Intercom Headset / Handset Station (Flush Mount, Multi-Circuit) The HS2 performs the same functions as as BP1 beltpack but is designed to be mounted in a U.S. standard 2-gang electrical box. In addition to the BP1's front panel controls for Mic On/Off, Volume, Sidetone and Signal, it has a recessed screwdriver adjust microphone sensitivity control to adjust to a headset with either a dynamic or electret microphone. The CALL button doubles as the signal light. HS2 connections are via a rear panel plug-in terminal strip. The mating connector is included. Performance:The HS2 provides the same facilities as our BP1 portable headset stations (beltpacks) but in a format suitable for flush mounting in a 2-gang electrical box. A version is also available (HS2M) which includes a rotary switch to connect the station to up to 4 different circuits, one-at-a-time. 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 front panel contains controls for switching the microphone on and off, for controlling listening level, for signaling, and for adjusting the mic level to accomodate both dynamic and electret headset microphones. A recessed, screw driver adjust control is provided for varying the level of the user's voice to be heard in his/her own earphone (Sidetone). The HS2 has a terminal strip on the rear and fits in a standard 2-gang electrical box. The mating plug is included. The headset or handset connects to the station via a front-panel 4-pin XLR connector. The Call button on the front panel lights whenever anyone on the same circuit presses their signal light button. Durability:The component board of the HS2s are mounted to a thick metal mounting plate. Long-life switches and controls are used. The XLR is genuine Neutrik Value:Simplicity of design and construction affords the use of high quality components while maintaining a favorable cost/benefit ratio. Compatibility:The HS2 may be used with most unbalanced 200W party-line intercom systems. Specifications: Power requirement: 24 ~ 30 VDC, 10mA quiescent 40mA max.
