Priorities
The 46-120 offers several options for determining what
happens to music signals when announcements are made.
Mic-over-Music priority
Fully automatic, voice operated priority is available for the mic
inputs. This is selected by internal PCB jumper J6, which should
be set ON (the factory default setting) to enable priority
operation. When enabled, all music signals will attenuate by
approximately 30 dB when the microphone is used (a process
often referred to as “ducking”); after the announcement, the
music signals will restore smoothly to their former level, over
a period of approx. 0.5 s.
The Priority setting applies to both microphone inputs, and a
signal at either MIC 1/TEL or MIC 2 input will initiate ducking.
If Mic-over-Music Priority is not enabled, microphone inputs
will be mixed with the selected music signal in each zone at a
level determined solely by the front panel controls.
See page 30 for location of the internal jumpers.
Line 6 priority
It may sometimes be necessary for one music input to have
priority over all the others; for example, a jukebox in a bar,
or a digital sound store programmed to make automatic
announcements in a public space. Input
LINE 6 may be set
to have priority in Zone 1 over whichever source is selected
for the zone by its
MUSIC SOURCE control. This priority
is set by moving internal jumpers J14A and J14B to the ‘ON’
position. (The default setting is ‘OFF’.)
When the priority is selected, a signal present at Line 6 will
force Zone 1’s source selection to that input; when the signal
disappears, the previously-selected source will be restored
over the time constant selected by J15 (3, 6 or 12 s).
Note that on the 46-120, Line 6 Priority is only effective in
Zone 1. During Line 6 Priority operation, Zones 2, 3 and 4
will continue to output their currently-selected music source.
See page 30 for location of the internal jumpers.
Mic-over-Facility Port priority
If an LM-2 remote active module is in use in Zone 1, it is
possible to give a microphone connected at the 46-120
itself (at MIC 1/TEL or MIC 2) priority over input sources
connected at the module. This might be desirable in function
rooms, for example, where building-wide announcements may
need to interrupt any local use.
This priority is set by internal PCB jumper J7. The default
setting is ‘OFF’; in this position microphones or other sources
connected at remote input modules will be autonomous
and will not be overridden by announcements made via the
mixer’s mic inputs. Setting J7 to ‘ON’ will give priority to
Mic 1 or Mic 2. The release time following an announcement
is approx. 0.5 s.
Note that this priority is independent of the local MIC
PRIORITY function which can be selected on the remote
module.
Control
CDI-46 digital interface
The optional CDI-46 Digital Interface card permits the
46-120 to be controlled by either RS-232 serial data or
TCP/IP commands via an Ethernet connection. Abridged
fitting instructions can be found at page 27, and connection
information at page 18.
Full operating instructions for the CDI-46 are
included with the card itself. The following manual
sections are intended to give a brief overview of
the card’s remote control features.
Remote control via RS-232
The RS-232 serial port’s default parameters are as follows:
• Baud rate: 9600
• Word length: 8 bits
• Stop bits: 1
• Parity: none
The port is bi-directional.
The port parameters may be altered using the web browser
GUI accessed through the Ethernet port (see following page).
Examples of some basic commands are given below:
