A Comprehensive Guide to Clear-Com Analog and Digital Partyline Systems

Clear-Com’s original development of Partyline intercom effectively created the platform to coordinate live performance technical teams as now we know it. As part of our 50th anniversary, it is an appropriate time to document our Partyline communications platform—both analog and digital formats in this Reference Guide. This Guide explains the technology in general terms and comprehensively covers the Partyline concept, as opposed to how it is handed in the specific manuals of a particular product.

RF Performance: FreeSpeak II Co-Existence with Wi-FI Technology

Clear-Com’s FreeSpeak II (FSII) 2.4 GHz wireless intercom system offers unparalleled multi-channel duplex audio and radio performance for both studio and external use. With the rise in Wi-Fi and other 2.4GHz systems in use at sports and events, often provided to complement the action on mobile devices or for remote control of lighting and score boards, how will FreeSpeak II perform in the same RF space? This paper describes the technology within FSII to provide high radio performance in dense RF fields and offers suggestions for mitigating interference during the installation.  Continue...

Integrating Production Intercom Systems Using Existing LAN/WAN IP Networks within Broadcast and Live Events

Dependable internal communications for the staff of an event is a necessity. A quality presentation can only be achieved when personnel involved in the production can communicate quickly and reliably. When a variety of different technologies are involved, achieving this can be challenging.
This white paper is not a discussion of “native” IP systems that operate only in the IP domain. Its purpose is to explain methods of connection of two-wire “party-line” and four-wire intercom systems by using existing and available LAN and WAN IP network technology. Read on...
