bining System consists of:
• RCM-4™ Logic Module
• RMX-44™ Mixing Matrix
• DCA-2™ Digital Control
Attenuator
• RC-16™ Remote Controls
Using these components, Oxmoor
offers two-room, three-room, and
four-room combining systems
with volume control.
As a matrixing and level control
ensemble, the combining system
is positioned between the linelevel outputs of the individual
zone mixers and the inputs of their
power amplifier.
RCS ROOM COMBINING SYSTEM
At the heart of the system is the
RCM-4 Room Combining Module. The RCM-4 sends out several
types of control messages: it delivers both zone-combining and
source-selection commands to an
RMX-44 Mixing Matrix. The block
drawing illustrates an optional
Control Panel which serves as the
module's user interface.
When combining zones, the RMX44 mixes all signal sources (mixer
outputs) within the combined
zones. Also, all RC-16 Remote
Controls within the combined
zones will be linked together and
forced to a common preset level.
This allows all RC-16s in each combined zone to serve as master level
controls over all speakers in the
combined system.
The combining system may be
user programmed for two different modes of operation when

zones are combined. One configuration allows the RMX-44 to mix
all sources within the combined
zones. Because all sources within
the combined zones are active,
microphones, etc. may be plugged
in wherever desired within the
combined zones.
The second configuration mutes
the sources (using the Mixer Mute
Switch) of the combined zones,
allowing the user to select a source
(mixer) or a combination of sources
RCS-4CPS Room Combining System
to be used within 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.

RCS FEATURES & SPECIFICATIONS
• Compatible with most existing mixers and amplifiers.
• Up to 4 independent "local" sound systems, such as
adjacent banquet or meeting rooms, may be treated
as "zones" and instantly combined to create one larger
system.
• A mix of 2, 3, or 4 zones may be combined without
sacrificing the autonomy of those excluded.
• The RCS may be programmed to mix all sources
(mixer outputs) within the combined zones, allowing
source microphones, etc., to be plugged in anywhere
desired.
• The RCS may be programmed to mute all sources
(mixer outputs) within combined zones, allowing user
to selectively activate sources within the combined
zones.
• The RCS offers a Wake-Up level control. On power
up all remote volume controls are reset to a predetermined level.
• Remote audio level control is available for each independent zone using RC-16s.
• Each RC-16 Remote Control has a unique LED array
which provides a Virtual Pointer to show system level
in 3 dB steps.
• The standard system configuration allows all RC-16
Remote Controls to be linked together within combined zones. All RC-16s are in sync and will track
“up” or “down” adjustments made at any of the RC16s within the combined system.
SYSTEM CONFIGURATION
The RCS is available as a two-room, three-room, or
four-room combining system.
