Portable Headset Station (Beltpack)

The BP1 portable headset station may be worn on the belt, hung on the wall by its sturdy belt-clip or set on top of a console where the soft plastic strips on its underside keep it in place. The matte black finish minimizes visibility.
 

The front panel contains controls for switching the microphone on and off, for controlling listening level, and for signaling. A long-life, extremely bright, 4-segment LED serves as the signal light. The back panel provides a 3-pin female XLR for connection to the system; a 3-pin male XLR for looping onwards to the next station; a 4-pin male XLR for connection of any standard communications headset; and a switch for choosing between dynamic or electret headset microphone.

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.
 

The top panel contains controls for switching the microphone on and off, for controlling listening level, and for signaling. They are easily identifiable by touch. A recessed, screwdriver-adjust control is provided for varying the level of the user's voice to be heard in his own earphone (Sidetone). A long-life, extremely bright, 4-segment LED serves as the signal light. The bottom panel provides a 3-pin female XLR for connection to the system; a 3-pin male XLR for looping onwards to the next station, and; a 4-pin male XLR for connection of any standard communications headset with a dynamic microphone.
