INSTALLATION
The subwoofers can be placed as desired. For convenient transport, matching castors are available as
accessory. With the M20 flange and a distance tube (accessory), it is possible to mount another speaker
system on top of subwoofers. For this, insert a distance tube of 35 mm into the flange on the upper side of
the subwoofers; then fasten the satellite speaker on top.
Notes
• Always install the speaker at a solid, plane, anti-slip, vibration-free, oscillation-free and fire-resistant
location. Before installing the system, make sure that the installation area can hold a minimum point load of
5 times the system's load (e.g. weight 20 kg - point load 100 kg). The speaker must never be installed
higher than 100 cm without secondary attachment.
• Always install speaker systems in a way that a minimum distance of three meters to the audience is kept.
This is the only way to avoid hearing damage for unreasonable listeners. Block the area in front of the
speaker systems with appropriate means.
• Extreme levels like feedback, bass-hum or the beats of a dropping microphone can destroy the
loudspeakers within very short time and produce immediate hearing damage. Such extreme levels must be
avoided at any rate. We recommend using appropriate equalizers and compressors/limiters.
• For transport, the subwoofer box features two carrying handles. The speaker system should be carried
without force by two persons of the same size. Carrying the speaker system as one person alone should be
avoided as the high weight and the strain could lead to back damages and torsions. Please note that all
speaker systems with more than 25 kg weight must be transported with two persons.
• Satellite systems must only be installed on a plane area with a maximum inclination angle of 5°.
• The stand has to be installed out of the reach of people. An unintended movement of the load has to be
avoided - also in case of fire!
• Depending upon the individual installation spot, all necessary measures against movement and for
securing the standing safety have to be taken.

MAKING THE CONNECTIONS
Switch off the subwoofer box and the units to be connected before making or changing the
connections.
Connecting the Signal Source
As signal source, audio units with line level output (e.g. mixer, preamplifier) can be connected to the inputs
via XLR plugs, balanced and unbalanced.
= left channel).
A good cable run improves the sound quality remarkably. Signal cables should be short and direct, since
high frequencies will mostly be absorbed if cables are unnecessarily long. Besides that a longer cable may
lead to humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables. In
order to obtain highest sound quality, only use high-quality cables for connecting the devices. Make sure that
the cables are properly fixed.
The inputs are designed for stereo signals (R = right channel, L
