INSTALLING THE POWER SUPPLY UNIT

Refer to the 

SAFETY WARNING

 

on the first page of this User Guide.

Power supply type 

RPS9

 is provided with the 

GL3000

 to convert AC mains voltage to the regulated

positive and negative DC voltages required to power the console.  It also supplies the +48V phantom power
voltage for use with certain microphones.

 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 slightly away from the console
or other signal processing equipment containing sensitive low level audio signals to avoid any possible hum
pickup.  It connects to the console by means of a 2.5 metre DC power cable fitted with a 5 pin locking XLR
plug.  Mains input to the 

RPS9

 is via a standard 3 pin IEC mains connector with integral AC mains fuse.

A mains cable with moulded plug suitable for the local supply is provided.

The 

RPS9

 power supply unit conforms to safety standard

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 

GL3000

 range.  Refer to the section

on 'EARTHING THE AUDIO SYSTEM'.
