INSTALLATION

1.2.1

Basic System Installation

Installation of the KAB series public address amplifier must be performed by qualified service personnel
in accordance with all local and national electrical and mechanical codes.
Remove all components from the package and identify the items that will be used during installation.
A. Mount the amplifier into a suitable rack and secure it using all four rack mounting screws.
B. Check the voltage marked on the rear panel of the unit to ensure that it matches the supply
voltage. Connect the amplifier to the power source using the cable supplied. Do not defeat the
third ground pin of this unit; doing so may place the user at risk of electric shock.
C. Connect the audio input signal to the proper channels. MIC signals connect to XLR, while line-
level signals connect to the ¼" connectors. To keep noise minimized, always use a balanced cable
for the input connection.
D. Connect the speaker(s) to the proper Output screw terminals. The "hot" wire should connect to the
screw terminal marked with an impedance which matches the impedance of the load, and the
"cold" wire connects to the "COM" screw terminal.
