Pro Intercom DMH920 Super-Rugged Double-Ear Intercom Head

Performance:
Exceptionally high quality transducers provide wide smooth frequency response, reducing the onset of ear fatigue for those who must spend many hours wearing headsets. Deep, comfortable ear cushions have excellent external noise exclusion characteristics, and are washable with ordinary dish washing detergent. At 10.8oz (.306kg), including the cable and XLR, the SMH910 is much lighter than its appearance suggests. Even the dual muff version, DMH920, weighs in at only 15.3oz (.435kg). The noise-canceling microphone is mounted on a flexible, steel reinforced boom which can be bent for optimum positioning. The boom swings up out of the way when required and shuts the microphone off at the top of the swing. The boom can be reversed for use on the right side. The flexible headband is adjustable. The normal transducer configuration for use with Production Intercom and compatible headset intercom systems is 400W earspeaker(s) and a 200W dynamic microphone. Electret microphones and both 50 and 100W earspeakers are also available for various other applications. The standard version comes with a 4-pin female XLR-type plug but other configurations are available. The microphone in the standard version is wired unbalanced but it can easily be balanced for audio or broadcast applications.

Durability:
All headsets are the most vulnerable to damage at the point where the boom connects with the ear cup. The ingenious way in which the boom swivels on the 900 series offers a whole new level of longevity. The internal switch, which mutes the microphone at the top of the boom's arc, is rated for millions of operations. The assembly screws are hidden to prevent tampering. These headsets are easily field repairable. Production Intercom maintains a full inventory of replacement parts at reasonable prices and provides fast turnaround if repairs ever become necessary.

Value:
These fully featured professional headsets are priced competitively with headsets offering lesser performance and greater fragility. These combine with long working life and low cost of repairs to offer outstanding value.
