SPECIFICATION DATA
Presentation-style conferences for up to 14 languages, where a floor and a single relay language are used.

IC-2Interpreter Control ConsoleThe Williams Sound IC-2 is an audio control center for
simultaneous interpretation of one or more languages. As astand-alone unit, it allows one or two interpreters to monitor
floor or relay sources, activate microphone inputs, and route theinterpretation signal to one of two language groups. Ideal forpresentation-style conferences for up to 14 languages, wherea floor and a single relay language are used. Can be used withWilliams Sound FM, IR and Digi-Wave™ transmitters for portableor fixed installations. Designed to meet international standards for
portable interpretation consoles.

Features• CAT5 audio bus offers simplified cabling, easy cascading tosupport additional interpreters.
• Built-in distribution amplifier and mini mixer reduce the need forexternal equipment and greatly simplify setup.
• Floor language feed-through• Interlocking microphone and CH2 (relay) output functions• Soft-touch buttons provide for smoother, quieter operation• Enhanced flexibility, providing each interpreter with multiple
microphone and headset options• Individual volume and tone controls ensure optimal listeninglevels• Five-year warranty© 2012, Williams Sound, LLC MCAT 091i
