The Sennheiser EW-DX TS-3-PIN-(R1-9) is a professional digital tabletop/wireless stand transmitter designed to integrate high-quality wired microphones into a flexible, cable-free digital wireless system. Operating in the R1-9 frequency range (520 to 607 MHz), this transmitter is engineered for applications such as conference tables, lecterns, panel discussions, and musical performances where a stationary, aesthetically clean setup is required. It functions by replacing the standard XLR cable of any professional microphone with a 3-pin XLR female connector, effectively converting the mic into a digital wireless source. This allows presenters, vocalists, or instrumentalists to use their preferred, potentially high-value, wired microphones—such as large-diaphragm condensers for broadcast or dynamic microphones for live sound—without the physical constraint and tripping hazard of a cable, while maintaining the microphone's inherent sonic characteristics.

The unit is housed in a low-profile, weighted base that provides stability on a tabletop or when mounted on a microphone stand via its integrated 1/4-inch thread. It incorporates Sennheiser's advanced digital transmission technology, which delivers 24-bit/48 kHz audio quality with a wide dynamic range, extremely low latency, and robust immunity to interference. Features like automatic frequency scanning and one-touch synchronization with a compatible EW-DX receiver simplify setup and ensure a reliable link. The transmitter includes essential controls and a clear OLED display for monitoring parameters such as selected frequency, battery status, audio input level, and RF signal strength, empowering the user or technician to verify optimal performance at the source.

Built for reliability in continuous-use environments, the TS-3-PIN transmitter offers flexible powering options, including an external DC power supply for permanent installations or rechargeable battery operation for temporary setups. Its design includes a locking XLR connector to prevent accidental disconnection and intelligent features like a pilot tone for secure muting and remote gain control capability from the paired receiver. By bridging the gap between the world of exquisite wired microphones and the convenience of modern wireless systems, this table stand transmitter provides system integrators and audio professionals with a powerful tool to create clean, professional, and high-fidelity audio capture points for speaking and musical applications in both fixed and mobile scenarios.
