SENNHEISER 540370 SPARE MICROPHONE BOOM ARM ASSEMBLY For HMD46 headset, c/w microphone

These broadcast headsets are said to offer ‘clear communication, even in high-volume backstage environments’. The closed circumaural design provides a frequency response of 60Hz to 25kHz whilst Sennheiser’s ‘ActiveGard’ limiting technology prevents sudden bursts of high level audio. The hypercardioid, dynamic boom microphone can rotated such that it can be worn on either left or right side, while the split headband alleviates pressure for long-term use.

Designed primarily for outside broadcasters, HMD 26 features a hypercardioid, dynamic microphone with supra-aural, closed-back earphones. Commonly used for outdoor TV or radio applications, the headset features Sennheiser’s ActiveGard limiting technology with three switchable attenuation settings to prioritize isolation, noise reduction, and hearing protection. The shock-mounted microphone capsule has a frequency response of 40Hz - 20kHz and delivers ‘excellent acoustic performance’ whilst absorbing structure-born noise.

HMD 27 has been tailored for use for commentators, audio engineers, or those who require ‘the highest levels of audio performance’. The headset has a closed, circumaural earpiece design that features Sennheiser’s ActiveGard limiting technology with three-step switchable attenuation. This inbuilt limiting technology protects the user from sharp spikes in audio volume. The dynamic microphone capsule has a hypercardioid pickup pattern and a frequency response of 40Hz to 18kHz. The headset’s lightweight build, soft earpads, and two-piece headband provide a more comfortable wear for prolonged periods of use. This headset is supplied without cable and therefore one of the optional cables listed is required for use.

Headphone frequency response: 4Hz - 21kHz. SPL: 102dB, characteristic; 125dB, maximum; 95/110dB, ActiveGard. Impedance: 64ohm. Contact pressure: 3.6N. Microphone type: BMD 434. Transducer principle: Dynamic. Directivity: Hypercardioid. Impedance: 300ohms. Sensitivity: 0.5mV/Pa, 1kHz. Frequency response: 40Hz - 18kHz. Weight (without cable): 240g

HMDC 27 has the same feature set as HMD 27, however HMDC has a greater impedance of 130ohms, features ActiveGard limiting technology for protection from noise peaks greater than 110dB, and switchable NoiseGard technology that increases intelligibility and reduces noise by an additional 15dB for operation in the noisiest environments.

This headset is supplied without cable and therefore one of the optional cables listed is required for use.

Headphone frequency response: 4Hz - 21kHz. SPL: 105dB, characteristic; 125dB, maximum; 110dB, ActiveGard. Impedance: 130ohm. Contact pressure: 3.6N. Microphone type: BMD 434.
