Figure 3 shows the Oxmoor four-room combining sys-
tem. At the heart of the system is the RCM-4 Room Com-
bining Module. The drawing includes a Control Panel
which serves as the module's user interface. The RCM-4
delivers both zone-combining and source-selection sig-
nals to an RMX-44 Mixing Matrix.
When combining zones, the RMX-44 mixes the appropri-
ate signal sources (mixer outputs) within the combined
zones. Also, all RC-16 Remote Controls within the com-
bined zones will be linked together and forced to a com-
mon preset level. This allows all RC-16s in each combined
zones to serve as master level controls over all speakers in
the combined system.
The RCM-4 Room Combining Module may be user con-
figured for two different modes of operation when zones
are combined. One mode of operation allows the RMX-44
to mix all sources within the combined zones. Because all
sources within the combined zones are active, micro-
phones, etc., may be plugged in wherever desired within
the combined zones.
The second mode of operation mutes the sources of the
combined zones, allowing the user to select a source or a
combination of sources to be used within the combined
zones.
The user can select where the head table will be –where
the entertainment microphones will plug in – without any
chance of hum, buzz, or ambient noise from unused
sources.
Figure 3.0: Typical Four-Room Combining Application *
For the application shown, we recommend the Oxmoor RCS Room Combining System. When purchased as a package, the Room Combining System
offers substantial savings over the cost of the individual pieces. The Control Panel shown is one of four optional control panels offered only for the
RCS System. Input Source Select buttons are options on each Control Panel. *
