Whether you’re running a single handheld mic or a fleet of transmitters, you can deploy multiple channels with confidence, reducing interference and ensuring consistent audio quality across sessions.
• Seamless, plug-and-play installation: The G4 300 Series is built for quick setup in busy spaces. Receivers are compact and easy to mount, with intuitive pairing and synchronization between transmitter and receiver. Plug in to a mixer or PA system and you’re ready to go. IR sync options simplify pairing, so educators and presenters can focus on delivering their message rather than wrestling with settings.
• Exceptional audio quality you can trust: Sennheiser’s renowned microphone technology delivers crisp, clear voice reproduction with generous headroom and low self-noise. The system preserves natural dynamics, making every speaker heard with warmth and accuracy, whether you’re delivering a lecture, presenting quarterly results, or leading a training session.

How to install Sennheiser Wireless Microphone System

1. Unpack and inspect components: Ensure you have the receiver(s), transmitter(s) (handheld or belt-pack), antennas, power supplies, and necessary cables. Verify that all items are present before installation.
2. Choose the installation layout: Position receivers in a central, elevated spot with a clear line of sight to transmitters where possible. Use appropriate rack mounts or shelves if you’re wiring multiple channels.
3. Connect to the audio system: Route the receiver outputs to your mixer, audio interface, or PA system using the appropriate cables (XLR or 1/4" TRS as required). Ensure gain staging is set to avoid clipping while maintaining clear level across channels.
4. Power up and configure: Connect power supplies to the receivers and turn on the transmitters. If IR sync is available, use it to quickly synchronize frequency settings between each transmitter and its corresponding receiver. In environments with many channels, perform a quick scan to assign clean, non-overlapping frequencies.
5. Test and calibrate: Perform a channel-by-channel audio check. Validate the presence of a stable RF signal, confirm audio levels are balanced, and adjust transmitter gain to prevent distortion or noise. Conduct a brief room test with all participants to ensure intelligibility and coverage throughout the space.
6. Secure and document your setup: Label each channel, store spare batteries and accessories, and maintain a simple log of your frequency assignments for future events. Regularly inspect antennas, connectors, and batteries to ensure ongoing reliability.
