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
