Installation and wiring
Carefully unpack the amplifier and store the original
packing material carefully. The carton and packing are
specially designed for this unit and will be needed again if
you wish to move the equipment at any time.
Please read the safety notes in these instructions.
If the unit gets very cold (e. g. when being transported),
condensation may form inside it. Please do not switch it
on until it has had plenty of time to warm up to room
temperature, so that any condensation evaporates
completely.
Before placing the unit on a sensitive surface please
check the compatibility of the laquer and the unit's feet on
a non visible point.
The unit should be placed on a rigid, level base. When
placing the unit on resonance absorbers or anti-resonant
components make sure that the stability of the unit is not
reduced.
The amplifier should be set up in a well ventilated dry site,
out of direct sunlight and away from radiators.
The unit must not be located close to heat-producing
objects or devices, or anything which is heat-sensitive or
highly flammable.
When installing the amplifier on a shelf or in a cupboard it
is essential to provide an adequate flow of cooling air, to
ensure that the heat produced by the unit is dissipated
effectively. Any heat build-up will shorten the life of the
amplifier and could be a source of danger. Be sure to
leave at least 10 cm free space above the amplifier for
ventilation. If the system components are to be stacked
then the amplifier must be the top unit. Do not place any
object on the top cover.
Mains and loudspeaker cables, and also remote control
leads must be kept as far away as possible from signal
leads and antenna cables. Never run them over or under
the amplifier.
The wiring diagram shows a typical wiring arrangement for
the amplifier integrated amplifier within a
'R' system.
Notes on connections:
• Be sure to push all plugs firmly into their sockets.
Loose connections can cause hum and other un-
wanted noises.
•
When you connect the input sockets of the amplifier to
the output sockets on the source devices always
connect like to like, i. e.
'R' to 'R' and 'L' to 'L' . If you
fail to heed this then the stereo channels will be rever-
sed.
•
When connecting a recorder be sure to connect the IN
sockets of the recorder to the OUT sockets of the
amplifier, and the OUT sockets of the recorder to the
IN sockets of the amplifier.
•
If the remote control module is installed connect the
plug on the E 2000 remote control receiver to the
socket marked RC-IN E 2000 . The R
LINK
socket of
the amplifier should be connected to the R
LINK
socket
of the source devices (see ' Wiring diagrams ' ).
•
The amplifier integrated amplifier is designed to be
used with an 230 V AC (alternating current) mains
supply. Connect it to a correctly earthed mains socket
using the mains lead supplied.
• The amplifier can also be used in Bi-Wiring or
Bi-Amping mode. These wiring variants are shown in a
separate wiring diagram.
•
To achieve maximum possible interference rejection
the mains plug should be connected to the mains
socket in such a way that phase is connected to the
mains socket contact marked with a dot (
). The
phase of the mains socket can be determined using
a special meter. If you are not sure about this, please
ask your specialist dealer.
We recommend the use of the  'POWER LINE'
ready-to-use mains cable and the 'POWER BAR' mains
distribution panel which is fitted with a phase indicator as
standard.
When you have completed the wiring of the system
please set the volume control to a very low level before
switching the system on.
Switch on the loudspeaker outlet to which your speakers
are connected and switch the integrated amplifier to the
listening source which you wish to hear. You should now
hear the music.
If you encounter problems when setting up and using the
amplifier for the first time please remember that the
cause is often simple, and equally simple to eliminate.
Please refer to the section of these instructions entitled
' Trouble shooting ' .
