Description

The SL Lavalier Set DW-4-US R is a compact, professional wireless microphone system designed to deliver exceptional clarity and reliability for speeches, lectures, and presentations. At the heart of this set is the MKE 1 condenser lavalier microphone, Sennheiser’s smallest and most discreet lav mic, offering natural, full-bodied speech reproduction with minimal ambient noise pickup. Its unobtrusive profile makes it ideal for on-camera use and live settings where visual discretion is just as important as audio performance.

This Rackmount version (-R) includes a SL Bodypack DW transmitter, a SL Rack Receiver DW, and a BA 30 rechargeable battery with up to 15 hours of operation. The system transmits over the secure and interference-resistant 1920–1930 MHz frequency range and features 256-bit AES encryption for secure communication. Connectivity options include XLR 3M, dual RCA audio outs, and RJ45 network ports, making it easy to integrate into professional AV setups. With a dynamic range over 120 dB(A), sampling rate of 24-bit/48 kHz, and signal-to-noise ratio above 90 dB(A), this set ensures your voice is heard clearly and consistently. Designed for plug-and-play convenience, it also includes rackmount accessories or a case, depending on the version selected, making it a flexible solution for both permanent installations and mobile use.
