The Sennheiser EW-DX TS-3-PIN-(Q1-9) is a professional digital wireless table stand transmitter designed for the EW-DX series, operating in the Q1-9 frequency band (470 to 550 MHz). This specialized transmitter integrates a locking 3-pin XLR connector, allowing it to accept any standard professional microphone with an XLR output, such as a gooseneck, boundary, or handheld dynamic/condenser microphone, making it a versatile wireless base for conference systems, panel discussions, lecterns, and installed sound applications. The unit transforms a traditional wired microphone setup into a high-performance digital wireless link, combining the audio quality and choice of a premium wired microphone with the freedom and reliability of Sennheiser's latest digital wireless technology. Its primary design eliminates the clutter and trip hazard of cables while maintaining full compatibility with existing microphone inventories.

The transmitter is built into a weighted, low-profile base that provides stability on a tabletop or lectern. It employs Sennheiser's advanced digital transmission protocol, featuring Adaptive Frequency Hopping Spread Spectrum (AFHSS) which continuously scans the RF environment and dynamically switches frequencies to avoid interference, ensuring a robust and dropout-free connection. The system operates with ultra-low latency (under 2 ms) and transmits 24-bit/48 kHz digital audio, preserving the full dynamic range and sonic integrity of the source microphone. The transmitter includes a high-resolution OLED display that shows critical information such as frequency, battery status, audio input level, and gain settings, while physical controls allow for local adjustment of parameters like gain and channel selection.

Power is supplied by a rechargeable BA 70 lithium-ion battery pack, offering extended operational time and compatibility with Sennheiser's networked charging ecosystem (e.g., CHG 70N) for centralized management and monitoring via Control Cockpit software. The inclusion of a 3-pin XLR connector with a locking mechanism ensures a secure connection to the microphone, preventing accidental disconnection. This model is supplied without a microphone, providing maximum flexibility for system designers to pair it with the optimal microphone for the application, be it a highly directional gooseneck for council chambers or a wide-pattern boundary microphone for conference tables. The EW-DX TS-3-PIN transmitter represents a significant advancement in wireless connectivity for fixed and semi-fixed speaking applications, delivering studio-grade audio quality, unparalleled RF reliability, and seamless integration into professional audio systems.
