Hints on installation

DO NOT run microphone cables near mains, data, telephone or 70V line cables.
DO NOT run 100 V line cable near data, telephone or other low voltage cables.
DO NOT exceed 90% of the amplifiers output power when using 70V line (speech
or high level background music).
DO NOT use re-entrant horn loudspeakers for background music unless the
Loudspeaker has been specifically designed for this purpose.
AVOID jointing the microphone cable, when this is unavoidable make sure a good
screened connector is used.
ALWAYS use a unbalanced or floating low impedance microphone terminating into
a unbalanced input on long microphone cable lines.
ALWAYS use a mains grade double insulated cable for the loudspeaker cable runs.
ENSURE that all loudspeakers are in-phase.
ENSURE that there are no short circuits on the loudspeaker lines connecting to the
amplifier.
