Splitter Boxes
Ensure that you split the digital intercom lines within a shielded enclosure. For example, a 1RU shielded chassis, such as Middle Atlantic CH1, and daisy-chained XLR connectors (for example, Neutrik NC3MD or NC3FD).
To prevent crosstalk between lines, ensure that each shielded splitter box contains only one digital intercom line. If you have to split more than one digital intercom line, use multiple shielded enclosures.
