Installation and wiring
Carefully unpack the
MP 3000 HV
and store the original packing materials
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 be sure to 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 lacquer and the unit’s feet at a non-visible point.
The unit should be placed on a rigid, level base. When placing the unit on
resonance absorbers or de-coupling components make sure that they do not
compromise the stability of the unit.
The quality and characteristics of the base on which your high-quality Hi-Fi
equipment stands define the limits of sound quality which can be achieved. The
base surface should be as heavy, rigid, hard and level as possible.
The receiver should be set up in a dry, well-ventilated 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 inflammable.
When installing the unit 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 unit and could
be a source of danger. Be sure to leave at least 10 cm free space above the unit
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 unit.

Notes on connections:
•
Be sure to push all plugs firmly into their sockets. Loose connections can
cause hum and other unwanted 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 reversed.
•
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 lead in
conjunction with 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.
The screen on the
MP 3000 HV
should now light up, and the unit should
respond to the controls.
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
