or the output of other sources with mic level.

8 Bass control (LF)

Turn this control clockwise to increase the low frequencies. Turn it counterclock‐
wise to attenuate these frequencies.

9 Mid control (MF)

Turn this control clockwise to increase the mid frequencies. Turn it counterclock‐
wise to attenuate these frequencies.

10 Treble control (HF)

Turn this control clockwise to increase the high frequencies. Turn it counterclock‐
wise to attenuate these frequencies.

11 Volume control (LINE VOL)

Turn this control clockwise to increase the volume of the line input signal. Turn it
counterclockwise to reduce the volume. Caution: First reduce the volume to min‐
imum, before switching the unit on and transmitting signals. Then set the desired
volume. Make sure, that the PEAK indicator (13) does not light up.

12 Volume control (MIC VOL)

Turn this control clockwise to increase the volume of the microphone input signal.
Turn it counterclockwise to reduce the volume. Caution: First reduce the volume to
minimum, before switching the unit on and transmitting signals. Then set the
desired volume. Make sure, that the PEAK indicator (13) does not light up.
