Description

The Sennheiser SpeechLine Digital Wireless SL Bodypack DW-4-US is a purpose-built wireless transmitter designed for clear, reliable speech transmission in corporate, educational, and presentation environments. Compact and lightweight, this bodypack offers a digital 1.9 GHz wireless connection, delivering excellent audio clarity and up to 15 hours of operating time on a single charge with the included BA 30 rechargeable battery pack. Whether used in lectures, conferences, or meetings, it provides automatic frequency and interference management, allowing seamless setup without requiring manual configuration. It’s also compatible with a wide range of Sennheiser lavalier and headset microphones, such as the SL Headmic 1 or MKE 1 (sold separately), giving users flexibility based on their preferred mic style.

The SL Bodypack DW-4-US stands out with its simple and intuitive interface, including a non-backlit LCD display that shows essential information like battery status, signal strength, and link name. A lockable 3.5 mm mini-jack input ensures a secure connection for microphones, and a convenient mute slider makes it easy to control audio during use. It also features 256-bit AES encryption for secure wireless communication, and it’s fully compatible with Sennheiser’s Control Cockpit software for remote monitoring and configuration of connected devices.
