Sennheiser Spectera ST 2110 integration enables native IP-based audio workflows

The move to native IP-based audio via SMPTE ST 2110-30 removes the need for external conversion hardware, reducing latency and complexity in the broadcast signal chain. By embedding Merging Technologies' ZMAN module directly into the Spectera Base Station, Sennheiser is positioning its wideband wireless system as a core infrastructure component rather than a peripheral. This shift aligns with the broader industry transition toward software-defined production environments where interoperability between wireless RF and wired IP networks is mandatory. Watch for the commercial availability of the ZMAN module in October 2026 to see how quickly Tier 1 broadcasters adopt bidirectional wideband for large-scale live events.

Sennheiser's Spectera platform represents a broader industry push to bring wireless audio into native IP production environments. At IBC2025, Sennheiser first unveiled Spectera as a bidirectional wideband wireless system capable of handling multiple channels over a single RF link, marking a departure from traditional narrowband wireless microphone architectures. The system uses a proprietary wideband waveform that allows simultaneous uplink and downlink communication between transmitters and base stations, a capability that aligns with the growing demand for real-time monitoring and control in IP-based production facilities. Competing wireless microphone manufacturers including Shure and Wisycom have also been developing IP-compatible base station designs, though none have yet announced native SMPTE ST 2110-30 integration at the hardware level.

The commercial and regulatory landscape for wireless audio in broadcast is shifting alongside the technology. The FCC's 600 MHz spectrum repurposing has forced wireless microphone operators to migrate into narrower frequency bands, creating pressure on manufacturers to deliver systems that operate efficiently in constrained spectrum while maintaining channel density. Sennheiser's Spectera addresses this by using a wideband approach that consolidates multiple audio channels into fewer RF carriers, reducing the overall spectrum footprint per production. In Europe, the European Commission's Radio Spectrum Policy Group has been evaluating shared access models for the 1.4 GHz band, which could open additional spectrum for professional wireless audio applications and benefit wideband systems like Spectera that are designed for flexible frequency operation.

Merging Technologies' ZMAN module, which provides the SMPTE ST 2110-30 interface for Spectera, is part of a wider trend of audio-over-IP hardware modules being embedded directly into production equipment. Merging Technologies announced that its ZMAN card supports AES67 and ST 2110-30 with sample-accurate synchronization for up to 128 channels, positioning it as a drop-in solution for manufacturers seeking IP connectivity without redesigning their hardware platforms. The module's integration into the Spectera Base Station follows a pattern seen in other production hardware categories, where SMPTE ST 2110 compliance has become a baseline requirement for new equipment purchases at major broadcasters. The European Broadcasting Union's Open IP initiative has published interoperability test results showing that ST 2110-30 audio devices from multiple vendors can operate together in mixed-vendor environments, reducing the integration risk that has historically slowed adoption of IP audio in live production workflows.
