CHANNEL INSERT A single 3-pole TRS jack carries the unbalanced
insert signal. Tip = send, Ring = return, Sleeve = common ground. The
channel insert is post-HPF, pre-EQ and operates at 0dBu. Use these to
patch in line level signal processing equipment such as compressors,
gates or outboard EQ. The wiring of a suitable cable is shown in the
diagram:
MIX INSERT Each mix is provided with an insert socket for patching in
an outboard signal processor. When working with stage speakers this is
typically a 31 band graphic or a multi band parametric EQ used for ringing
out feedback or tuning the speaker response. When working with in-ear
systems this may be a dynamics processor with limiter to protect the in-ear
user’s ears from unexpected signal peaks. AFL monitors the signal after
the insert so that the engineer can listen to the effect of the processor. A
single 3-pole TRS jack carries the unbalanced insert signal for each mix
output. Tip = send, Ring = return, Sleeve = common ground. The insert is
pre-fader and operates at a nominal -2dBu line level.
MIX OUT The 12 mix outputs are provided on balanced XLR, pin 2 hot.
These produce +4dBu when the meters read ‘0’. The mix outputs feed the
stage monitors, typically wedge loudspeakers and in-ear personal
monitoring systems. They can also be used as effects sends, recording
feeds and for other special requirements.
MONITOR OUT The console stereo monitor is simultaneously sent to
the headphones amplifier, a pair of balanced XLR outputs and a pair of
impedance balanced TRS jack outputs. The XLR output operates at
nominal +4dBu, the TRS jack at -2dBu. The XLR and jack outputs can be
connected to the engineer’s local speaker or in-ear monitoring systems.
The output may be switched for mono or stereo operation.
HEADPHONES OUT The console is provided with two headphones
sockets on the front panel – a ¼” TRS jack and a mini 3.5mm jack for
plugging in standard headphones or monitor ear pieces similar to those
worn by the performers.
EXT IN Unbalanced ¼” jacks, 0dBu line level signal. Feeds the stereo
AFL mix when switched on. For mono signals, plug into the left input only.
Use this input to add an external signal such as the monitor output from an
in-ear transmitter rack or remote talkback to the engineers monitor.
USER OPTION Blank plates are fitted here as standard. The Sys-
Link II console expander option kit may be fitted here.
