Engineered for Clear and Consistent Voice Capture

The DPA MMB4266-OP-CS1-M is a replacement omnidirectional microphone boom designed for use with DPA’s 4266 headset and earset systems. Measuring 90mm in length and finished in a discreet brown color, this boom provides professional-grade voice capture for broadcast, theater, live presentations, and worship environments. With its CORE+ amplifier technology, it delivers high-fidelity audio that retains natural tonality, even in dynamic speech applications.

Optimized for Comfortable and Secure Use

This boom arm is designed to pair seamlessly with left- or right-mount DPA headset frames, offering flexible placement depending on the user’s needs. Its small profile ensures minimal visual distraction on stage or on camera. The 90mm boom length is ideal for close-mic speech applications where tight pickup and minimal movement are critical.

Omnidirectional Capsule Captures Natural Sound

The 5.4mm electret condenser capsule utilizes an omnidirectional polar pattern, allowing it to capture sound evenly from all directions. This design is perfect for performers or speakers who move their heads while talking, ensuring consistent sound levels without a drop-off in clarity or tone. The wide 20 Hz to 20 kHz frequency response ensures speech intelligibility and full-range vocal reproduction.

CORE+ Technology for Low Distortion and Wide Dynamic Range

Built with DPA’s advanced CORE+ amplifier circuit, this mic boom significantly reduces distortion across the dynamic range. It can handle high sound pressure levels up to 144 dB SPL peak, ensuring that even loud vocalists or dynamic speakers remain distortion-free. The result is audio that stays clean and transparent in all performance scenarios.

Durable and Moisture-Resistant for Demanding Conditions

Designed for real-world use, the 4266 boom features a moisture- and dust-resistant construction with an IP58 rating. This makes it a reliable option for high-humidity environments, long performance hours, and the demands of professional production. The boom is also built to withstand repeated reconfiguration and daily wear in mobile or stage environments.

Modular Compatibility with DPA Headsets and Accessories

As part of DPA’s modular system, this boom can be easily swapped or paired with other DPA headset components. That means users can quickly replace the boom without having to purchase an entirely new headset system, reducing downtime and long-term cost of ownership.

Ideal for Discreet On-Stage or Broadcast Applications

With its compact design, neutral brown color, and high-performance specifications, the MMB4266-OP-CS1-M is ideal for performers and presenters seeking low-visibility miking without sacrificing sound quality. Whether used for corporate presentations, live theater, or broadcast talent, this mic boom ensures reliable, natural audio reproduction.
