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.
