The Sennheiser EW-DX TS 5-PIN (S1-10, article 700193) is a digital tablestand transmitter from the Evolution Wireless Digital series, designed for boardrooms, council chambers, lecterns and conference tables where a gooseneck microphone needs to be wireless. It has a 5-pin XLR socket on top for a gooseneck such as Sennheiser's MEG 14-40 L-II B (sold separately), a metal housing and a programmable mute switch. The transmitter works in the 606.2 - 693.8 MHz range with EW-DX receivers such as the EM 2 and EM 4, with 1.9 ms latency, 20 Hz - 20 kHz frequency response and 134 dB dynamic range. Power comes from the included BA 40 lithium-ion battery (3.6 V, 2.2 Ah), which gives around 10 hours of use and can be charged inductively on the CHG 2W charger or via USB. RF output is 10 mW ERP, and it operates from -10 to +50 C. It allows tidy, cable-free table layouts that can be re-arranged quickly between meetings.
