If the colours of the wires in the mains lead 
of this device may not correspond with the 
coloured markings identifying the terminals in 
your plug, proceed as follows:
If a 13 Amp (B.S.1363) plug or any other type 
of plug is used, a 5 Amp fuse must be fitted 
either into the plug or at the distribution

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 an unbalanced or floating low 
impedance microphone that terminates into 
an unbalanced input on long microphone 
cable runs.
ALWAYS use a balanced source with a low 
impedance microphone that terminates into 
a balanced input for long line level mic/line 
cable runs.
ALWAYS use a mains grade double insulated 
cable for loudspeaker cable runs. 
ENSURE that all loudspeakers are in-phase.
ENSURE that there are no short circuits on 
the loudspeaker line before connecting it to 
the amplifier.
