Pro Intercom BP1SL Switchable Circuit A or B Portable Headset Station

Pro Intercom BP1SL Switchable Circuit A or B Portable Headset Station The BP1SL is a modified BP1 that can switch between two circuits. It can communicate only with one circuit at a time. It does have a unique feature allowing both signal lamps to work at all times. If you are using circuit A and someone is trying to contact you from circuit B, the circuit B signal lamp will light, and vice/versa. The circuit connection XLRs on the back are both female, so you cannot loop-through to the next station as you can on a BP1, without the use of a simple Y-cable or SB1 Splitter box. Key Features The BP1SL is designed to be connected to two different circuits, but may only communicate with one at a time. When the user is connected to either circuit, the signal lamp for the other is still active. The BP1SL portable head set station may be worn on the belt or hung on the wall by its sturdy belt-clip. Ribbed, extruded aluminum case, glass-filled nylon end bezels, internal support system for the PC board. Technical Specifications Power requirement 24~30VDC, 10mA quiescent, 30mA max.
