- Courtroom, analog phone lines and VTC require echo-free audio conferencing among them.
- 10 gooseneck mics arranged around courtroom connect to DSPs via Dante™ network.
- One dedicated sidebar microphone used exclusively for archival purposes.
- A bench-controlled “Sidebar Mode” instantly mutes all microphones (except sidebar mic) while routing pink noise into the system for private Sidebar conversations.
- 5 discrete recording channels ensure a clear trial archive, including: judge/sidebar mics, witness, defense, prosecution and a full courtroom mix.
- Secured comprehensive system control from clerk’s desk, including mic mix, conferencing levels and instant privacy muting.
- Simple controls at the bench, including zone volume, “Sidebar Mode” triggering and privacy mute.

Solution Overview
Requirement | Notes |
---|---|
Echo-free conferencing between all areas | The Radius NX has dedicated DSP processing reserved exclusively for echo cancellation. |
Ten Dante-enabled mics for full coverage in the Courtroom | Audio-Technica ATND8677 Dante-enabled mic base stations are natively supported in Composer, allowing for seamless integration. |
The ability to switch between “Sidebar On” and “Sidebar Off” presets | Two presets were created in Composer to toggle between muting all room mics/routing pink noise into system and normal operation. Easily triggered by an ARC-EX4e at the bench and the SymVue panel at the clerk’s desk. |
Uncomplicated controls at the bench | An ARC-K1e + ARC-EX4e combination provides easy-to-understand control over necessary functions from the bench. |
5 channels are routed to a recording device for archival purposes (including dedicated Sidebar mic) | Routing/processing is accomplished via Composer’s myriad DSP modules. A Gain-sharing Automixer ensures all sources are automatically captured at adequate levels. EQ and additional dynamics processing are in-line and set by the integrator. |
Secured control of the entire system from the clerk’s station | A password-protected SymVue control screen generated within Composer provides full system control. |
Volume controls for both defense and prosecution areas | An ARC-K1e at each table for zone volume with clear LED level indication. |
Automatic level adjustment of presentation sources | Automatic Gain Controller DSP modules for both podium AUX inputs help to regulate a variety of presentation input levels. |
