The DNA Pro Amplifier system is designed to be mounted in a standard 19” rack enclosure.
Where the amplifier is used in a fixed installation, as long as the bottom unit is supported and there
are no gaps between units, it is acceptable to use only the front panel 19” rack holes when fitting it
in a standard rack enclosure. If the amplifier is mounted in a mobile rack it is important that the rear
is supported with a rear rack mounting kit (part number ZA1182). Damage caused by insufficient
support is not covered by the warranty.
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 DNA Pro 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.
AC Power Connection
The amplifier utilises a 32A Neutrik PowerCon
TM
type locking AC power connector. Use only an AC
power cord with a correctly terminated PowerCon
TM
type connector to make the connection to the
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 while the amplifier will operate correctly at voltages indicated, the specified output power
will only be achieved when operating with the stated nominal voltages.
