Sennheiser EW-D SK Digital Bodypack Transmitter (S1-7)

Reliable wireless connection for stage and presentations with the Sennheiser EW-D SK Digital Bodypack Transmitter (S1-7)

The professional transmission of instruments or speech on stage requires an absolutely stable wireless connection that does not drop out even in a dense radio environment. Conventional systems often lead to disruptive noise or complicated frequency searches, which costs valuable time during live performances. The Sennheiser EW-D SK Digital Bodypack Transmitter (S1-7) offers a well-thought-out and fail-safe solution that combines first-class signal quality with easy handling. This digital UHF bodypack transmitter operates in the professional S1-7 frequency range from 606.200 to 662.000 MHz and can be used flexibly for vocals, presentations, or instrument recording. Benefit from clear signal transmission and stress-free setup so that you can focus entirely on your performance. 

Your benefits at a glance

• Stable UHF transmission in the S1-7 range: Professional frequency range from 606.2 to 662.0 MHz for a reliable wireless connection with a long range.
• Compact all-metal housing: The robust bodypack transmitter is optimally designed for the high demands of daily stage use.
• App-based frequency management: The Smart Assist app enables automated setup and clear control without nested device menus.
• Outstanding dynamic range: A dynamic range of 134 dB ensures that even fine details are captured without distortion or signal noise.

First-class sound fidelity and minimal latency for demanding performances

The digital UHF system delivers an audio signal quality that significantly outperforms classic analog wireless connections. Thanks to the high-resolution 24-bit processing and the wide audio frequency response from 20 Hz to 20 kHz, the input signal is transmitted faithfully and unaltered. With a dynamic range of 134 dB, the transmitter effortlessly handles both extremely quiet passages and loud signal peaks from instruments without the signal distorting or getting lost in the noise. The very low system latency of just 1.9 ms guarantees a direct and natural listening experience for the performing artist on stage. This keeps the sound transparent, dynamic, and absolutely immediate at all times.

Flexible frequency usage and high scalability in the UHF band

The system is characterized by an even distribution of transmission frequencies, which effectively eliminates intermodulation interference. Within the switching bandwidth of 56 MHz, up to 2,240 selectable frequencies are available, allowing for larger multi-channel setups for panel discussions or events. The transmitter has a range of up to 100 meters in an unobstructed environment, offering sufficient freedom of movement on larger stages. Thanks to this scalability, the wireless connection easily adapts to the requirements of your events and productions.

Convenient operation via the Smart Assist app and long battery life

Thanks to the mobile Smart Assist app, even beginners with no prior experience can set up the wireless connection in no time. An intelligent algorithm handles the automated frequency selection and the synchronization of the devices via Bluetooth Low Energy, minimizing incorrect settings or frequency overlaps. For power supply, either two conventional AA batteries for up to 8 hours of operation or an optionally available lithium-ion battery pack can be used, which extends the operating time to up to 12 hours. A programmable mute button directly on the transmitter also allows for quick and easy muting of the audio signal during a break.
