Pro Intercom Belt Pack Single Circuit with Dynamic Mic BP1

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.

FEATURES

• Single channel portable headset station
• Call button with signal light
• Adjustable volume and sidetone levels

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 female XLR for connection to the system; a 3-pin male XLR for looping on wards 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 in telligibility 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 BP1 is plug-in compatible with Clear-Com and other popular headset intercom systems.
