AUDIO INPUTS
Microphones
Supervisor and Operator Headsets Inputs for two simulated carbon telephone-style headset
microphones similar to Plantronics model HS-0309-1. Approx.
input impedance = 150 ohms. Typical input = 100 mV rms
(-12 dBm). Nominal input range = -18 to -6 dBm. ALC
controlled. DC mic bias = 3.0 ±0.5 Vdc with 50-ohm load.
