Audio connections

Each audio connection on the CAB and NION products is a single, three-wire, balanced

analog circuit. The connections are identical for both microphone, line input and line output

connections. We recommend that audio connections are made with high quality shielded wire.

Note: As with any electronic connection, care should be taken to ensure that the termination is

solid. There should be no stray wire strands, kinks or nicks in the wire jacket for a proper

termination.

CAT 5 connections

Category 5 cable, or CAT 5 as it is commonly known, is a wiring standard that consists of 8

conductors, identified into 4 pairs, and although only two of these pairs are used, all four are

terminated.

It is a UTP (Unshielded Twisted Pair) configuration. The cable is coupled to in-line RJ-45

connectors, also a Bell/AT&T standard. Special crimping tools are required to make the

termination; these are widely available, as are the connectors.

Just like telco wire, there are stranded and solid varieties of CAT 5 cable. This is important to

know, because the RJ-45 connector is different for each type of wire. The standard bent tine

connector is intended for use with solid core wire, and the aligned tine connector is for use

with standard wire. The bent tine connector will generally work on stranded wire, but not the

other way around.

The EIA standard requires no more than 1/2 inch be left untwisted. More than 1/2 inch of

untwisted cable will affect performance at high bit rates. Although only 2 of the 4 twisted pairs

are used for Ethernet, it is important that all pairs be terminated, and that the conductors be

twisted together in pairs. The illustrations should give you the basics for getting your cables,

and your audio system up and running. Although pre-made, molded style cables are preferred,

they are usually impractical, since your cabling route, distance and locations are based on the

jobsite conditions and not your test bench. Additionally, you will need rack wiring, and bulk

cable is the preferred way to dress off a wire harness.
