6.6 Microphone over Music priority
The CX163 provides a facility
whereby the microphone signal can
be given priority over music signals in
any particular zone. When a signal is
detected on the mic input, all music
signals are attenuated by 30dB. Once
the microphone channel is clear, the
music will restore to the previous
settings.
Microphone priority can be triggered
by the appropriate zone access
contacts, or it can be triggered when
a signal is detected on the
microphone input. The triggering
mechanism can be selected on the
respective jumpers for each of the
zones: J11 (Z2), J14 (Z1), J15 (UTIL).
Leaving the jumper disconnected
disables microphone priority in that
zone.
Jumper positions:
AVO: Priority is triggered when a signal is detected on the microphone input and the
zone is being accessed.
ACC: Priority is triggered as soon as the access contact for that zone is shorted to
ground.
OFF: This position is not marked, but can be achieved by removing the jumper
altogether
NOTE: When removing a jumper link, we advise that the link be left connected to one pin of the
jumper header to prevent accidental loss.
J15 jumper positions are reversed from J11 and J14.
7 Output Details
Each output terminal is balanced, using a 3 pole ‘Phoenix’ type connector. The outputs can operate into
loads as low as 1k2
Ω . The nominal output level is 0dBu (775mV) but the mixer can operate with a wide
range of signals up to a maximum output level of +20dBu (7.75V). For balanced interconnections, 2-core
screened cable should be used. Connect the screen to pin 1, the reverse phase signal (normally blue or
black) to pin 2 and the in-phase signal (normally red) to pin 3. If you wish to connect any zone output to
an unbalanced input, connect the cable screen to pin 1 with the hot connection (inner core) to pin 3 and
make no connection to pin 2.
Note that unbalanced signals should not be run over long distances. It is recommended that you only
use unbalanced connections between pieces of equipment that are in the same rack.
