Do not remove or tamper with the ground connection in the power cord.
WARNING: This equipment must be earthed.
Water and moisture:
To reduce the risk of fire or electric shock do not expose the power supply unit
to rain or moisture or use it in damp or wet conditions. Do not place
containers of liquid on it which might spill into any openings.
Ventilation:
Do not obstruct the ventilation slots or position the power supply unit where
the air flow required for ventilation is impeded. If the power supply unit is to
be operated in a flightcase ensure that it is constructed to allow adequate
ventilation.
Heat and vibration:
Do not locate the power supply unit in a place subject to excessive heat or
direct sunlight as this could be a fire hazard. Locate the power supply unit
away from any equipment which produces heat or causes excessive vibration.
Servicing:
Switch off the equipment and unplug the power cord immediately if it is
exposed to moisture, spilled liquid, objects fallen into the openings, the power
cord or plug become damaged, during lightening storms, or if smoke, odour or
noise is noticed. Refer servicing to qualified technical personnel only.

Precautions
4
Damage :
To prevent damage to the power supply unit cosmetics, avoid placing heavy
objects on the unit, scratching the surface with sharp objects, or subjecting the
power supply unit to rough handling and vibration.
Environment :
Protect from excessive dirt, dust, heat and vibration when operating and
storing. Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and
moisture. If the power supply unit becomes wet, switch off and remove power
immediately. Allow to dry out thoroughly before using again.
Cleaning :
Avoid the use of chemicals, abrasives or solvents. The power supply unit is
best cleaned with a soft brush and dry lint-free cloth. The use of electrical
lubricants is not recommended.
Transporting :
The power supply unit should be transported in the original packing or
purpose built flightcase to protect it from damage during transit.
DC power cable:
Plan the location of the mixing console and power supply unit so that the DC
power cable is not fully extended. Full extension of the cable can stress the
mixing console and power supply unit connectors and may result in undesired
performance. Ensure that the power cable is located such that it cannot be
stood on or tripped over.

The RPS15
The slimline RPS15 power supply unit is a high performance, low noise linear power supply producing DC
voltages by rectifying, smoothing and regulating AC voltages from the secondary windings of a mains transformer.
Allen & Heath mixing consoles employ a number of DC voltage supply levels in their operation and these are
provided at the output of the power supply unit. Full protection and thermal sensing fan cooling ensures the
power supply unit will operate consistently.

Installation
Free standing
The RPS15 can be operated as a freestanding unit for shelf or floor operation. Ensure adequate air flow around
the unit. It must not be covered in any way. Always stand the unit on a firm flat surface well away from any soft
furnishings or carpet.
Rack mounting
The RPS15 is designed as a 19 inch rack mount unit and will occupy 2U (3.5 inches) of rack space. The fast feet
may need to be removed before rack mounting. Retain feet for future use.
An important consideration when rack-mounting the unit is the need for natural convection of airflow around the
unit. Good ventilation below the unit, in the floor or back of the rack, will ensure a continuous path for airflow.
Rack equipment known to produce a significant amount of heat should not be mounted directly below the power
supply unit. Equipment which also relies on good airflow within the rack (i.e. most power amplifiers and other
power supply units) should be given due consideration and some space should be provided between such units
and between the RPS15 unit. Forced convection, by means of a fan-tray, may be desirable in some situations.
Location
As with any power supply unit that contains a mains voltage transformer, it is preferable to provide a degree of
physical isolation of the unit from other equipment, particularly that which carries low level audio signals, to avoid
any possible interference pick-up. For this reason power supply units supplied with Allen & Heath GS series
mixing consoles are provided with a long (2.9m) output cable to enable them to be positioned away from the
mixing console. For the same reason, when rack-mounting it is preferable to avoid locating the unit next to signal
processing equipment.
Earthing
Finally, some consideration should be given to the earthing arrangement of the system, at the centre of which is
the console and the RPS15. The console chassis is earthed to the mains earth via the power supply unit. When
rack-mounting the RPS15 care should be taken to avoid any possible “ground loops” in the system which may
introduce audible hum or buzz to otherwise clean audio signals. Ground loops occur where signal processing
equipment patched to the console, has its signal earth connected to the equipment chassis. A ground loop is
formed if the chassis of the signal processing equipment and the RPS15 chassis are in electrical contact through
the fixing rails they share in the rack. The RPS15 has audio 0V and mains earth connected internally.
Fitting in a rack
The RPS15 is supplied ready for use free standing.
For rack mounting remove and retain the four rubber
feet.

RPS15 User Guide
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.
