The Sennheiser EW-DX TS 3-pin (S1-10) is a wireless tablestand transmitter for the Evolution Wireless Digital EW-DX system, providing a sturdy, weighted desktop base for a Sennheiser 3-pin XLR gooseneck microphone without LED ring (gooseneck sold separately). It is designed for boardrooms, lecture halls, council chambers and panel discussions where speakers stay seated. A programmable mute switch lets each delegate mute themselves, and the unit runs about 10 hours on the included BA 40 lithium-ion battery, charging by USB or inductively on the optional CHG 2W charger. Like other EW-DX transmitters it offers 134 dB dynamic range, 20 Hz to 20 kHz response and 1.9 ms latency, and pairs with EW-DX receivers. This S1-10 variant covers 606.2 to 693.8 MHz. It weighs about 650 g. In the box: EW-DX TS 3-pin tablestand transmitter, BA 40 rechargeable battery, quick guide and safety guide.
