OPERATING YOUR BELTPACK
An RS-601 beltpack works with all previous versions of Clear-Com
party-line stations and beltpacks. It is the first single-channel
Clear-Com beltpack that is compatible with Clear-Com TW
beltpacks.
This means that you can wire several beltpacks together in a “daisy-
chain” or “home-run” configuration on a TW line that includes
RS-502/522 TW beltpacks as well as other RS-600 series TW
beltpacks. While the audio on the RS-601 will always be from pin 3 of
the XLR connector (channel B), it will still pass the channel A audio
through on Pin 2.
The RS-601 is not recommended for use with RTS-TW systems as
the frequency response curves and audio levels are different.
Clear-Com’s RS-603 series beltpacks are compatible with RTS-TW
systems.
