Details

The BP1 portable head set station may be worn on the belt or hung on the wall by its sturdy belt-clip. Soft plastic strips on the under side help hold it in place when set on top of a con sole. The matte black finish minimizes visibility.
Frequency response has been care fully shaped to optimize both intelligibility and long-term listening comfort. A mic. limiter circuit reduces over load 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 (front) panel contains controls for switching the microphone on and off, for controlling listening level, and for signaling. They are easily identifiable by touch, in the dark. A recessed, screwdriver-adjust control is provided for varying the level of the user’s voice to be heard in his own ear phone (Sidetone). A long-life, extremely bright, 4-segment LED serves as the signal light. The back (bottom) panel provides a 3-pin fe male 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 head set; and a switch for choosing between dynamic or electret head set microphone.

The ribbed, extruded aluminum case; glass-filled nylon end bezels; internal support system for the PC board; best-quality XLR-type connectors, and recessed controls, all contribute to the outstanding ability of the BP1 to withstand rough usage.

The comparatively low price of the BP1 is made possible by the minimized assembly cost resulting from simplicity of design & construction. Simple construction also affords the use of higher quality components, and increases the ease (thus lowering the cost) of servicing.

The BP1 is plug-in compatible with Clear-Com® and other popular head set intercom systems
