Sennheiser SL Bodypack DW SpeechLine Digital Wireless Transmitter
The SL Bodypack is the transmitter half of Sennheiser's SpeechLine Digital Wireless system, built for presentations and lectures where every word needs to land clearly. It runs in the 1920-1930 MHz DECT band with automatic frequency and interference management, and bidirectional communication with the SL Rack Receiver means the operator never has to walk over and adjust a setting on the bodypack itself.
A lockable 3.5mm connector accepts any SL-compatible lavalier or headworn microphone, and an LC display on the body shows link name, battery status, and reception quality at a glance. The rechargeable Li-Ion pack runs up to 15 hours, and AES 256 encryption keeps the RF link private. It ships as a bare bodypack for a facility that already owns microphones, or as a kit bundled with an SL Headmic 1, ME 2, MKE 2, MKE 40, or HS 2 microphone.
