Arcam Alpha 8P - Manual (Page 7)

ENGLISH
0 POWER - Switches the power on and off.
0 POWER LED - This will initially glow amber. After a
few seconds, it will glow green. When the LED glows
amber, the speakers are disconnected and an internal
protection circuit is activated.
■ If this LED glows amber during normal use it may be
due to the amplifier overheating or an output overload.
Check the amplifier is properly ventilated. Switch the
amplifier off and wait for 2-3 minutes before switching
on again.
If the LED continues to glow amber, switch the unit off,
remove all the speaker cables and switch on again. If
the LED goes to green on switch on then check the
speaker and speaker cables for short circuits before
reconnecting them. If the LED continues to glow
amber with no speakers connected contact your
Arcam dealer.

BI-WIRING/BI-AMPING INSTRUCTIONS
Many modern loudspeakers are equipped with four
connection terminals. This provides direct access to the
high frequency and low frequency filter networks and
associated drive units within the loudspeaker.
Overall performance can be enhanced by making use of
these separate connections.
WARNING: Do not make any connections to your amplifier
while it is switched on and connected to the mains supply.
Please check all connections thoroughly before attempting
to re-connect the mains power supply. Always ensure that
the volume control on your amplifier is set to a minimum
before switching on.
BI-WIRING
Bi-wiring uses four conductors, one for each terminal, to
enhance
dramatically the performance of your
loudspeakers. Bi-wiring eliminates the signal distortion
arising from the low and high frequency currents interacting
with one another within a single cable, as used in
conventionally wired systems.
HOW TO BI-WIRE YOUR LOUDSPEAKERS
1. Remove the shorting links from each of the red and
black terminal pairs on the rear of your loudspeakers.
2. You will need two lengths of loudspeaker cable per
loudspeaker (which may be joined at the amplifier end)
or a suitably terminated cable set capable of being
used for bi-wiring in one length.
3. Connect the cables as per one of the diagrams
opposite, dependant on your cable wiring, ensuring
correct polarity at all times. The positive (+)
connections on the right loudspeaker must go to the
positive (+) connections on the right channel of the
amplifier and the negative (-) connections on the right
loudspeaker must go to the negative (-) connections
on the right channel of the amplifier etc.
