Sennheiser SL Bodypack - MKE 40 KIT Receiver

Product Overview

The Sennheiser SL Bodypack – MKE 40 KIT is a professional digital wireless system bundle combining the SpeechLine DW bodypack transmitter with the MKE 40 cardioid clip-on microphone for secure, high-quality wireless audio in presentation, conference, and AV installation environments. Operating over Sennheiser's SpeechLine DECT-based DW platform, it delivers up to 15 hours of battery life, 256-bit AES encryption, and automatic frequency and interference management for plug-and-play reliability. The included MKE 40 features a cardioid polar pattern with integral shock-mounting for clean, feedback-resistant speech pickup. Multiple DW frequency variants (DW-4, DW-5, DW-6, and base DW) are available to accommodate different DECT frequency slot requirements in your region or installation.

Product Description

Built as the ideal complement to the Sennheiser SL Multi-Channel Receiver DW, the SL Bodypack – MKE 40 KIT delivers enterprise-grade wireless audio performance for fixed AV installations, lecture halls, boardrooms, and live presentation environments. The SL Bodypack DW transmitter uses Sennheiser's SpeechLine DECT platform, which operates in the globally license-free 1.9 GHz DECT band — eliminating the RF congestion challenges common in crowded 2.4 GHz or VHF/UHF frequency ranges. Bi-directional communication between the bodypack and the SL receiver means setup is fully managed from the receiver side; no adjustments need to be made at the transmitter, simplifying multi-channel deployments and remote management. The transmitter's LC display shows the radio link name, battery charge level, and reception quality at a glance, and the easily accessible mute switch allows the presenter to silence the mic without assistance. The SL Bodypack DW uses a rechargeable lithium-ion battery pack with external charging contacts, allowing direct charging in compatible Sennheiser chargers, and also includes a USB socket for flexible charging via USB when a dedicated charger is not available. With up to 15 hours of operation per charge, it covers multiple presentation sessions without mid-event recharging. The MKE 40 clip-on microphone features a cardioid polar pattern with integral shock-mounting for natural speech reproduction and effective rejection of handling and mechanical noise. High gain before feedback makes it well suited for installation in rooms with distributed speaker systems. Secure 256-bit AES encryption ensures audio transmission is protected against interception in sensitive corporate or government environments.

Frequently Asked Questions

Q: What receiver is the SL Bodypack MKE 40 KIT designed to work with?

The SL Bodypack DW transmitter is designed as the ideal companion to the Sennheiser SL Multi-Channel Receiver DW. The bi-directional DECT communication means all configuration is managed from the receiver side, so no manual setup is required at the bodypack.

Q: What is the difference between the DW-4, DW-5, DW-6, and base DW variants?

These variants correspond to different DECT frequency slots used in different regions and installations. DW-4 is priced at $739, while DW-5, DW-6, and the base DW variant are priced at $629. Select the variant that matches your SL Multi-Channel Receiver DW and regional frequency requirements.

Q: Does the MKE 40 use a lavalier or clip-on design?

The MKE 40 is a clip-on microphone with a cardioid polar pattern and integral shock-mounting. It is designed to clip to a lapel, collar, or instrument and provides cardioid directionality for focused speech pickup and high gain before feedback — distinct from an omnidirectional lavalier.

Q: How long does the battery last and how is it charged?

The SL Bodypack DW provides up to 15 hours of operation on its built-in lithium-ion rechargeable battery pack. It can be charged via external charging contacts in compatible Sennheiser chargers, or via the built-in USB socket for flexible charging without a dedicated charger.

Q: Does the SpeechLine DW system require frequency coordination?

No. The SpeechLine DECT platform uses automatic frequency and interference management to select and maintain the best available channel automatically. This eliminates the need for manual RF coordination, simplifying multi-channel deployments.

Q: Is the audio transmission encrypted?

Yes. The SL Bodypack DW uses 256-bit AES encryption to secure all wireless audio transmissions, making it appropriate for sensitive corporate, government, and institutional environments.

Q: Does the presenter need technical assistance to mute the microphone?

No. The SL Bodypack DW includes an easily accessible mute switch that the presenter can operate directly, without requiring assistance from an audio technician.
