The Sennheiser EW-D 835-S SET (R1-6) is a professional, fully digital wireless handheld system operating within a designated UHF frequency range (typically corresponding to a specific global region within the 470-694 MHz spectrum). This complete set integrates Sennheiser's acclaimed vocal microphone technology with a state-of-the-art digital wireless platform, offering superior audio clarity, robust RF performance, and advanced features for modern live sound and installed applications. The system includes a digital handheld transmitter with a fixed MM 835 dynamic cardioid capsule and a compact, feature-rich true-diversity receiver, providing an out-of-the-box solution for vocalists, presenters, and performers who demand reliable, high-quality wireless audio.

The handheld transmitter is constructed with a rugged metal body, housing the proven MM 835 capsule known for its smooth vocal reproduction and effective feedback rejection. The system's core innovation is its fully digital signal path; the analog microphone signal is converted to digital within the transmitter itself before being broadcast. This digital transmission provides inherent immunity to RF intermodulation distortion and other analog interference, ensuring stable operation even in spectrally crowded environments. The accompanying digital receiver features an intuitive color LCD display for monitoring vital parameters like RF signal strength, audio levels, and transmitter battery status. It also includes professional tools such as automatic frequency management, 128-bit AES encryption for secure transmission, and Ethernet connectivity for networking multiple systems and enabling remote control via software.

Designed for ease of use without compromising professional capability, the EW-D system offers automatic channel scanning and grouping for quick, interference-free setup. The digital architecture delivers audio with extremely low latency, preserving the natural feel of a live performance, and a wide dynamic range for transparent sound. The receiver provides both balanced XLR and unbalanced 6.3 mm jack outputs for seamless integration into any sound system. As a complete set, the Sennheiser EW-D 835-S (R1-6) represents a significant step forward in wireless technology, providing users with a future-proof, reliable, and sonically excellent digital wireless vocal system that combines trusted Sennheiser sound with the benefits of modern digital transmission.
