Section 1 — System Description
Monitor Output Configuration
Monitor Output configuration allows a single Destination signal per con-
figured matrix to be sent to external monitoring devices (speakers, head-
phones, signal meters, video monitors, etc.). The physical configuration of
the Concerto frame will determine what type and how many monitoring
devices can be connected. For wiring information see
Monitor Cabling on
page 100 .
Analog Audio, Digital Audio (AES), Analog Video, and Digital Video (SD,
HD and 3Gb/s) signals can be monitored. Time Code and Port signals are
not monitored. The following tables will show the different supported con-
figurations and how they affect monitoring.
Analog Video Monitor Configuration
Analog Video modules use a BNC backplane with a single set of Monitor In
and Monitor Out BNC connectors, cannot be combined with any other
module type in a matrix, and they use internal bussing to support monitor
functions, so all outputs in the matrix are available. The
Monitor In connec-
tion is not used. One Destination signal is available to all of the Monitor Out
BNC connectors in the matrix. There is one Monitor connector per back-
plane, so in a 32x32 matrix there is one backplane, one connector, one mon-
itoring device can be attached. In a 64x64 matrix there are two backplanes,
and two connectors; two monitoring devices can be attached. The same
signal is sent to all the
Monitor Out connectors in the matrix. For cabling infor-
mation see Analog Video Monitoring on page 100 .
Digital Video Monitor Configuration
Digital Video modules use BNC backplanes with a single set of Monitor In
and Monitor Out BNC connectors per backplane, 3Gb/s, SD and HD modules
can be combined in a matrix, and they use external cabling to support
monitor functions, so all outputs in the matrix are available. All SD video
signals can be routed through either module making SD video available to
all outputs. The HD signal (1.485 Gbps) can only be routed through HD
modules; the 3Gb/s signal can only be routed through the 3Gb/s modules.
Therefore, the SD modules should be before the HD and 3Gb/s modules in
the frame.
