Sennheiser I40-C ME34 Cardioid Gooseneck System (40cm, Flange + Shockmount)

Product Overview

The Sennheiser I40-C is a complete IS series installed-sound gooseneck microphone system comprising the ME 34 cardioid condenser capsule, a 40cm single-flex MZH gooseneck tube, MZT 30 flange mount, and MZS 31 shockmount. The 40cm gooseneck provides greater height and reach than the 15cm I15-C, making it appropriate for larger conference tables, delegate positions, and podium installations where the microphone needs to reach closer to the speaker's mouth from a surface-mounted position. The ME 34 cardioid pattern provides directional pickup with rear rejection for effective speech capture.

Product Description

The I40-C is the standard-length cardioid IS series gooseneck system from Sennheiser, providing a 40cm single-flex gooseneck that allows the ME 34 cardioid capsule to be positioned at a practical speaking height above the installation surface. In conference room installations, the 40cm gooseneck is one of the most commonly specified lengths — it provides sufficient height above the table surface to place the capsule at an appropriate distance from the speaker's mouth for optimal intelligibility without being excessively tall or visually dominant. The single-flex gooseneck tube is repositionable, allowing the capsule to be aimed precisely at the speaker's mouth when the microphone is deployed. The ME 34 cardioid pattern maintains forward directional pickup, reducing pickup of audience noise and adjacent microphone positions while supporting acoustic feedback control in sound-reinforced systems. The MZT 30 flange mount enables clean flush installation into conference table or podium surfaces, and the MZS 31 shockmount reduces low-frequency vibration from the surface. The I40-C is identified by "I" for installed, "40" for 40cm gooseneck, and "C" for cardioid.

Frequently Asked Questions

What is the difference between the I15-C and I40-C?

The primary difference is gooseneck length — the I15-C uses a 15cm tube for compact low-profile installations, while the I40-C uses a 40cm tube for positions where a taller microphone height above the table is needed. Both use the same ME 34 cardioid capsule, MZT 30 flange, and MZS 31 shockmount.

Is the 40cm gooseneck repositionable?

Yes. The single-flex MZH gooseneck tube is flexible and can be bent to position the capsule at different angles and heights to optimise placement relative to the speaker's mouth.

Is the I40-C available with a different capsule?

Yes. The I40-L (lobar) and I40-S (supercardioid) systems use the same 40cm gooseneck with ME 36 and ME 35 capsules respectively for different directional requirements.
