  1. What does the Infinium C1 Controller do?
    The C1 controller is the central control hub of the Infinium Auracast™ system, managing audio distribution, system configuration, and transmitter coordination across a deployment. It enables centralized control of multi-stream audio in large or multi-room environments.
  2. How does the Infinium system scale across large deployments?
    The controller’s Enhanced Scale & Management (ESM) features allow the Infinium system to 150 transmitters for large deployments. Additional scalability is achieved through network segmentation and multiple controllers for larger deployments.
  3. How are transmitters organized and managed in the system?
    Infinium’s web interface includes many ESM features to help organize and manage multiple transmitters, including a spaces-based feature that allows transmitters to be grouped by room, zone, or area; transmitter naming option for easy identification; and coordinated transmitter arrays that enable seamless listener movement across large or multi-room environments with consistent audio coverage, to name a few. These features simplify navigation, system control, and management across complex environments.
  4. What are coordinated transmitter arrays?
    Coordinated transmitter arrays allow multiple transmitters to broadcast the same audio signal across a space. This enables listeners to move freely between areas while maintaining a consistent listening experience.
  5. Can the Infinium C1 integrate with existing AV systems?
    Yes. The C1 controller includes native Dante® integration for seamless audio networking and supports analog inputs. It also features an open API for integration with third-party AV control systems and smart building platforms.

    The system can be configured and monitored through an intuitive web-based interface or directly from the controller’s front panel. This provides flexible local and remote management options for AV teams.
  7. Does the C1 Controller include a transmitter or receiver?
    No. The C1 is a standalone controller. Infinium transmitters and receivers are sold separately and deployed as part of a complete system.
  8. How are secure audio channels managed?
    The system supports secure channel management with PIN-protected access. This allows venues to offer both public and private audio streams for different applications.
  9. What types of audio applications does the C1 support?
    The C1 supports assistive listening, audio description, language interpretation, and program audio delivery. Multiple audio streams can be managed and distributed across the same system.
  10. Is the Infinium system suitable for large or multi-room facilities?
    Yes. The system is designed for enterprise-scale deployments, including campuses, transportation hubs, theaters, and other large venues where centralized control and scalability are essential.
