1-6 7500 Series Instruction Manual
Section 1 — Overview
7500NB systems can be expanded in increments of 64 inputs/outputs to as
large as 1024x1024. They are assembled using standard Grass Valley router
frames, distribution amplifiers, Ethernet switches, and in some cases
custom cables. Contact Customer Service for specifications and ordering
details.
Table 1-1 shows the number of crosspoint modules required to
create configurations up to 1024x1024. Table 1-2 and Table 1-3 shows the
number of input and output modules needed to create configurations up to
1024x1024.The number of input modules needed is affected by how many
outputs the system contains.
