Courtroom
Audio System Requirements
- 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.
- Zone volume controls for both defense and prosecution.
- Automatic gain adjustment at presentation podium inputs to handle a wide variety of unknown sources.

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. |
Radius NX
- Dedicated AEC processing, with 8 AEC inputs, 3 aux inputs and 8 outputs.
- Universal DSP building block with a 64×64 channel Dante network audio port.
- Configurable input/output option card slot reduces total system cost.
- Add an Analog Telephone Interface card, or a VoIP card, for an all-in-one conferencing solution.
- Industry-leading audio performance specifications.
2 Line Analog Telephone Interface Card
- 2 PSTN (POTS) lines – Telco Connections via RJ11.
- Fits into Edge and Radius card slots for a multitude of applications – e.g. teleconferencing, paging, remote monitoring and broadcast.
- Deskset functionality – Answer, dial, redial, speed-dial, ignore (DND), decode (DTMF), ID callers, detect progress, monitor line status and faults, plus more.
ARC-K1e
- Single volume knob with two encoders. Can be used to control one or two volume faders.
- An 8-segment LED ladders shows the volume level.
- Power and signal arrive and depart via CAT-5/6.
- Supports “idle” mode for light-sensitive environments.
ARC-EX4e
- Modular user wall panel with four buttons that are programmed as momentary, latched or radio.
- Well-suited for control of mute, source selection and presets.
- Tri-color LEDs provide user feedback. LEDs and buttons may be linked or programmed independently.
Composer
- Composer is an award winning CAD program used to create site file designs perfectly suited to each and every application.
- Management of all aspects of audio routing, processing, mixing, user control and security for Edge, Radius and Prism series DSP’s and accessories.
- Native configuration and control of select Dante third-party endpoints.
- Over 600 DSP modules and dozens of control and logic modules.
SymVue
- SymVue is a network-based application for Windows PCs, touchscreen PCs, and tablets.
- Control screens are authored in Composer from which SymVue runtime versions are generated.
- Important control parameters from one or multiple DSPs are easily consolidated onto user friendly screens.
- Multiple and concurrent instances of SymVue may be deployed across a control network.
- Parameter changes are always in sync between Composer, ARC Wall Panels, ARC-WEB, third-party controllers, and SymVue.
