MCS ROOM COMBINING SYSTEM INTRODUCTION
The MCS TM Room Combining System combines up to
eight rooms in any combination. A non-volatile
memory feature preserves system settings in the event
of a power failure.
Using one of Oxmoor’s intuitive-designed, custom
Master Control Panels, an operator may easily combine
the audio of up to eight rooms and synchronize their
remote volume controls, select sources from the
combined rooms and mute speakers at head-table
locations. A volume control on the rack-mounted
Master Volume Panel is switch-assignable to provide
audio level adjustment for any room.
A typical MCS system would also include a wall-mount
Room Panel in each zone. The Room Panel offers a
rotary audio level control and switch selection of
background music or a local sound source. As on the
Master Volume Panel, the volume control is Oxmoor’s
well-established RC-16 that features a unique “Virtual
Pointer
TM ” LED to show system level.
At the heart of the MCS Room Combining System is a
self-powered, 5.25" rack-mount Mainframe. The
Mainframe contains Logic, Audio and Control cards.
The MCS-LC Logic Card has a balanced input and a
volume control for a Music/Page source. “Logic”
contacts permit paging to be heard in rooms where
background music has been selected without interfering
with sound system usage in other areas. Upon
activation, the PAGE function temporarily overrides
room volume controls, its level defaulting to that
established by the COMBINE LEVEL "MUSIC" control
located on the card.
An Audio, or “Line Input” Card (MCS-LI), is used for
each zone or room to be controlled. Each card provides a
balanced audio input and output, a trim pot for
adjusting the audio input level, remote volume
connections, and LOCAL or MUSIC SELECT with
TALLY status.
Communication between the Master Control Panel and
the Control card in the system Mainframe follows PA-
422 protocol. As an alternative to the Oxmoor Master
Control Panel, system control may come from a PA-422
control device or contact closures working in concert
with Oxmoor’s MCS-IB Interface Box.
