  SMH210 / DMH220  Communications Headsets 

Acrobat Spec Sheet - - View the Spare Parts Guide

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 7.35 oz. the SMH210, and at 8.75oz the DMH220, are much lighter than their appearances suggest. The noise-canceling microphone is mounted on a flexible, steel reinforced boom which can be easily twisted into a comfortable position. The flexible headband is adjustable. The normal transducer configuration for use with Production Intercom and compatible headset intercom systems are 400ohm earspeakers and a 200ohm dynamic microphone. Electret microphones and lower impedance earspeakers for other applications are also available, and combinations of these transducers make up the various models. For use with Production Intercom and most headset communications systems the SMH210 and DMH220 are fitted with a 4-pin female XLR-type plug. For other appliations many different plugs are available.

Durability: Because these headsets have only one moving part, and the microphone boom is flexible rather than hinged, a remarkable degree of durability is achieved. The light-weight cable consists of a copper shield around steel reinforced conductors, and is virtually unbreakable under normal circumstances. 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 on repairs.

Value: Low initial cost (compared to other professional communications headsets of equivalent quality), combines with long working life and low cost of repairs to offer outstanding value.

Compatibility: 200 series headsets are compatible with Clear-Com® and all other popular headset intercom systems, as well as drive-thru restaurant systems, disk jockey systems and other applications.
