DMH220 Communications Headsets 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

BP1 Beltpack The BP-1 portable headset station may be worn on the belt or hung on the wall by its sturdy belt-clip. Soft plastic strips on the underside help hold it in place when set on top of a console. The matte black finish minimizes visibility. Frequency response has been carefully shaped to optimize both intelligibility and long-term listening comfort. A mic limiter circuit reduces overload distortion. The high bridging impedance ensures that system and sidetone levels do not vary as other stations are switched in and out of the circuit.

MS-200 Master Station The MS-200 is a full featured main station combining an outboard power supply with the facilities to control two independent communications circuits. The MS-200 has two independent communications circuits (A & B). The operator may communicate with stations connected to either A or B, or both A and B by pressing the circuit On switches. The two circuits remain independent, and stations connected to one cannot speak to stations connected to the other. During rehearsals, or other activities where a single common communications circuit would be desirable, pressing the Link button will accomplish that. Each circuit also has its own combination signal lamp and switch- the switch when pressed will light all the signal lamps on that circuit.
