OVERVIEW

Featuring Active Gard hearing protection.

Professional ears require not only crystal-clear, high-resolution sound, but also protection from unexpected peak levels. Here, the Active Gard system of the HD 300 PROtect is on the case. Instead of simply clipping peaks above 110 dB, the system adjusts the overall sound down to the maximum permitted volume – retaining all information and dynamics in the process. Other design elements like the maximum shielding of ambient noise and a sound pattern with clear intelligibility, differentiation or resolution also protect the user’s concentration. The ergonomic design guarantees that, even after hours of work, only one thing ‘carries weight’: the sound.

The patented Active Gard technology of the HD 300 PROtect does not simply switch off at peak levels above 110 dB but reduces signals that are too loud down to a safe level. Previously disruptive or harmful volumes remain distortion-free and clear, and control of the production is retained at all times. The HD 300 PROtect not only satisfies with the European EC noise directive on industrial safety and noise control, but also safeguards the hearing and presence of mind of all production staff, even in the event of big or small surprises.

The acoustics of the HD 300 PROtect are systematically tailored to the requirements of professional use. Its linear frequency response provides a neutral, high-resolution sound. With its highly sensitive transducers and precision diaphragms, the HD 300 PROtect achieves a phenomenal depth of detail which it reproduces – even at maximum volumes – in a crystal clear manner without distortions. For an ambient sound, we have recalculated the air volumes in front of the ear at a level, inspired by the HD 250 linear.

Professionals often wear headphones for several hours. The HD 300 PROtect is precisely designed for this purpose with its particularly soft, viscoelastic earpads – which also systematically filter out ambient noise – and finely balanced pressure distribution. Use it continuously with no discomfort.
