RPS15 User Guide 7
Operating the RPS15
The RPS15 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, +8V, +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.
Cleaning the Unit
The RPS15 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.
Replacing the mains fuse
The AC mains fuse is located on the rear of the RPS15 unit next to the AC mains connector. In the event of a
mains surge or under-rated fuse value, the fuse will rupture. Switch off the power supply and remove the mains
lead plug from the “MAINS INPUT” socket on the rear of the unit. Check the fuse and replace if necessary. In the
event of repeated failure of the mains fuse, consult your Allen & Heath service agent.
In the unlikely event of an internal DC rail fuse failure, consult your Allen & Heath service agent or Allen & Heath
technical support.
TO AVOID THE RISK OF FIRE REPLACE FUSE WITH THE CORRECT TYPE ONLY, AS INDICATED
ON THE UNIT.
