Connectivity and compatibility

The system’s bodypack transmitter accepts any compatible lavalier or headset microphone via a locking 3.5 mm connector, providing flexibility for different presentation styles. The receiver’s Ethernet port allows integration into networked audio setups, enabling centralized control and monitoring through Sennheiser’s Control Cockpit software. This makes it easier to manage multiple units in venues where equipment is mounted out of reach.

Performance and reliability

True diversity reception ensures a stable wireless connection by switching between two antenna paths to avoid dropouts and interference. The wide tuning range and large number of selectable frequencies help avoid crowded channels, which is essential in busy conference centers or lecture halls. The robust metal receiver chassis and reliable battery options support long-term use in demanding professional environments.

Ideal uses and environments

This wireless microphone system fits well in corporate meetings, educational lectures, worship services, and training sessions where clear and consistent audio is critical. Its ability to support many channels simultaneously and remote network control makes it a strong choice for venues with multiple rooms or complex audio setups. Presenters benefit from the bodypack’s adjustable gain and secure microphone connection, allowing them to focus on their message without technical distractions.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
