TANDEM-300 may be fitted into three of the Crystal Vision range of rackframes:
•
FR2AV 2U frame for up to 12 TANDEMs or other single height Crystal Vision
modules,
•
FR1AV 1U frame for up to 6 TANDEMs or other single height Crystal Vision
modules
•
DTB-AV 1U Desk top box for up to 2 TANDEMs or other single height Crystal
Vision modules.
There are six types of rear connector available to cater for all frames and to provide system
flexibility by allowing a mix between access to all connections and maximum module
packing density. Both balanced and unbalanced audio connectors are catered for.

The single-width rear connector achieves maximum card density with up to 12 TANDEM
cards in a FR2AV frame, albeit at the expense of losing the second buffered SDI outputs.
This solution also demands a high-density multiway connector for balanced digital audio
I/O, but all connections, including GPIs and analogue preview monitoring are available.
The loss of second SDI output can be avoided by using a taller rear module. A double-
height single card rear module allows access to all connections at six cards per 2U frame
and three cards per 1U frame. A special all-connection triple card rear module achieves
nine cards per 2U frame.
There are also double-height single-card and quad-height triple-card rear modules available
with BNCs for unbalanced
digital
audio. However, the double-height version does not have
the second SDI output and the triple does not have the second digital audio outputs. Triple
height modules only fit in the FR2AV 2U frame
