The CILH Series Adapters are designed to interface low impedance military headsets to operate with civilian ICS systems. These adapters conform with all the applicable requirements of MIL-E-5400 Class 1. CILH type low to high impedance adapters incorporate both an amplifier to match microphone circuits and a transformer to match the earphone impedance. The amplifier provides amplification of signals derived from the output of a 5Ω dynamic-type microphone. The amplifier is designed to accept the DC supply voltage at the output terminals (8 to 30VDC).
