18 GL4800 User Guide
Connecting Power
Connect only the Allen & Heath power unit specified for the console. The standard unit for
GL4800 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 via the backup DC power connector
(located adjacent to the main DC power connector at the rear of the console).
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.
Before Switching On !
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.
