System Description
The Concerto Multi-Format Routing switcher is a matrix-type video/
audio/data switching system designed for use in broadcast, teleproduc-
tion, and networking facilities.
The module slots in the frame are not format sensitive. The slots are phys-
ically configured by plugging in any Concerto module and associated
backplane into any slot. Each module is a complete 32x32 matrix containing
inputs, outputs, and crosspoints. By inserting the modules in the frame in
different configurations, such as two digital video modules in adjoining
slots, matrices of 32x32 to 128x128 are created.
CAUTION If a module is plugged into an incompatible backplane it will cause damage.
Three rack frame versions are available:
• 4 RU Concerto frame with two slots for modules. This chassis, which is
sometimes referred to as the “Concerto 64” frame, can use the lower
cost 64x32 modules.
• 7 RU Concerto frame with four slots for modules. This frame can be
loaded with any four modules, with the exceptions that only two HD
video modules can be installed when there are two other modules; or if
three HD video modules are installed then the fourth slot must be left
empty.
• 8 RU Concerto+ frame with four slots for modules. This frame can be
loaded with any combination of four modules including four HD video
modules.
Module signal formats include:
• Analog (audio and video),
• Digital (AES audio, SD, HD and 3GB/s video
1
), and
• Data (Time Code and Port) modules.
Two video reference inputs, allow assignment of both PAL and NTSC ref-
erences to the same frame.
In addition to supporting up to 3Gb/S , the module also supports 270 Mb/
S "standard rate" SDI/DVB-ASI as well as 1.5Gb/S HD SDI.
