slot high and is fitted with six high density 62 way, ‘D’ type sockets; three for inputs and three for
outputs and 4 BNC connectors for MADI connection; 2 input and 2 output (functionality described
in section 6.2.2.1)
Each 9105 panel has a capacity of 36 x 36 stereo pairs (or 72 x 72 mono channels). Larger
routers can be constructed within a single frame by using multiple panels. Two panels can be
fitted together to provide a 72x72 stereo router, three for a 108x108 stereo router and four, for a
144x144 stereo router.
Figure 56 and Figure 57 illustrate rear panel port numbering using four Audio Modules and Rear
Panels in a single frame configured as a single logical level. The port numbering is dependant on
the MADI mode the router is set to. Both illustrations show the modules in logical order but if the
destination offset is set correctly on the module it will map itself correctly and recognize the right
address range. This means systems can be expanded by adding cards to any empty slots.
Tables detailing the port numbering and configuration can be found in Sections 6.2.6 and 9.1

Due to the very high density of these connectors, and the difficulty wiring them, Snell have
designed a breakout system which takes multiple 62-way D-Types and converts them to standard
screw fix connectors to ease wiring. Details of breakout board and wiring in Section 8.2
Alternatively Snell have custom designed a connector shell for the 62-way connector. It’s
designed to accommodate up to three multicore cables or multiple separate twisted pairs. Typical
cables which can be used are Canford FSM-12 (12 pairs). The mating connectors’ kits are:
