2. SAFETY PRECAUTIONS
2.2 POSITIONING
1. Location
OCTAVE equipment is designed strictly for
use in a
dry domestic environment
and
should never be used in the open air or in
damp rooms.
Never place plants or liquid filled objects
such as bottles or glasses on your OC-
TAVE equipment. Take care that objects do
not fall or liquids are not spilled into the
enclosure. Should this happen, remove the
mains plug immediately and have your
amplifier checked by a qualified service
technician.
Condensation may form if the equipment is
taken from a warm environment into a cold
one. In this case, wait until the room has
warmed up before switching the amplifier
on.
Avoid installing the unit close to sources of
heat
such as radiators or anywhere that it
may be in direct sunlight. Do not operate
the unit near flammable materials, gases or
vapours. Avoid areas where there may be
heavy accumulations of dust or where the
unit may be subject to mechanical vibration.
2. Level, stable base
Place your OCTAVE amplifier on a stable,
even surface. Special hi-fi equipment sup-
ports can be beneficial.
3. Good ventilation
Make sure that your amplifier has a
good
flow of air around it.
If you intend to install
your equipment in a cupboard or a shelf,
ensure that there is at least a two centimetre
gap between the ventilation slots and the
bottom of the shelf and a 20 centimetre gap
between each of the walls. The rear panel of
cupboards should have ventilation holes to
prevent heat build up. The equipment should
not be placed on a soft surface such as car-
pet or foam sheeting.
4. Hum
Encapsulated transformers reduce the affect
of magnetic interference on cables and other
hi-fi components such as CD players or
tuners. Nevertheless,
you should not place
any other electronic components directly on
or below your OCTAVE equipment.
You should always keep sensitive input cir-
cuitry well away from amplifier power sup-
plies. The mains transformer is located on
the left hand side of most audio equipment.
The input circuitry on OCTAVE amplifiers is
located directly behind the inputs.
5. Power supply
Do not position the Jubilee's power supply
directly on or next to the preamplifier. You
should also avoid placing any equipment
containing sensitive input circuitry, such as a
phono preamp, close to the power supply
(see Section 4. Hum)
