The DMH9000 is not an intercom headset, but a broadcast version. It is equipped with a highly directional condenser microphone requiring DIN standard phantom voltage. That, in combination with its durability, lack of exposed wiring, and high noise-excluding ear muffs make it ideal for sports broadcasting and outdoor applications. It is fitted with standard broadcast connectors – a 3-pin male XLR for the microphone and a ¼” T/R/S phone plug for the earspeakers, both Neutrik.
The DMH9000, with its low visual profile, was specifically designed with broadcast and studio applications in mind. Special attention has been given to acoustical and electrical isolation of the microphone from the earspeakers to minimize the incidence of cross-talk. The symmetrical hypercardioid studio quality condenser microphone was expressly developed for near-field use and combines excellent noise rejecting abilities with a wide, smooth frequency response. The near-field characteristics of the microphone capsule provide good noise rejection with out having it so close to the mouth as to obscure the wearers face. The optimal distance is 4 in.
A new windscreen helps to eliminate wind and breath noise. The microphone is balanced and requires ‘phantom power’ 12~48V. The microphone boom can be positioned on the left or right side and swings up and out of the way past a series of detents. As the boom is raised a gold plated microswitch turns the microphone noiselessly off. The earspeakers have a specially contoured and wideband width in combination with high sensitivity. Two types of ear cushions are available. For sports announcing and similarly noisy applications, dual chamber foam-filled cushions provide optimum noise exclusion. In studio or other musical applications the alternate style of ear cushions are designed to optimize fre quency response.
