Hospital Operating Theater
Audio System Requirements
- Operating room, control room and external VTC require echo-free audio conferencing among them.
- 2 exclusive modes of hands-free conferencing while in the operating room: “Headset mode”, or “Room mic mode”.
- 2 gooseneck mics and 2 boundary mics in control room connect to DSP via Dante™ network.
- Non-verbal signaling system between both rooms using a push-button wall panel in each area.
- Volume control, preset and privacy mute triggering within both areas.
- Secured comprehensive system control from within the control room.
- Automatic ducking of operating room music when the operator from the control room speaks.

Solution Overview
| Requirement | Notes |
|---|---|
| Echo-free conferencing among all areas | The Radius AEC has dedicated DSP processing reserved exclusively for echo cancellation. |
| The ability to switch between “headset mode” or “room mic mode” in the operating room | Two presets were created in the main routing matrix in Composer. These are easily triggered via the ARC-3 in the operating room and the SymVue panel in the control room. |
| 4 Dante-enabled mics in the control room | Audio-Technica ATND971 and ATND8677 Dante-enabled mics are natively supported in Composer, allowing for seamless integration. |
| Non-verbal signaling system | A push-button wall controller in each room is used to trigger logic modules which control the LEDs in both ARCs, as well as the SymVue control screen. |
| Control of volume, preset-triggering, and privacy mutes in the system | Accomplished with an ARC-3 in the operating room and an ARC-K1e with SymVue in the control room. All programmed using Composer. |
| Secured control of the entire system from within the control room | A password-protected SymVue control screen generated within Composer. |
| Automatic ducking of operating room music | The Radius AEC programmed from Composer with a Ducker module in-line with the operating room music. |
Radius AEC
- Dedicated AEC processing, with 8 AEC inputs, 3 aux inputs, 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.
ARC-3
- 32 menus, each with up to 32 items for controlling basic audio functions or complex logic-based events including volume, preset and source selection, room combining and more.
- Bright, crisp 256×64 pixel OLED display is graphic and multi-lingual capable.
- Capacitive touch user interface with LED side lighting provides instant operational feedback.
ARC-SW4e
- 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.
ARC-K1e
- It looks like a single volume control but it’s actually two. Push the knob in to toggle between the two rotary encoders. An LED indicates the active control.
- An 8-segment LED ladder shows the volume level.
- Hardware lockout pins accommodate an installer supplied key switch.
- Power and signal arrive and depart via CAT-5/6.
- Supports “idle” mode for light-sensitive environments such as theaters.
- Furnished with a standard, white, single gang Decora faceplate and splash resistant overlay.
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 DSPs 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.
