Sennheiser EW-DX MKE 2/835-S Combo Wireless Handheld and Lavalier Microphone System - R1-9

The Sennheiser 509329 is a wireless microphone package that gives you both a handheld mic for vocal work and a lavalier mic for discreet speech, all routed to a receiver designed for rack mounting and simultaneous two-channel operation. It arrives ready for conference rooms, lecture halls, houses of worship, and live stages where quick changeovers and dependable audio matter.

Setup stays simple. Power up the system and it automatically scans the room, chooses clear frequencies, and locks them in. With a 134 dB dynamic range, you will not need to hunt for the right gain setting; normal conversation, excited speech, and strong singing are all handled without clipping or background hiss. Latency sits at just 1.9 milliseconds, so what you see on stage matches what you hear in the speakers or on a video stream.

The link between transmitter and receiver reaches up to 328 feet, giving presenters freedom to move anywhere in a large auditorium or event space. AES-256 encryption keeps the signal private, a requirement for corporate meetings and broadcast work. Each transmitter runs up to 12 hours on the included rechargeable batteries, and the receiver’s Ethernet port connects to Sennheiser Control Cockpit software or the Smart Assist app for remote monitoring, firmware updates, and coordination of larger multi-room systems.

Because the handheld body accepts Sennheiser and Neumann capsules, engineers can swap in different voicings to match a singer or speaker. Add the network capability and you have a scalable backbone that integrates easily into existing sound installs or touring rigs.
