General Installation
DO NOT run unbalanced high impedance
microphone cables near mains, data,
telephone or 70/100V line cables.
DO NOT run 70/100V line cable near data,
telephone or other low voltage cables.
DO NOT exceed 90% of the amplifiers output
power when using 70/100V line (speech only).
DO NOT exceed 70% of the amplifiers output
power when using 70/100V line (high level
background music).
DO NOT use voice paging 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 balanced low impedance
microphone cable terminating to balanced
inputs on long cable runs.
ALWAYS use a mains grade double insulated
cable for the loudspeaker cable runs when
run in conduit together with power cables.
ENSURE that all loudspeakers are in-phase.
ENSURE that there are no short circuits on
the loudspeaker line before connecting to the
amplifier. It is also advisable to check the final
impedance to the amplifier with a dedicated
impedance meter to determine power draw is
within the amplifiers limits.
IMPORTANT
The wires in the mains lead are coloured In
accordance with the following code:
Green and Yellow: Earth (E)
Blue: Neutral (N)
Brown: Live (L)
As the colours of the wires in the mains lead
of this apparatus may not correspond with the
coloured markings identifying the terminals in
your plug proceed as follows:
The wire which is coloured green and yellow
must be connected to the terminal which is
marked with the letter N or coloured black.
The wire which is marked with the letter L or
coloured red.
If a 13 Amp (B.S.1363) plug or any other type
of plug is used, a 5 Amp fuse must be fitted
either in the plug or at the distribution board.
