INSTALLING THE POWER SUPPLY UNIT

Refer to the SAFETY WARNING on the first page of this User Guide.
The RPS9 Power supply is provided with the GL3300 to convert the AC mains voltage to the regulated
positive and negative DC voltages required to power the console. It also supplies the +48V DC phantom
power voltage for use with certain microphones. It connects to the console by means of a 2.5 metre DC
power cable fitted with a locking 5 pin XLR plug. Mains input to the RPS9 is via a mains cable with
moulded plug suitable for the local supply. A standard 3 pin IEC connector plugs into the RPS9 mains in
socket with integral voltage selector and AC mains fuse.
The RPS9 may be operated free standing or 19" rack mounted (2U height) up to 2 metres away from the
console. As with any power supply unit it is recommended that it is positioned away from the console or
other signal processing equipment containing sensitive low level audio signals to avoid any possible hum
pickup.
AC mains supply = 100 to 110 V.AC
AC mains supply = 110 to 125 V.AC
AC mains supply = 210 to 230 V.AC
AC mains supply = 235 to 260 V.AC
Note: The RPS9 is fitted with a rear panel ground lift switch. This is for use when the unit powers certain
other Allen & Heath equipment. This switch is not operative on the GL3300 range. Refer to the section
on 'EARTHING THE AUDIO SYSTEM'.

To avoid the risk of fire replace the fuse only with the correct
type and value as specified on the unit.
It is normal for the power unit to dissipate heat. Ensure adequate
ventilation around the unit. 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.
Always switch the power unit off before connecting or
disconnecting the console power cable.
This unit contains no user serviceable parts. Do not remove the
