GENERAL INFORMATIONGENERAL INFORMATION 2.1The AMCOM Rack Mount series of diver communication systems are full feature hard wire, threediver communicators.The units are designed for system integration; the enclosure can be mounted in a standardelectronic relay rack. All inputs/outputs are available on the rear of the unit for a clean and neatinstallation.All standard units can be operated from either a 110/220 VAC and internal 12 VDC battery.The AMCOM III has the capability of 2-wire and/or Simulcom (4-wire) communication modes. 2-Wire and Simulcom (4-wire) modes can be used simultaneously. Simulcom is a communicationssystem designed from the “ground-up” to take advantage of the current “state of the art” insemiconductor technology and provide superior diver hard wire communication.This diving communicator has the ability to work with both dynamic and pre-amplified microphonesin either 2-wire or 4-wire modes. The circuit detects the type of microphone that each diver isusing then automatically switches from the preamp mode to dynamic mode, adjusting the specificdiver’s gain (volume).2
