Sennheiser i40-C Gooseneck Microphone System
The i40-C is a desktop gooseneck microphone system built around the Sennheiser ME 34 cardioid condenser capsule and mounted for permanent installation. The cardioid pattern keeps a single speaker forward and turns down the room behind the mic, making it a natural fit for boardrooms, lecterns, courtrooms, and worship spaces where the voice has to feed a PA cleanly.
The ME 34 head sits on an MZH 3040 gooseneck that drops into an MZT30 XLR table mount with an MZS31 shock mount to keep desk thumps and vibration out of the signal. The capsule runs on 12 to 48V phantom power to a standard 3-pin XLR output. The system ships with the ME 34 capsule and windscreen, the MZH 3040 gooseneck, the MZT30 table mount, and the MZS31 shock mount.
