Production Intercom BP-1

Production Intercom's BP-1 portable headset station's frequency response has been shaped to optimize 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 BP-1's top panel contains an on/off switch, volume control dial, and a signaling button.  A recessed, screwdriver-adjustable control is provided for varying the level of the user’s voice to be heard in his or her own earphone.  The bottom panel features 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.
