Audiocom® System Specifications
A udio Line Impedance:
300 ohm per channel—typically supplied by system Power Supply —
unless locally powered.
Station Bridging Impedance:
(Individual Stations) 10K ohms nominal.
DC Line Voltage:
24 Vdc nominal — 17 to 30 Vdc operational.
Wiring Requirements:
22 gauge stranded, twisted pair plus shield or
additional pair — per channel.
Station Inputs:
Microphone (electret): 2-10K ohm (dynamic): 50-200 ohm
Station Outputs:
Headphone: 150-600 ohm phones
Operating Distance:
Typical two station with a single 24 Vdc Power Supply, 1 mile without light
signalling using 22 AWG stranded, twisted cable. System performance over
long distances is directly relative to cable length, cable capacitance, wire
size, and the current drain of all of the stations connected.
