Benefits

Designed to help reduce operational cost.

Operating in the licence-free 1.9 GHz band, SpeechLine Digital Wireless avoids ongoing spectrum costs and simplifies deployment.

Centralised monitoring and control via Sennheiser Control Cockpit supports efficient system management, helping to reduce maintenance effort, minimise servicing requirements, and make better use of internal resources.

Integrates into existing IT & AV infrastructures.

SpeechLine Digital Wireless integrates smoothly into existing infrastructures using established standards such as Dante™ audio networking and Power over Ethernet (PoE).

Dual Ethernet connectivity supports flexible deployment, while compatibility with third-party systems enables operation as a standalone speech solution or as part of a broader AV environment.

Centralised setup and system management.

Sennheiser Control Cockpit provides a clear overview of system status across rooms and locations, supporting consistent configuration and monitoring.

Automatic frequency and interference management removes the need for manual RF coordination, while remote access to system parameters enables efficient day-to-day operation across deployments.

Ready when you are.

SpeechLine Digital Wireless is designed for immediate use, with microphones that are ready as soon as they are removed from the network-enabled charging station.

With up to 15 hours of battery life, the system supports reliable operation throughout the working day without interruption.
