5. SETTING INTO OPERATION

5.1 Rack installation

Install the unit on a plane surface or in your rack. For 19" (483 mm) rack installation, 1 unit is required. When
mounting the unit into the rack, please make sure that there is enough space around the device so that the
heated air can be passed on. Steady overheating will damage your device. You can fix the unit with four
screws M6 in the rack.

5.2 Connecting audio devices

Disconnect the equalizer from the mains and switch off the units to be connected before making or changing
the connections.
1. The equalizer can be inserted as required, e. g. between preamplifier and power amplifier, between
mixer and power amplifier or into an effect way of a mixer.
2. The inputs and outputs can be connected both balanced via XLR plugs and unbalanced via RCA plugs.
Balanced cables provide +6 dB more output and guarantee a better protection against interference in
case of long cable runs.
• Connect the signal source to the input jacks INPUT.
• Connect the PA amplifier or the subsequent unit to the output jacks OUTPUT.
The XLR output jacks are equipped with a lock which is released by pressing the PUSH lever down and
pulling the plug out at the same time.
