TecNec Intercom Straight Extension Cable 4 Pin XLR M to XLR F 6Ft
This cable cost about $17.95 and it is one of the best cable construction I have ever seen. It uses Canare Star Quad Cable with 4 Pin XLR Neutrik Connectors. Of course I had to cut off the male end and put on banana plugs. The shield on the Canare is braided and it took a bit of time to unravel it but with a bit of practice it can be done faster. One thing to watch out in getting a 4-pin XLR extension cable is that many 4-pin XLR extension cables are for used for power and have just two wires connected. The TecNec Intercom uses all four wires of the Canare Quad Cable to each of the four pins. It was not as easy to find the right cable but it work out in the end. I am going to have some interconnect cables made with Canare and it has one of the best RF interference rejection in the business.
Excellent find. That is a great cable at a fantastic price. It cost me over $20 for 10 feet of raw cable and 2 connectors. They offer both a straight and coiled version both using the Canare Star Quad. I'm going to link to it from my balanced cable how-to.
[UPDATE It's such a great deal I ordered a 10 and 15 foot cable for future use.]
I did make the mistake of buying a 4-pin XLR extension power cable with only 2 conductors. Luckily I was able to re-sell it on ebay.
This is what the Canare Star Quad looks like when cut open:
After you cut the cable you'll need to identify which wires connect to the 4 pins using a multi-meter's continuity function. When I made my 4-pin XLR cables from Canare Star Quad I marked the negative wires with a sharpie and used the blue wires as the right channel. For a speaker terminal cable you have the option of connecting the amp chassis to the cable's metal shield to provide a ground which will help protect the cable from RFI noise.
