2. SAFETY PRECAUTIONS
2.1 BEFORE YOU BEGIN
Read the instructions before switching
the unit on.
Please read through this manual carefully
before switching on your amplifier and pay
particular attention to the safety instructions.
Please keep this manual safe for future ref-
erence and retain the original packing to use
whenever your amplifier is transported.
In case of emergency: disconnect the
plug from the mains supply
Never use an amplifier that is damaged or
faulty. Make sure that it cannot be used until
it has been repaired by a qualified service
engineer. You should also remove the mains
plug if you expect not to use the amplifier for
a long period.
Do not open the case
There are dangerously high voltages and hot
tubes inside this equipment. To avoid a burn
or the risk of electric shock, never allow
anyone except qualified personnel to open
the case.
Servicing and maintenance
To avoid the risk of any other hazards, ser-
vicing, repairs and other modifications to this
OCTAVE equipment should only be carried
out by qualified personnel. Always replace
fuses with ones of the same type and rating.
If your amplifier requires servicing, please
ship or take your equipment directly to OC-
TAVE or to one of our authorized service
centres.
Explanation of the symbols
The lightning flash with arrowhead symbol
within an equilateral triangle is intended to
alert the user to the presence of uninsulated
'dangerous voltages' within the product's
enclosure that may be sufficient to constitute
a risk of electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to im-
portant operating and maintenance instruc-
tions.
The CE mark certifies that this electrical
equipment complies with current European
Union product safety regulations such as
the Low Voltage Directive and the Electro-

Before connecting up
The Jubilee preamplifier is designed to
operate exclusively with the power supply
supplied. Make sure before connecting the
power cord that your amplifier is suitable
for your local supply voltage.
Protection class
In Japan this amplifier is a protection class
2, no earth connector. In other countries it
is a protection class 1 device (with protec-
tive earth conductor).
Adjusting the volume
While you are setting your amplifier up,
turn the volume control anticlockwise, close
to the minimum setting. High sound pres-
sure levels can damage to your hearing as
well as your loudspeakers.
Safety warning: Hot tubes
Tube equipment gets very hot and takes
about 20 minutes to cool down after you
have switched it off. The exterior of the
case, which can also heat up during normal
operation, and the protective grill fitted over
the external tubes are designed to protect
children and others from being burned
should they ever touch the hot tubes.
Warning: Remove the protective grill at
your own risk. OCTAVE accepts no re-
sponsibility for injuries caused by the re-
moval of this grill.
Warranty
OCTAVE can only guarantee the safety,
reliability and performance of this unit if
modifications and repairs are carried out by
specialized personnel and if the amplifier is
operated in accordance with the instruc-
tions contained in this manual.
