Product Overview +

Directional Audio Precision for Loud Venues

The Sennheiser SL Bodypack - MKE 40 KIT DW-4 is the ideal wireless solution for presenters and lecturers working in challenging acoustic environments. While most lavaliers are omnidirectional, the included MKE 40 features a cardioid pickup pattern. This directional focus is essential for "live" rooms where high gain-before-feedback is required, ensuring the speaker's voice is heard clearly over the sound reinforcement system without the risk of squealing or unwanted ambient noise.

The "Invisible" Sound Engineer

Part of the SpeechLine Digital Wireless family, this system is engineered to be a "hands-off" tool for busy professionals. It utilizes a bidirectional link to constantly monitor the RF environment, automatically switching to a clean channel if interference is detected. For the user, this means no more worrying about frequency groups or channel settings—the system handles the technical complexities in the background so you can focus on your delivery.

Scalable and IT-Ready

Designed with modern institutions in mind, the SL Bodypack - MKE 40 KIT can be managed as a networked asset. A/V and IT teams can use the Control Cockpit software to get a global overview of all units, checking battery health and reception quality from a central office. The bodypack’s integrated charging contacts allow for seamless workflow using the optional CHG 2 dock, while the secure AES-256 encryption ensures that private discussions remain confidential.

Reliable Performance for Regional Markets

Trusted by top-tier universities, corporate offices, and government facilities across Pakistan, the UAE, and Africa, the SL Bodypack - MKE 40 KIT DW-4 is built for 24/7 durability. Whether it is used for a high-stakes board meeting or a full day of academic lectures, the combination of a high-resolution cardioid mic and a robust digital link makes it a future-proof investment. For professionals seeking a dependable wireless lapel system that prioritizes clarity and feedback rejection, the Sennheiser MKE 40 Kit is the definitive choice.
