DPA Microphones MMB4266-OP-FS1-L 4266 CORE+ Omnidirectional Flex Mic (Beige)

Engineered for Consistent and Clear Speech in Any Setting

The DPA MMB4266-OP-FS1-L is a 110mm omnidirectional microphone boom crafted for use with the DPA 4266 headset and earset systems. Featuring DPA’s CORE+ amplifier technology, this boom captures speech with exceptional clarity and minimal distortion, even in high-SPL environments. Whether you're on stage, in the studio, or presenting on camera, this mic boom delivers accurate, natural sound while maintaining a discreet profile.

Designed for Flexibility and Left or Right Fit

This 110mm boom can be mounted on either the left or right side of the DPA headset frame, making it easy to adapt to the user's preferred configuration. The neutral beige color blends well with skin tones for unobtrusive use in professional broadcast, theater, or worship environments. The boom’s length offers optimal positioning near the mouth for intelligible audio capture without obstructing the performer’s face.

Omnidirectional Pickup Ensures Uniform Audio Capture

Equipped with a 5.4mm pre-polarized condenser capsule, this microphone boom features an omnidirectional polar pattern that picks up sound evenly from all angles. This allows the speaker to move naturally without experiencing volume fluctuations or tonal shifts, making it ideal for dynamic performers and active presenters who rely on consistent sound quality.

CORE+ Technology Minimizes Distortion at High Volumes

The integrated CORE+ amplifier reduces total harmonic distortion and improves dynamic range, making this mic boom capable of handling up to 136 dB SPL RMS and 139 dB SPL peak before distortion becomes noticeable. For louder applications, the mic remains clear up to 144 dB SPL with only 10% distortion. This wide dynamic range ensures your audio remains clean and intelligible at any speaking or vocal level.

Built for Harsh Environments with Durable Construction

With its IP58 certification, this microphone boom is engineered to resist dust and moisture. Its internal double-vent protection system keeps the sensitive capsule safe from sweat, humidity, and airborne particles, making it a dependable choice for long hours on stage or in demanding outdoor environments.

A Drop-In Replacement for DPA 4266 Headsets

Designed as a modular component, the MMB4266-OP-FS1-L replaces worn or damaged microphone booms on compatible DPA headsets or earsets without the need to purchase an entirely new system. This reduces downtime for performers and technicians while maintaining the integrity of your audio gear.

Ideal for Broadcast, Theater, and Presentation Applications

With low visual impact, premium sound quality, and professional-grade durability, the MMB4266-OP-FS1-L boom mic is a go-to solution for live sound professionals, AV technicians, and broadcast engineers. Whether you're capturing a speech, sermon, or stage dialogue, this mic boom ensures that every word comes through clearly and naturally.
