RCM-4 INTRODUCTION
Page 1
The RCM-4 Room Combining Module provides
the means for simplified, central control of
zone-combining and source selection functions
in commercial sound systems.
Several kinds of control signals may be issued
by the RCM-4. Used with a compatible mixing
matrix system, such as the Oxmoor RMX-44, the
RCM-4 will generate the signals required to
cause multiple sound systems to be combined to
form a single system. In hotels or convention
centers, for example, systems in adjacent meet-
ing rooms may be combined when moveable
partitions are open to form a single, large hall.
Through the RCM-4, a user may also select
which source, or combination of sources, is to
be used in the combined system. The operator
may simply push a button, for example, to dic-
tate that a particular end of the room will be the
location of the head table or entertainment. By
not selecting the sources of any of the other
combined zones, the possibility that they might
contribute hum or other undesired noise is
eliminated.
The user may just as easily select multiple
sources, making it possible to plug microphones
or other audio sources into any desired inputs
within the combined zones.
The RCM-4 may be used to link remote volume
controls of multiple systems, using Oxmoor Cor-
poration, LLC’s DCA-2 Digital Control Attenua-
tor and RC-16 Remote Controls (Figure 3). This
may be accomplished with or without the room
combining function (Figure 5). Likewise, room
combining may be performed in systems with or
without remote volume controls.
In the example shown in Figure 4, no remote
volume controls are used. This leaves the Re-
mote Control jacks available for other switching
purposes.
