Arcam Alpha 8P - Manual (Page 6)

ENGLISH
© BALANCE - Rotate clockwise or anti-clockwise to
move the position of the stereo image. This may be
necessary if it is not possible to sit centrally between
the speakers. In normal use leave in the central 'click'
position.
© SP2 - Selects or defeats the loudspeakers connected
to the terminals marked SP2. The main pair SP1 are
permanently connected.
© HEADPHONES SOCKET - Accepts headphones
rated between 8 ohms and 2k ohms fitted with a
6.3mm stereo jack plug. If your headphones are fitted
with a different plug contact your dealer for a suitable
adaptor.
If you wish to listen on headphones only, connect
your speakers to the terminals marked SP2 and
release the SP2 switch to mute the speakers.
■ The headphone socket is always switched on,
irrespective of the position of switch ©.
© POWER - Switches the unit on and off.
© 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.
Section C
ALPHA 8P POWER AMPLIFIER
The Alpha 8P power amplifier can be used in conjunction
with an Alpha 7 or 8 integrated amplifier to bi-amplify
loudspeakers that offer two sets of input connections i.e. are
biwireable. The Alpha 8P can also be used with a
preamplifier or an AV processor or amplifier with power amp
out sockets.
MAINS CONNECTIONS
Connect up as per instructions for the Alpha 7 and 8
integrated amplifier.
LOUDSPEAKER CONNECTIONS
Connect up as per instructions for Alpha 7 and 8 integrated
amplifier.
CONNECTING TO YOUR SOURCE EQUIPMENT
© PWR AMP IN - Connect to your pre-amplifier outputs
or the PREAMP OUT sockets of a Delta 290 or Alpha
7, 8 or 9 amplifier.
® MONO LINK- The Alpha 8P can be connected to
provide two mono loudspeaker outputs from a single
input.
Using the U-link © supplied, connect the MONO
LINK sockets © together.
Utilising one Alpha 8P per loudspeaker in this manner
will allow bi-amplifying of biwireable loudspeakers.
This is particularly beneficial for top quality stereo
installations with a separate pre-amplifier, or for the
left, centre and right channel loudspeakers in a five
speaker Dolby Pro Logic system. Contact your Arcam
dealer for more detailed information.
OPERATION BY REMOTE CONTROL (ALPHA 8 ONLY)
■ The Alpha 8 amplifier is not supplied with a remote
control handset but is remote ready. The volume up
and down functions can be operated by the remote
control handsets supplied with all Arcam CD players.
It may also be possible to operate this function if your
CD player remote control handset has volume
up/down buttons and uses the Philips RC-5 remote
control protocol.
■ The Alpha 8 amplifier can also be muted by use of the
‘MUTE’ button on the remote control handsets
supplied with the Alpha 7, 8 and 9 CD players. The
POWER LED will glow amber in this case to indicate
that the amplifier has been muted. Pressing the
‘MUTE’ button again, or either of the volume up/down
buttons on your remote handset will cancel the MUTE
function.
■ Daisy Chain - The Alpha 8P is capable of driving
further Alpha 8P amplifiers (or any other power
amplifier), to drive more speakers (eg. those in other
rooms or tri-amplified speakers etc). Connect the
extra power amplifier inputs to the MONO LINK
outputs © left to left, right to right.
