Sennheiser SL Headmic Set DW SpeechLine Digital Wireless System

The SL Headmic Set bundles Sennheiser's SL Bodypack transmitter with a headworn microphone and an SL Rack Receiver, built for presenters, instructors, and tour guides who need both hands free while staying consistently on-mic. It runs on the SpeechLine Digital Wireless platform, aimed at rooms where speech intelligibility matters more than anything else.

Bidirectional communication between the bodypack and rack receiver lets the operator adjust the transmitter remotely, and automatic frequency and interference management sets up the RF link without manual coordination. The bodypack runs in the 1920-1930 MHz DECT band on a rechargeable Li-Ion pack rated for up to 15 hours, with AES 256 encryption protecting the link end to end.
