CLOSED-BACK CIRCUMAURAL BROADCAST HEADSET FOR BACKSTAGE COMMUNICATION, SWITCHABLE ACTIVEGARD© LIMITI
- UM : EA
The HMD 300 broadcast headsets offer clear communication, even in high-volume backstage environments. A closed circumaural design offers a frequency response of 60 Hz to 25 kHz for clear audio reproduction, while ActiveGard© limiting technology intelligently shields against sudden audio bursts. A dynamic boom microphone combines a super-cardioid polar pattern and structure-borne noise decoupling with the flexibility to be worn on either side, while a split headband alleviates pressure for long-term use.
Features:
- Dual-sided earcup design ideal for noise isolation and enhanced immersion applications
- Comfortable, single-sided design ideal for dynamic communication environments
- Dynamic super-cardioid microphone for clear communication in noisy environments
- Switchable ActiveGard© limiting technology for protection of noise peaks <110 dB
- Switchable microphone boom for left- or right-side configuration
- Linear sound reproduction for optimized for speech intelligibility
- Comfortable padding allows for extended use in long wearing sessions
- Closed passive earcup construction for superior ambient noise attenuation in loud environments
- Foldable earcup design for easy, space-saving storage
