Description
The headphones are dimensioned for high maximum SPL. HMDC 26 provides high wearing comfort in combination with a good noise attenuation. The HMDC 26 for Broadcast is equipped with Peak Level-Protection which protects the user from volume peaks. The dynamic microphone with hyper-cardioid characteristic satisfies with perfect broadcast sound up to 16 kHz. It is mainly designed for applications in noisy environments. Another important feature is the less sensitivity against structure-born sound. The gooseneck microphone can be used either on left or right-hand side. The microphone boom allows an individual adjustment at the right position.
