Features & Specifications
Product Overview +
High-Performance Collaborative System Type
The Sennheiser SL Bodypack - SL Headmic 1 KIT DW-4 is a professional digital wireless headworn system designed to solve the challenge of restrictive microphones in modern speaking environments. By pairing the intelligent SpeechLine transmitter with the unobtrusive SL Headmic 1, presenters gain total freedom of movement. Whether utilized for a university lecture hall or a high-profile corporate briefing, this kit provides the legendary Sennheiser clarity and mechanical reliability required for elite-level voice reinforcement.
Professional Production Connection Type
Equipped with a locking 3.5mm TRS connection type, the SL Bodypack provides a fail-safe link for the MKE 1 capsule. This technical architecture is a critical requirement for production teams in Pakistan, the UAE, and across Africa who operate in crowded RF environments. The 1.9 GHz digital transmission ensures that high-definition 1080p and 4K live streams are supported by transparent audio, effectively bypassing the congestion of traditional UHF bands.
Specialized Ergonomic Engineering
The SL Headmic 1 KIT solves the problem of "presenter discomfort" through its extremely lightweight metal frame and adjustable neckband. The integrated mute-slider on the bodypack allows for convenient local control, while the Sennheiser Control Cockpit software provides a global overview of all network-enabled devices. With its included sleek soft case designed to hold both the mic and transmitter, this wireless kit provides the technical reliability and structural simplicity required for professional audio captures in any high-stakes business or academic setting.
