Introduction & Installation
ENGLISH
INTRODUCTION NOTES ON USE
This manual is in four sections;
A. Information relevant to both the Alpha 10 and Alpha
10P.
B. Alpha 10 integrated amplifier operating instructions.
C. Alpha 10P power amplifier operating instructions.
D. Instructions on how to bi-wire or to bi-amplify (“bi-amp”)
your loudspeakers.
Circindicator numbers e.g. refer to items on the
diagrams inside the flap of the front cover.
Section A
INSTALLATION
O
Check that your mains supply voltage agrees with the
voltage setting indicated on the rear panel of the unit.
■ If your mains supply voltage is different, consult your
Arcam dealer.
MAINS SAFETY
■ This product is normally supplied with a moulded mains
plug already fitted to the lead. If for any reason the plug
needs to be removed, it must be disposed of
immediately and securely, as it is a potential shock
hazard when inserted into a mains socket.
■ Warning: This apparatus must be earthed.
NOTICE FOR U.K. OWNERS ONLY
■ If the plug is removed then the remaining lead must be
rewired as follows:
■ The blue wire must be connected to the terminal which
is coloured blue or marked with the letter N.
■ The brown wire must be connected to the terminal
which is coloured brown or marked with the letter L.
i The green and yellow wire must be connected to the
terminal which is coloured green and yellow, or marked
with the letter E or the safety earth symbol.
■ When replacing the fuse in the supplied moulded mains
plug, the integral fuse holder/cover must always be
refitted. Use a 5 amp fuse.
SAFETY STANDARD
The Alpha 10 and 10P amplifiers will play music within seconds
of being switched on. However the optimum sound
reproduction will be achieved after the units have been
powered up for a few minutes.
Note: On switch on there may be an audible hum from the
transformers within the units. This is normal and should
disappear within a few seconds.
CAUTION: Your Alpha 10 and Alpha 10P generate heat when
in use, particularly at higher volumes. It is therefore most
important never to obstruct the ventilation slots on the top and
bottom of the unit as this will cause overheating.
If the temperature of the internal heatsinks rises above a safe
level, then a thermal cut out inside the amplifier will operate.
The POWER INDICATOR on the front panel will turn amber
and the output protection relays will temporarily remove the
feed to the loudspeakers. The system will reset itself as the
heatsinks cool down.
Please note that under certain conditions it may be possible for
the Alpha 10 or Alpha lOP's thermal cut out to operate when
playing music at very high levels.
This might for example happen when continuously playing
heavily compressed rock music "flat out" into low impedance
(4-6 ohm) speakers. If this happens to you, the cure is to turn
the volume down slightly and ensure the amplifier is properly
ventilated.
It is important to point out that when playing a heavily recorded
CD it is possible to drive the Alpha 10 at full power despite the
fact that the volume is not at maximum. This is because of the
high output voltage from a CD player. However the Alpha 10
also has to be capable of giving full power output from much
lower level sources, such as tuners and cassette decks. Using
these sources, the volume setting will be much higher before
overload sets in.
Section B
ALPHA 10 INTEGRATED AMPLIFIER
Please refer to drawing inside front cover.
LOUDSPEAKER CONNECTIONS
■ The amplifier is fitted with BFA (British Federation of
Audio) loudspeaker connectors, which are designed to
meet EU safety standards.
The BFA connector will accept spade terminals, bare
wires or a BFA plug. BFA plugs are available from your
Arcam dealer.
■ This product has been designed to meet the I EC 65
international electrical safety standard.
MAINS SUPPLY CONNECTIONS
Insert the lEC line socket of the mains lead fully into the O0
power inlet on the rear panel. Connect the other end to
your mains supply.
The speaker terminals are colour coded red for positive
and black for negative. These terminals are also
labelled 'R' for the right channel speakers and 'L' for the
left channel speakers.
Connect terminals © to your right speaker and
terminals 0 to your left speaker, ensuring correct
polarity.
