Introduction & Installation
INTRODUCTION
Arcam's Alpha series of amplifiers is designed to be the
finest sounding range of hi-fi amplifiers currently available in
its price category.
The latest Alpha 7 and 8 models feature improved output
circuit protection compared with their predecessors. They
may also be upgraded at any time with the addition of the
matching Alpha 8P or 9P power amplifiers.
The Alpha 7 amplifier is rated at 40 watts per channel into
8 ohms. The Alpha 8 and 8P are rated at 50 watts per
channel into 8 ohms. In addition the Alpha 8's volume
control is motorised, allowing it to be operated from a
suitable remote control handset such as those supplied with
ail Arcam CD players. Arcam's "Handi-Remote", model
CR30 is also suitable. This is available as an optional extra
from your Arcam dealer. For the above reasons no handset
is supplied with the Alpha 8 amplifier.
This manual is in four parts:

LOUDSPEAKER CONNECTIONS
■
Dependent on the market where the amplifier is
intended for sale it may be fitted with either "Camcon"
loudspeaker connectors, which are designed to meet
EU safety standards, or with 4mm loudspeaker
sockets.
In Europe the 4mm holes will have been blanked off in
order to comply with European product safety
regulations. These sockets will still accept bare wire or
pin terminations.
The "Camcon" connector will accept spade terminals,
bare wires up to 4mm in diameter or a "Camcon"
plug. "Camcon" plugs are available from your arcam
dealer.
/
■
Connect your loudspeakers so that the red (positive;
terminal on each loudspeaker is connected to the
appropriate red terminal on the amplifier.
Your
loudspeaker cables may be clearly terminated to show
polarity; if not, then the positive conductor can usually
be identified by a ridge or coloured marking.
Ensure that no stray strands are allowed to touch
another cable or the amplifier's casing. This can
cause a short circuit and damage your amplifier!
