Sennheiser I40-L ME36 Lobar Gooseneck System (40cm, Flange + Shockmount)

Product Overview

The Sennheiser I40-L is a complete IS series installed-sound gooseneck microphone system comprising the ME 36 supercardioid/lobar condenser capsule, a 40cm single-flex MZH gooseneck tube, MZT 30 flange mount, and MZS 31 shockmount. The 40cm gooseneck provides standard conference table height, while the ME 36 lobar capsule delivers the tightest directional pickup in the IS series for maximum inter-channel isolation. This system is the primary specification for formal government chambers, multi-seat legislative assemblies, and large boardrooms where strict isolation between adjacent microphone positions is required.

Product Description

The I40-L combines the maximum-isolation directional performance of the ME 36 lobar capsule with the practical 40cm gooseneck length that positions the capsule at standard speaking height for conference table use. The lobar polar pattern provides a very tight forward pickup, rejecting off-axis sound from adjacent delegates, audience areas, and room reflections more aggressively than either the ME 34 cardioid or ME 35 supercardioid. In multi-microphone automatic mixing systems and government assembly halls, this tight isolation prevents adjacent open microphones from picking up the same source, which degrades audio quality and complicates mixing. The ME 36 lobar pattern essentially limits each microphone to the speaker directly in front of it when properly positioned, enabling cleaner individual channel audio and better overall system performance. The single-flex 40cm gooseneck is repositionable for precise capsule aiming. The MZT 30 flange and MZS 31 shockmount provide clean surface installation with vibration isolation. The I40-L is one of the most commonly specified installed-sound gooseneck systems for high-end government and corporate conference facilities.

Key Features

• Complete Installation Kit — ME 36 lobar capsule, 40cm single-flex gooseneck, MZT 30 flange mount, and MZS 31 shockmount.
• Lobar Polar Pattern — Maximum inter-channel isolation for multi-seat conference and assembly room deployments.
• 40cm Gooseneck — Standard conference table height positioning for optimal capsule-to-mouth distance.
• Repositionable Single-Flex Tube — Precise capsule aiming for each delegate position.
• Flush Flange Installation — MZT 30 for clean surface integration into conference tables and podiums.
• Vibration Isolation — MZS 31 shockmount reduces surface vibration coupling to the capsule.

Typical Applications

Frequently Asked Questions

Why is the I40-L preferred for government and assembly rooms?

The ME 36 lobar pattern provides the tightest directional control in the IS series, allowing each microphone to focus on the directly adjacent speaker while rejecting sound from other positions. This is critical in large assembly rooms with many simultaneous open channels where cross-talk would compromise audio quality.

Is the I40-L compatible with automatic microphone mixing systems?

Yes. The tight lobar pattern of the ME 36 reduces the number of channels simultaneously picking up the same source, which improves the performance of automatic microphone mixing processors and reduces overall noise floor in multi-channel systems.

Can the I40-L capsule be replaced with a cardioid or supercardioid?

The ME 36 capsule can be physically replaced with an ME 34 or ME 35 capsule. However, for pre-configured cardioid or supercardioid 40cm gooseneck systems, the I40-C and I40-S systems are the appropriate choices.
