5 Setup

Installation

The equalizer can be used as a tabletop unit or installed in a 19" (483 mm) rack using the mounting brackets
provided. For rack installation, screw on the brackets at the left and right side of the housing; then fix the unit
with four M6 screws in the rack. A height of 1 unit is required. 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.

Cable connections

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. 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. Be sure to use only high-grade cables. The
illustrations below show the wiring of these cables.
