Sennheiser's SpeechLine Digital Wireless SL Bodypack DW-4-US is a speech-optimized SL series wireless transmitter. It can be combined with an optional wireless receiver and microphone for meetings, lectures, conference presentations and applications where every word counts. It is also compatible with all Sennheiser microphones such as the SL Headmic 1 or MKE 1 (sold separately).
Two-way communication between the
transmitter and receiver and automatic frequency and interference control for easy and reliable use means the SL bodypack is maintenance-free. An LCD screen provides the connection name, battery status and reception quality, and an easily accessible negative slider makes the microphone very easy to use.
In addition, the SL bodypack comes with a BA 30 rechargeable battery with an external charger for easy charging via the CHG 2 and USB sockets. Offer up to 15 hours of work at full cost. Finally, the Sennheiser Control Cockpit software (download) provides easy operation, control and monitoring of the SpeechLine digital wireless system. It provides an overview of all network-enabled devices, displays all status information and makes configuration a breeze.
