Sennheiser MAT 153-S Microphone Table Stand

The MAT 153-S is the 5-pin XLR table base in the SpeechLine Wired range, carrying both the microphone signal and the logic that a control system needs to see who is talking. The -S suffix is the push-to-talk switch built into the base.

It reports a high-level output above 2.4 V, weighs 1.2 kg so it stays put on a table, and is finished in black.
