The SpeechLine Digital Wireless SL Bodypack DW-4-US from Sennheiser is an SL Series wireless transmitter optimized for speech. It can be used when paired with an optional wireless receiver and microphone in applications for meetings, lectures, conferences presentations where every word matters. In addition, it is compatible with all Sennheiser microphones such as the SL Headmic 1 or MKE 1 (sold separately).

Featuring bi-directional communication between transmitter and receiver, the automatic frequency and interference management allows for convenient and reliable operation, which means the SL bodypack requires no settings to be adjusted. The LC display provides the link name, battery status and reception quality, and the easy-to-access mute-slider makes the use of the microphone very convenient.

Furthermore, the SL bodypack comes with a rechargeable BA 30 accupack that is built with external charging contacts – for easy charging with the CHG 2 and a USB socket. It provides up to 15 hours of operating time on a full charge. Finally, Sennheiser Control Cockpit software (download) offers easy handling, control, and maintenance for the SpeechLine Digital Wireless System. It provides a global overview of all network-enabled devices, shows all status information, and makes setting adjustments very easy.

The Sennheiser MKE1 Miniature Lavalier Microphone is their smallest, professional lavalier microphone to date. Measuring just 3.5mm (0.13") in diameter, the MKE1 is well suited for placement in hair, the body, clothing, accessories, props, etc.

Audio signal is reproduced transparently, while maximum intelligibility of speech and vocals is achieved with its omnidirectional polar pattern and wide frequency response.

The Kevlar reinforced cable is rugged and minimizes surface noise. The MKE1's moisture resistant enclosure protects against damage caused by moisture, making it well suited for actors, performers and broadcast applications.

The SpeechLine Digital Wireless SL Rack Receiver DW-4-US from Sennheiser is an easy-to-integrate wireless receiver for the SpeechLine Digital Wireless System. It features an OLED display for easy setup and operation and can be used when paired with a wireless transmitter and microphone (sold separately) for applications such as lectures, meetings, and more.

With secure 256-bit AES encryption, the receiver has bi-directional communication, which allows all settings from the mobile transmitter to be adjusted from the receiver. In addition, the automatic frequency and interference management provides convenient and reliable operation, thanks to the easy-to-handle pairing process.

Finally, via network integration all settings and statuses are accessible from AMX/Crestron media-control protocols and the dedicated Sennheiser Control Cockpit software. The antennas can be either back or front mounted. A power supply is also included.

The BA 30 from Sennheiser is a rechargeable battery pack for the evolution wireless SK D1 or AVX Bodypack Transmitter (sold separately). It can be used to replace the two AA size batteries that power the transmitter-unit. The BA 30 uses a lithium-ion 3.7V rechargeable battery.
