GENERAL INSTALLATION
DO NOT run microphone cables near mains, data, telephone or 70V line cables.
DO NOT run 100V line cable near data, telephone or other low voltage cables.
DO NOT exceed 90% of the amplifiers output power when using 70V line (speech
only).
DO NOT exceed 70% of the amplifiers output power when using 70V line (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, e.g. Phono.
ALWAYS use a unbalanced or floating low impedance microphone terminating into a
unbalanced input on long microphone cable runs.
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 line before connecting to
the amplifier.
