1. Installing Your Amplifier

1.1 Electrical Considerations

• 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. Damage
caused by connecting to improper AC voltage is not covered by the
warranty.
SAFETY WARNING
• 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 3 mm breaking distances.
• This unit is fitted with a 3-wire power cord. FOR SAFETY REASONS,
THE EARTH LEAD SHOULD NOT BE DISCONNECTED IN ANY
CIRCUMSTANCE. If ground loops are encountered consult the section
on connecting your amplifier on page Error! Bookmark not defined.
The wiring colours are:
220-240 V AREAS:
EARTH = GREEN AND YELLOW
NEUTRAL = BLUE
LIVE = BROWN
120 V AREAS:
EARTH = GREEN
NEUTRAL = WHITE
LIVE = BLACK

• DO NOT USE THE UNIT IF 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.

1.2 Mechanical Considerations

• 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
(483 mm) 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 2 cm 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).
• Please also see the notes regarding maintenance on chapter 4.1.
