INSTALLATION

Please note: when using the speaker-system in public or industrial areas, a series of safety instructions
have to be followed that this manual can only give in part. The operator must therefore inform himself on the
current safety instructions and consider them.

Inputs

A good cable run improves the sound quality remarkably. Input cables should be short and direct, since high
frequencies will mostly be absorbed if the 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.

Outputs

Via the Aux Outputs, you can connect further PA mixing amplifiers.
Connect your passive speaker-systems the 4-16 Ω output and the Com-output.
Attention: Consider the polarity of the speakers when installing your system. "Positive" and "negative"
terminals on the amplifier must be connected to the corresponding "positive" and "negative" terminals on the
speakers.
1. Connect one end of your speaker wire to the 4-16 Ω-output on your amplifier. Connect the other end of
your speaker wire to the negative input terminal of the speaker-system.
2. Connect one end of your speaker wire to the Com-output on your amplifier. Connect the other end of your
speaker wire to the positive input terminal of the speaker-system.
Choosing appropriate connection cables
The speaker-system must only be connected via a sufficiently dimensioned cable. Too thin cables lead to
cable heatup or enormous power loss and loss in sound-quality.
For all speaker-systems up to 400 Watts, we recommend a cable diameter of 2.5 mm², for all other speaker-
cables 4 mm².
A high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin
cables will influence the damping factor and thus the low frequencies in a negative way. In order to
safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be, the
thicker it should be.
In this respect, a damping factor of 200 will be reduced to 47 (8 Ohms) when using a 10 m long, 2.5 mm²
speaker cable. The power loss at 8 Ohms is 1.63 %, at 4 Ohms 3.25 % and at 2 Ohms even 6.5 %.
The maximum cable length is 30 meters!
Installing the speaker-cables
Connect the speaker-systems among each other using the inputs and outputs. Connect the cable of the first
speaker-system with the Speaker-socket Output CH-1 and Output CH-2 of the amplifier. The signal will be
transmitted to the individual speaker-systems.
Always treat the cables carefully and protect them from damages during transportation.
Install the cables always in a structured way and protect them from damage.
