The dual-sided Sennheiser HMD 300 PRO-X4F is a closed-back, circumaural communications headset offering detailed, linear response, switchable ActiveGard hearing protection, and a detachable XLR 4-pin female cable. The headset features comfortable construction with split-headband padding to remove pressure from sensitive areas of the head.
With a frequency response of 60 Hz to 25 kHz, the headphones provide clear reproduction of audio, doing so while offering up to 32 dB of passive noise reduction. The headset utilizes a dynamic boom microphone with a hypercardioid polar pattern for tighter pickup and a voice-optimized frequency range of 80 Hz to 16 kHz.
The headband supporting the unit s earcups is rugged, bendable, and twistable, and the boom can be worn on either side of the headset. To preserve your hearing, the headset features a switchable noise-protection mode called ActiveGard that protects against sudden bursts of sound without interrupting the signal or inducing distortion.
The HMD 300 PRO-X4F sports a modular cable design to accommodate multiple pin-outs and configurations. The included XLR 4-pin female cable and each of the separately available compatible cables minimizes handling noise by incorporating a small series of coils that decouple the cable from the headset.
Advantages of ActiveGard Technology
- The incoming signal is compressed in one controlled operation
- ActiveGard detects an excessive signal and reacts by initiating a compression process that occurs in just a few millisecondsfaster than the human ear
- Due to the compression method, there is virtually no distortion of the signal
- In contrast to peak-clipping circuits, ActiveGard removes the dangerous energy from the signal by means of this compression technique
- The more powerful the incoming signal, the more powerfully the system compresses
- Unlike peak-clipping circuits, ActiveGard keeps the volume at a comfortable level, even if the incoming signal is a sound burst well in excess of the limit which is generally considered to be harmful to hearing
