Facility Ports
46 Series mixer-ampliers are provided with two FACILITY
PORTS in the form of rear panel RJ45 connectors
22
. The
primary use of the Facility Ports is for the connection of
remote active modules such as the LM-2 or BT-1. The Facility
Port audio path includes a noise gate to help minimise
unwanted background noise from the external source.
If Mic-over-Music priority is enabled (see “Paging control and
mic priority” on page 16), the position of internal jumper
J17 determines whether an input at either Facility Port will be
reduced in level by 25 dB in the same way as the other Line
Inputs. By default, this ducking option is not enabled, but may
be overridden by moving internal jumper J17 from its default
setting (OFF) to ON. See page 27 for locations of PCB jumpers.
By default, an audio source connected to an active module
will be routed via Facility Port 1 to Zone 1, and via Facility
Port 2 to Zone 2. The music sources currently selected in
those zones will be muted and replaced by the Facility Port
audio. The Facility Port routing may be altered by moving
internal jumpers J5, J7 and J8 as follows:
• J7 determines whether audio at Facility Port 1 is routed to
all zones or only to Zones 1 and/or 3;
• in the latter case (above), J5 sets whether it is routed to
Zone 1 or Zone 3;
• J8 determines whether audio at Facility Port 2 is routed to
Zones 2 and/or 4.
Remote control functions via the
Facility Ports
The remote control functions (music source and level) of an
LM-2 active module connected to Facility Port 1 will only
control Zone 1, even if Facility Port 1 is routed to multiple
zones via jumpers J5 and J7.
The remote control functions (music source and level) of an
LM-2 connected to Facility Port 2 will only control Zone 2,
unless Facility Port 1 has been routed to all zones. In this
scenario, the remote controls of the LM-2 connected to
Facility Port 2 will be disabled.
Where a Facility Port is routed to more than one zone and it is
desired to have remote RSL-6 or RL-1 control of source and/
or level in the zones which are not controlled by the LM-2
remote control functions, then this can be achieved using the
REMOTE PORT for the additional zone(s) to connect separate
RSL-6 or RL-1 remote controls.
The various optional Cloud remote active modules operate
from DC power supplied by the 46 Series mixer-amplier.
The current consumed by each module is minimal and in the
vast majority of installations there will be no power supply
issues.
IMPORTANT: In order for the remote control
functions on an LM-2 module to operate
(with J7/J8 in the default settings), the Zone 1
and/or Zone 2 rear panel REMOTE PORT
SETTINGS DIP switches must be set to REMOTE. This will
disable the front panel SOURCE and MUSIC LEVEL
controls, and control of music level and/or source selection
will be available from the LM-2. LOCAL/REMOTE selection
should be left in LOCAL (switch up) when a BT-1, L-1 or
M-1 module is connected to the Facility Port. However, if
an RL-1 or RSL-6 remote control plate (or serial control of
source and/or level) is also being used in these zones, the
switch should be set to REMOTE.
IMPORTANT: Do not connect BOTH an LM-2
module (or an RSL plate connected via a BT-1
module) to a Facility Port AND an RL or RSL
Series plate to a REMOTE MUSIC CONTROL
PORT for the same zone that the Facility Port is routed to,
as the remote controls will conict.
IMPORTANT: If a Facility Port is assigned to
more than one zone, the remote control
functions only work on the lowest-numbered
zone that it is assigned to. So remote control
functions via Facility Port 1 can only ever control Zone 1
and remote control functions via Facility Port 2 can only
ever control Zone 2, unless Facility Port 1 is assigned to all
zones, in which case Facility Port 2 becomes redundant.
