To prevent damage to the front panel it is recommended that plastic cups or washers are fitted
underneath the rack mounting bolt heads.
It is possible to mount multiple Di Series amplifiers without ventilation gaps between them but it is
essential that an unobstructed flow of clean air is available from the front of the unit to the rear. It is
important that neither the air intakes on the front of the unit or the exhaust vents at the rear are
covered. Steps must be taken to ensure that hot air does not continually circulate through the
amplifiers from the back of the rack to the front.
The amplifier should never be exposed to rain or moisture during operation or storage. If the unit does
come into contact with moisture, remove the AC power cord immediately and leave it in a dry and
warm location to dry out.
Note that when any equipment is taken from a cold location into a hot humid one, condensation may
occur inside the device. Always allow time for the equipment to attain the same temperature as its
surrounding environment before connecting the AC power cord.
IMPORTANT
It is the responsibility of the user to ensure that dirt, liquids and vapour from theatrical smoke and fog
machines is not ingested by the amplifier. Damage so caused is not covered by the manufacturer's
warranty.
AC Power Connection
The amplifier utilises a 32A Neutrik PowerCon
type locking AC power connector. Use only an AC
TM
power cord with a correctly terminated PowerCon
type connector to make the connection to the
TM
mains power supply.
The amplifiers are designed to operate on 50/60 Hz AC power. The power supply sections
automatically configure themselves for either 115V or 230V nominal voltage at turn on. The
amplifiers will operate over an extended range of supply voltages (please refer to the technical
specifications).
Note that whilst the amplifier will operate correctly at voltages indicated, the specified output power
will only be achieved when operating with the stated nominal voltages.
