[SML] Intercom junction hub wiring best practices

[Ray Gibson]

Hello,

I've come upon an ancient com system wiring where the master unit and
beltpacks were recently upgraded. There's a little hum on the line, which
obviously could be due to a variety of factors that we plan on isolating
and fixing.

The current wiring is hub and spoke, with the two hubs being booth and
stage. In addition to the regular daisy chaining on some of the spokes, the
hubs are wired together with really old 66 blocks. Is this style standard?
The blocks used to have many other functions in the past but have outlived
their usefulness and I'd like to replace them with a more efficient unit.
My question is, what to use? Regular screw terminal blocks? Wire nuts?
Patch panel with mults?

Splitting all the lines while installing the replacement will give me the
best opportunity to isolate the hum and replace any components as necessary.

This is single channel clearcom running over regular xlr patch cables.

I have browsed through Telex's "Handbook of Intercom System Engineering"
and while having learned quite a bit since, the answer to my question is
still unclear.

Thank you,

Ray
