Rear Panel Connections

CHANNEL INPUT XLR input for mic or line level

signals. Pin 2 hot. Phantom power is fed to pins 2

and 3 through 6k8 series resistors when the front

panel +48V switch is pressed.

WARNING: Do not connect

unbalanced sources or cables to the XLR inputs

when phantom power is selected. To avoid loud

clicks always turn the channel off by pressing

the MUTE switch when switching +48V on or off

and when plugging or unplugging microphones.

INSERT TRS jack socket for combined insert send

and return. Tip = send, ring = return, sleeve =

ground. The insert is post-HPF and pre-EQ. Use

this to insert line level processors such as

compressors into the channel signal path. The

channel signal is interrupted when you plug into the

INSERT socket. With nothing plugged in the signal

is passed through switching contacts in the socket.

DIRECT OUT TRS jack providing the post-fade

channel signal as standard. You can reconfigure

the output as pre-fader or as post-fader with the

AUX 1 send control as a level trim by repositioning

internal jumper links. The output is 0dBu ground

compensated line level for connection to balanced

or unbalanced equipment.

ST1-4 IN. Each provides two balanced stereo

inputs on TRS jacks. These can be selected

independently or mixed together into the stereo

channel. They accept line level signals such as CD,

2-track players and effects processors.

MAIN OUTPUTS. Line level balanced XLR outputs

for the Auxes 1-8, Groups 1-4, Matrix 1-4, L, R and

C main mix. Pin 2 hot. These outputs can provide

up to +23dBu maximum and are suited to driving

line level equipment operating at nominal 0dBu or

+4dBu. The C output is available as the engineers

wedge monitor feed when the front panel mode

switch is selected.

Note: The GRP and AUX signals always remain on

their respective connectors regardless of the setting

of the front panel REVERSE switches.

OUTPUT INSERTS. Each of the L,R,C, Matrix 1-4

and 8 small fader paths has a pre master fader

insert point. These are TRS jack sockets for

combined insert send and return. Tip = send, ring =

return, sleeve = ground. Insert line level processors

such as compressors, limiters, delays and so on

into the output signal paths. The output signal is

interrupted when you plug into the INSERT socket.

With nothing plugged in the signal is passed

through switching contacts in the socket.

Note: Fader paths 1-4 may be Group or Aux

depending on the position of the front panel mode

switches. This lets you use inserts 1-4 for groups or

auxes according to your application.

DC POWER IN Two heavy duty 10-pin connectors

with locking rings connects to the console power

supply units, one for the main supply, the other for

redundant backup if available. Early models do not

provide the second DC socket. For these, use the

optional RPSD2 combiner unit to connect the

second supply. A chassis ground terminal post is

provided for situations requiring earth strapping

between equipment.

WARNING: Use only the DC power

cable type as provided with the console. Refer

to the power supply user guide.
