FAULTS AND THEIR LIKELY CAUSES

1.

INSTALLATION

UNPACKING
Although the power amplifier is a rugged piece of professional audio equipment and is

heavy, it is also a high specification modern electronic assembly and should be handled
with care.

The packaging of the unit is specifically designed to safely transport this product. In the
unlikely event of the product requiring servicing, this packaging is the safest way to
transport it.

All units are factory set for 230v operation.
Units factory made for 110/120V supply are clearly marked on the back and should not be
connected to any higher voltage power source.

SITING THE POWER AMPLIFIER

This power amplifier has been designed for rack mounting use, in a Racking enclosure
made to BS5954, IEC297 or Din 41494 standards.

a. The unit must be mounted in the horizontal position with clear cool air flow of 10cm
around each air vent. DO NOT STAND OR USE RACKS NEAR HEATING DUCT

OUTLETS, APPLIANCES OR RADIATORS.
If the rack is placed in an enclosed area (cupboard etc.) make sure that there

is plenty of rear ventilation and the air is not recycling.
b. Rack mounting - Ears are provided for both front and rear support; a choice of

mounting position is given on the front brackets ( either proud & level with the front
panel or sunk by 20mm and flush with the front escutcheon.)

c. Care is required when installing these units in a rack. It is advised to put the Rack
on its back, then place all the equipment being fitted into it before fitting retaining
bolts to avoid unnecessary handling damage. Rear support brackets are strongly
recommended to be used on each unit, to avoid transit damage.

FITTING A POWER LEAD & PLUG

The wires in the IEC/CEE mains lead are coloured:
Earth: Green/Yellow Neutral: Blue Live: Brown

As these colours may not correspond with the colour markings identifying the terminal in
your plug proceed as follows: Green/Yellow wire must be connected to the terminal which
is marked with the letter E or coloured Green. - Brown wire must be connected to the
terminal which is marked with the letter L or coloured red. - Blue wire must be connected
to the terminal which is marked with the letter N or coloured black.
