Arcam Alpha 10/10P - Manual (Page 8)

ENGLISH
The connecting cable required is a 3.5mm to 3.5mm jack lead
(stereo or mono) and it is possible to connect several 10P
power amplifiers to an integrated Alpha 10 by "daisy chaining"
from “control out” of one into the” remote in” of the next one,
etc.
For connection details see instruction sheet included with third
channel option.
Please contact your dealer for availability of this module.
THIRD CHANNEL OPTION ®
This option enables you to have a 5 channel amplifier in two
cases, when used in addition with a suitable power amp such
as the Alpha 10P, for use in a high quality Home Cinema setup.
The third channel can then be used to drive the centre speaker.
BI-WIRING/BI-AMPING INSTRUCTIONS ENGLISH
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 (-i-) 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.
BI-AMPING
The performance of your system can be further enhanced over
that achieved with bi-wiring, by extending the same principal
one stage further to include separate amplification for the low
and high frequency speaker drive units as well as separate
loudspeaker cables. This is known as biamplifying, or bi-amping
for short.
To implement bi-amping therefore requires four amplification
channels. In practice this is done by using two stereo
amplifiers: when one of these is an integrated amplifier it is best
to use this drive the high frequency (HF) units whilst the
outboard power amplifier is used to drive the low frequency (LF)
units.
We recommend that you use identical amplifiers to avoid
potential imbalances in sonic performance and sensitivities.
The Alpha 10/1 OP combination is ideal. It is however possible
to mix the Alpha 10 and the Alpha 9 range of amplifiers.
