User’s Manual
INSTALLATION: ELECTRICAL
The amplifier has been manufactured to
comply with your local power supply requirements,
but before connecting the unit to the supply,
ensure that the voltage (printed on the rear panel)
is correct, and that a mains fuse of the correct
type and rating has been fitted.
Make sure power outlets conform to the power
requirements listed on the back of the unit.
Damage caused by connecting to improper AC
voltage is not covered by the warranty.
SAFETY WARNING
Apparatus with CLASS I construction shall be
connected to a MAINS socket outlet with a
protective earthing connection.
Where a MAINS plug or appliance coupler is
used as the disconnect device, it should remain
readily operable.
Where the amplifier is mounted in a rack and
permanently connected to the mains, then the
rack should be installed with a readily accessible
connector or an ALL POLE circuit breaker with
3mm breaking distances.
This unit is fitted with a 3-wire power
connector. For safety reasons, THE EARTH LEAD
SHOULD NOT BE DISCONNECTED IN ANY
CIRCUMSTANCE.
If
ground
loops
are
encountered consult the section on input
connections later in this manual.
WHERE A FIXED MAINS LEAD IS FITTED,
THE WIRING COLOURS ARE:
230V AREAS:
EARTH = GREEN AND YELLOW
NEUTRAL = BLUE
LIVE = BROWN
120V AREAS:
EARTH = GREEN
NEUTRAL = WHITE
LIVE = BLACK
TO PREVENT THE LIKELIHOOD OF SHOCK
OR FIRE HAZARD, DO NOT EXPOSE THE UNIT
TO RAIN OR MOISTURE. DO NOT PLACE
OBJECTS CONTAINING LIQUID ON TOP OF THE
APPARATUS.
TO AVOID ELECTRICAL SHOCK DO NOT
REMOVE COVERS. REFER ALL SERVICING TO
QUALIFIED PERSONNEL.
DO NOT USE THE UNIT OF THE ELECTRICAL
POWER CORD IS FRAYED OR BROKEN. The
power supply cords should be routed so that they
are not likely to be walked on or pinched by items
placed upon or against them, paying particular
attention to cords and plugs and the point where
they exit from the appliance.
ALWAYS OPERATE THE UNIT WITH THE AC
GROUND
WIRE
CONNECTED
TO
THE
ELECTRICAL SYSTEM GROUND. Precautions
should be taken so that the means of grounding of
a piece of equipment is not defeated.
DO NOT REMOVE THE LID. Removing the lid
will expose you to potentially dangerous voltages.
There are no user serviceable parts inside.
ESD strikes to the unit's front panel that are in
excess of 4000 volts may cause disturbance to
the status LEDs on the unit. This will not affect
audio performance and will be corrected on the
next power up cycle.
INSTALLATION: MECHANICAL
To ensure that this equipment performs to
specification, it should be mounted in a suitable
rack or enclosure as described below. Like all high
power amplifiers, it should be kept away from
other equipment which is sensitive to magnetic
fields. Also, this amplifier may suffer a substantial
reduction in performance if it is subjected to, or
mounted close to equipment which radiates high
RF fields.
Warning: To prevent injury, this apparatus must
be securely attached to the rack in accordance
with the installation instructions.
When mounting the amplifier in a rack or
enclosure:
Be aware that ...
THE FRONT PANEL IS NOT CAPABLE OF
SUPPORTING THE UNIT ON ITS OWN.
Make sure that the rear of the unit is adequately
supported. The brackets which are supplied fit
standard 19 inch (483mm) rack mounting
systems.
ENSURE THERE IS ADEQUATE VENTILATION.
The cooling fans suck cool air in through the front
and blow hot air out at the rear of the unit through
the ventilating grills. The front and rear of the
amplifier should have free exposure to the air (i.e.
in a rack leave the front & rear doors off), with 2cm
air gap at the sides.
IF AIR IS NOT ALLOWED TO ESCAPE FROM
THE REAR, OVER-HEATING WILL OCCUR.
Take care when mounting other equipment in the
same rack.
Make sure that the rack unit has a separate
earth connection (technical earth).
The high frequency resonant converters in the
D-100
amplifiers have been designed to have very
low radio frequency (RF) emissions; however even
these low level emissions can cause interference
with other equipment.
In order for this to be minimised, the amplifier
should be mounted in a metal rack enclosure,
which should have a separate (technical) Earth.
Alternatively a separate earth should be attached
to the amplifier at the rear rack mounting bracket.
