Sennheiser SL Lavalier Set DW SpeechLine Digital Wireless System

The SL Lavalier Set bundles Sennheiser's SL Bodypack transmitter with a clip-on lavalier microphone and an SL Rack Receiver, giving a facility a complete presentation-mic system out of one box rather than assembling the pieces separately. It is built for the SpeechLine Digital Wireless platform, which targets rooms where every word from a presenter or panelist needs to be heard clearly.

Bidirectional communication between the bodypack and rack receiver means the operator can adjust the transmitter's settings from the receiver without walking over to the presenter, 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.
