PLEASE READ THESE IMPORTANT
INSTRUCTIONS.

Safety Instructions

To reduce the risk of electric shock the user should not
remove the cover. All operating and safety instructions
should be followed. The unit should be kept clear of
water, fluids and moisture and not be operated in damp
conditions. The unit should be operated in a well
ventilated environment. The unit should be kept away
from excessive heat sources such as radiators and if
racked with other power amplifiers there should be a
free air flow to vent out the heat produced (check with
dealer). The unit must only be connected to a power
supply as shown on the rear of the unit with the IEC
cable (or similar) provided. The power cord must be
situated or routed so as not to be walked upon or
pinched or objects placed upon it with special attention
to the area where the power cable enters the IEC
socket at the unit. The power cable should be
disconnected during prolonged non usage. The user
should not attempt to service the unit or use the unit in
any way except as described in this manual. For
service and repair your dealer should be contacted.
This unit complies with relevant safety regulations.

POWER NOTICE FOR SAFETY

All British and European countries use a nominally
230v mains power supply. In practise this varies
between 220v and 240v. In the USA the nominal
supply is 115v and 100v in Japan. This unit is set to
the correct voltage in the factory and this can be
checked from the label on the rear panel. If you
intend to use this crossover in a country which has
a different mains supply voltage, you should
consult your dealer for advice. As there are no user
serviceable components inside the crossover, and
high voltages are present, DO NOT remove the
covers! Be sure to make all audio connections to
the crossover before connecting to the mains
supply.
