GENERAL INFORMATION 2.1
The AMCOM III series of diver communication systems are full featured, hard wired, three diver
communicators. The AMCOM III has independent microphone and earphone volume controls for
each diver and the tender.
All AMCOM III series have push-to-talk, and separate isolated inputs for each diver. The AMCOM
III Model 2830A/24 is a portable three diver communication systems, delivering 20 watts "voice
power", operating from either a 115/230 VAC, external 12 VDC power source, or an internal 12
VDC backup battery.
The Model 2830A 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 communications
system designed from the "ground-up" to take advantage of the current "state of the art" in
semiconductor technology and provide superior diver hard wire communication.
This portable diving radio has the ability to work with the Dynamic and Pre-Amplifier microphone in
both 2-wire and 4-wire modes. This unique design has the ability to detect both pre-amp and
dynamic diver microphones that are in use. This feature will automatically switch from a preamp
mode to a dynamic mode and will adjust the specific diver gain (volume).
The Model 2830A’s with 20 watts of power is the most powerful communicator on the market. The
untouched volume and clarity allows the tender’s volume to be set at very high levels especially in
noisy environments while the divers are at a comfortable listening level.
