INSTALLING THE POWER SUPPLY UNIT

Refer to the SAFETY WARNING on the first page of this User Guide.

The RPS9 power supply unit conforms to safety standard EN 60065

AC mains supply = 100 to 110 V.AC 100 T 3.15A 20mm fuse

AC mains supply = 110 to 125 V.AC 120 T 3.15A 20mm fuse

AC mains supply = 210 to 230 V.AC 230 T 1A 20mm fuse

AC mains supply = 235 to 260 V.AC 240 T 1A 20mm fuse

Check that the voltage indicated in the fuseholder window is the

same as the mains supply in your area.

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

cover. Refer servicing to qualified service personnel only.

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'.

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.
