Description

The HD 300 PROtect adds Sennheiser’s patented ActiveGard™ technology, for advanced protection from peak levels above 110 dB. With ActiveGard™, disruptive or harmful peaks are brought down to a safe level, preserving clarity and control at all times. The HD 300 PROtect satisfies European EC noise directives on industrial safety and noise control while safeguarding hearing for all production staff, even in the event of big surprises.

Key Features:

  • Monitoring sound that always cuts through – for live stages and studio work
  • Maximum ambient noise attenuation and shielding
  • High-resolution acoustic system with high level of wearing comfort
  • Foldable earcup design

Reduction of Structure-Born Noise

  • Vibrations transferred along the cable are minimized by an innovative mechanical solution (short coiled section) of the cables of our modular cable system (Cable 26-II series).

Nameplates for Customization

  • The HD 300 PRO Series headphones can be customized with a company logo or user name.
  • Minimum order quantity for customization is 10 pcs; contact your Area Sales Manager for a price quote.

ActiveGard™

  • Only available on the HD 300 PROtect (Item # 506898) model.
  • Patented sound compression system consisting of a sophisticated electrical circuit incorporated into analogue headsets.
  • Utilizes a compression technology to remove the energy from an excessive incoming signal transmitted through the communication system, leaving the signal free of distortion.
  • Can be compared to an automatic and fast-working “intelligent” volume control. If an incoming signal rises to a level that is harmful to your hearing, it is instantly “turned down” to a lower, more comfortable level.
  • When the incoming signal returns to safe levels, ActiveGard™ reverts to its stand-by surveillance mode and volume is restored to its original level.
