Connect only the Allen & Heath power unit specified for the console. The standard unit for GL4000
is the RPS11. This is an external 3U 19" rack mounted unit that connects to the console via the
separate DC cable supplied. The RPS11 is a low noise linear design that converts AC mains voltage
to the DC voltages required to power the console. It also provides +48V phantom power for use with
high quality powered microphones. The presence of AC mains voltage is shown on the power unit
front panel neon indicator. The presence of the DC voltages is shown on the console power indicator
LEDs. A second backup RPS11 may be connected to the console through the optional RPSD-2 dual
supply combiner unit available from your Allen & Heath agent if required.
SAFETY WARNINGS !
Ensure that the warnings printed on
the power unit (shown here) are
followed.
Always switch the power unit off before
connecting or disconnecting the
console power cable.
It is normal for the power unit to dissipate
heat. Do not cover the unit or position
it on soft furnishings during operation.
Do not position other equipment known
to generate significant amounts of heat
below the unit. It is recommended that
rack units containing high power
amplifiers and other heat dissipating
equipment are fitted with cooling fans.

!
Check that the voltage indicated on the
fuseholder is correct for the mains
voltage in your area.
Check that the mains IEC connector is
fully inserted into the inlet socket.
Check that the DC power cable is
correctly fitted to both the power unit
and the console. The locking ring
should be screwed in place.
It is recommended that audio power
amplifiers are switched on last and
switched off first to prevent possible
damage to loudspeakers.
Check the system for safety earthing.
