Operating the RPS14
The RPS14 is internally wired to operate from one of the following standard settings: 100V, 120V, 220V, or 240V.
The unit is shipped pre-wired for the country in which it is to be used.
Check that the rear panel is marked to indicate the voltage that is correct for your territory. The
power supply unit is provided with an IEC type mains connector and moulded mains plug. Check that
this is correct for connection to your wall socket outlet.
Switch the unit on by setting the front panel POWER ON switch to its ON position. The three front panel voltage
rail indicators (+/-17V, +12V, +48V) should light. The ‘HI TEMP’ indicator should be off during normal operation.
It lights to warn when the power supply unit is becoming too hot. Should that be the case, improve the ventilation
or lower the air temperatures around the unit.
To avoid audible thumps and bangs through the speakers, always turn the console on before
switching on the amplifier system, and turn the amplifiers off before switching off the console power
supply unit.
Always switch the power supply unit off before connecting or disconnecting the console power cables, removing
or installing console modules and any servicing work. In the event of an electrical storm, or large mains voltage
fluctuations, immediately switch off the power supply unit and disconnect from the mains supply.
Combining Power supply units
The RPS14 has a built-in combiner allowing direct connection to another
power supply unit for backup. It can be combined with either another
RPS14 or the alternative MPS14 power supply unit. Either can be used
as the main or backup supply.
Connect the two power supply units together using the DC link cable
provided by plugging into the DC sockets of each unit as shown below.
Note that the DC link cable can be connected to either of the two DC
output connectors on both units.
Avoid fully extending the DC cables when plugging in as this
may stress the cable and connectors resulting in failure.
Ensure that walkways, aisles and gangways are not obstructed by cables.
To ensure correct performance we recommend that you do not extend or
modify the DC power cable in any way.
Cleaning the Unit
The RPS14 does not use any internal filters. Air is drawn through the fan grille on the rear, blown through a
heatsink tunnel and out through ventilation slots in the front panel. It is not necessary to open the unit for
cleaning. Simply keep the fan and ventilation slots free of dust and dirt using a vacuum cleaner and dry, lint free
cloth. Do not use liquid cleaners or compressed air to clean the unit.
Always switch the unit off when inspecting or cleaning it.
