Cable for 6 pin Clearcom

Clearcom uses only 4 wires (known as pins on the connectors) on their two channel (A and B) headsets. if you are only using one channel intercoms, you could use a regular xlr cable and only connect three wires. otherwise a four wire cable is good enough. we use them to make our own cables....alot cheaper than buying them at "50 bucks for a 10 footer".

pin 1 is for common
pin 2 is for +30 vdc power
pin 3 is for intercom b
pin 4 is for intercom a

pins 5 and 6 are not used as of this time.
 
The headsets use XLR4, but the two channel wired beltpacks use XLR6 to carry both channels A and B. Look at the attached picture. The two connectors on the left are the 6-pin In and Out/Through connectors. On the right is the 4-pin connector for the headset. Some setups use an XLR6 to 2 XLR3 splitter to connect directly to the base station.

Well yes they are... They are the program feed and reticulating it allows individuals to adjust how much program they get in their cans. This assumes that program is connected at the head end...
 
Also be careful of the connectors used, as the note for the RS-602 states:
Note: The beltpack’s intercom connectors use the Switchcraft-style 6-pin configuration. If ordering Neutrik 6-pin plugs to make a cable or patch panel, specify that you need the Switchcraft pin configuration. This configuration usually has an “S” suffix at the end of the Neutrik model number.
I believe that this applies to all Clear-Com 6 pin connections.

It appears that Pins 5 and 6 were used for Program audio on the old RS-201 (for which Belden 8777 was the recommended cable), then those pins were later apparently not used for the now discontinued RS-502/522, however the current RS-602/622 appears to again be using Pins 5 and 6 for Program + and - respectively. So perhaps their being used and their not being used are both correct, it all depends on what devices are connected.

correct, we use the 502 clearcomms and as long as you have the six pin connectors, you may use three or four conductor wire.
