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 dealer or Arcam,

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 diagrams, 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.
