Inputs

A good cable run improves the sound quality remarkably. Input cables should be short and direct, since high
frequencies will be 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.
The inputs of your OMNITRONIC ZD-160 are equipped with XLR-sockets.

Outputs

The high damping factor of your equalizer 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.
The outputs of your OMNITRONIC ZD-160 are equipped with XLR-connectors.

Connection with the mains

Connect the device to the mains with the enclosed power supply cable.
The occupation of the connection-cables is as follows:
Cable Pin
Brown Live
Blue Neutral
Yellow/Green Earth
The earth has to be connected!
If the device will be directly connected with the local power supply network, a disconnection switch with a
minimum opening of 3 mm at every pole has to be included in the permanent electrical installation.
The device must only be connected with an electric installation carried out in compliance with the IEC-
standards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum
fault current of 30 mA.

OPERATION

Make sure to power-up before your power amplifier is turned in order to avoid loud transients which could
damage your speakers or annoy your audience.
Switch the device on via the power switch.

CLEANING AND MAINTENANCE

The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
