Installation
5.1
Mounting
IPX Series amplifiers are designed for installation in a conventional 19-inch rack case. Attach
the power amp with its frontal rack mount ears using four 20 mm screws and washers. If the
rack will be transported secure the amplifier at the rear. Failure to do so may result in damage
to the power amplifier as well as to the rack case. Attach the power amp using four case nuts
and screws. Brackets for securing the power amplifier in the rear are available as accessories
(RMK-15).

Mains power connection
Mains power connection (all countries except the USA)
The power amplifier receives its power supply via the MAINS connector. It is recommended to
use either the listed power cords or power distributions. Custom power cords using the
supplied connector have to be built from qualified personal following the safety and assembly
instructions. During installation, always separate the power amplifier from the mains. Connect
the power amplifier only to a mains network, which corresponds to the requirements
indicated on the type plate.
Mains power connection (USA only)
The power amplifier receives its power supply via the MAINS connector. Only the listed power
cords or power distributions shall be used. During installation, always separate the power
amplifier from the mains. Connect the power amplifier only to a mains network, which

Power

powers on the amplifier. Press the switch to the other side powers the
amplifier down. A soft start circuit compensates mains inrush current peaks and thus prevents
triggering AC mains fuse when switching on the amplifier.
Speaker system switch-on is delayed by approximately 15 seconds, while the amplifier is
booting—indicated by the green power LED flashing. During that time the speakers are
decoupled by relays. Reactivating the amplifier from Standby will take only a few seconds.
5.4
Ventilation
As with all Dynacord fan cooled power amps, the airflow direction is front-to-rear. When
installing the power amp in a case or rack system, attention should be paid to provide
sufficient ventilation. Allow for an air duct of at least 60 mm x 330 mm between the rear panel
of the power amplifier and the inner wall of the cabinet/rack case. Ensure the duct reaches up
to the cabinets or the rack case’s top ventilation louvers. Leave room of at least 100 mm
above the cabinet/rack case for ventilation. Temperatures inside of the cabinet/rack case can
easily rise up to 40 °C (104 °F) during operation of the power amp, it is mandatory to bear in
mind the maximum allowable ambient temperature for all other appliances installed in the
same cabinet/rack case.
