SimphoniX- Si-400

The name SimphoniX was derived from two key themes for the product line: Simple to use and Symphonic audio quality.

Our field research concluded that performance results of today's installed conferencing hardware were dependent of the skill level of the install technician. Most firms can not justify sending an experienced audio engineer to adjust every room or on all maintenance / trouble calls. SimphoniX is designed to have the same performance results regardless the skill level or experience of the installer.

Historically the bar for conferencing has been set to "telephone quality" sound. The emergence of improved voice fidelity, video tele-presence and a new generation of telephony demands CD quality audio that operates in challenging environments. SimphoniX systems are designed with hardware and speech algorithms that accommodate the full range of human hearing delivering clean, loud and clear audio.
