C ONNECTING TO C HANNEL I NSERTS
You do not need to plug anything into the channel insert socket for normal operation. You may,
however wish to insert a signal processor such as a compressor/limiter or noise gate into the
channel signal path to prevent excessive peaks or to cut down source noise. The insert lets you do
this by breaking the signal path after the input pre-amp and before the EQ. Use a Y-lead or
suitable TRS jack lead to connect to the external processor. The insert operates at 0dBu line level.
Adjust the processor input and output levels for optimum signal level.
C HANNEL D IRECT O UTPUTS
The channel direct output taps the signal off post-fader (pre-fader if the internal link option is
changed) for connection to external processing or recording equipment. This is ideal for multitrack
recording during a live performance. Here each channel can be recorded on a separate track for
mixdown later. The output is impedance balanced on TRS jack. This means that you get the
benefit of interference immunity when connecting to outboard equipment with balanced inputs.
You can, of course, also connect to unbalanced equipment. The signal operates at nominal 0dBu
line level.
L-R M AIN O UTPUTS
These 3-wire balanced outputs on XLR connectors operate at a nominal +4dBu to drive
professional equipment over long cable runs without interference pickup. Connect to an amplifier,
of suitable power rating for the venue, to drive the PA loudspeakers. Or connect to a 2-track
recorder for studio or location recording.
