use switchers.

http://www.broadcasttools.com/product_list.asp

the 16x1 or SS 8.1 II are passive switchers. get one switcher for each
channel. then hook room 1 to ch one one each. room 2 to ch 2 and so on.

I've used both Elco and DL (the connectors on the SSL), I'd shy away
from the Elcos in any situation where they're going to be connected and
disconnected many times or used by ham-handed persons
(interns...students...etc).

Unless you "help" the mating/unmating process along, you will eventually
strip out the nut in the female recepticle (may take a year or several
depending on usage). Even then you can still use the connector by simply
pushing it forcibly into place, but it's not a very reassuring
connection.

Also the Elco pins are not well protected and can get fairly easily bent
or damaged. They do have a nice large connection contact though.

The DL style connector is actually pretty nice, the pins are somewhat
better protected, more so on the female side than the male. And the
actuation/locking handle is much easier to use. Smaller electrical
contact area, but it doesn't seem to be a problem over the long term
(connectors I installed almost ten years ago are still
trouble-free...but they haven't been unmated/mated more than a couple
times a year).

Be aware that you'll need to purchase a specialty crimping tool to crimp
the pins for either of these connectors, and they typically run well
over a hundred dollars US (shop around or borrow one!)

I'd recommend the DL connector.

Actually, since I am on the subject, what is everyone's favorite
multicore for permanent installation? 8 to 32 pair can be used in my
application and star-quad is not desirable due to conduit size, price
and relatively quiet environment. Of the three that I've worked with
- belden, mogami, canare - canare was my favorite, but that was
single line only.

Thanks again,

If it's a permanaent install why would you use multicore? use single
lines.

Belden 9180 is a 26 guage 110 Ohm foil shielded pair. You would be
able to get more than 140 strands of it into a 2" conduit ( just my
guess off the top of my head )

Then make your whips out of Canare L4 type multicore.

Do all your ground lifting in the harnesses that go to your
equipment. Or if you have rolling racks with multi-pins on them ( the
whole rack on one connector ) Lift stuff on the harness inside the
rack.

The Gepco stuff is allright but it can be a pain to solder to
multipins as the jacket peels back really fast. ( I've been soldering
Gepco to DB25s this week, and it's the sane as the Gepco i complained
about the last time i had to solder Gepco , 4 years ago)
