Descriptions
The Amcom™ II Series 2820A diver communication radio system is a full featured hard wire, two diver communicator. The 2820A models have a single earphone volume control for diver's volume (down-link) and a single volume control for the tender (up-link).All Amcom™ II series communicators have Push-to-Talk and separate isolated inputs for each diver. The Amcom™ II Series portable communications system delivers 20 watts "voice power"; operating from internal batteries or external 12 VDC power source. Models with the /23 or /24 option can be operated from either a 110/220 VAC, external 12 VDC power source, or an internal 12 VDC battery. All Amcom™ II Series communicators have the capability of 2-wire and/or 4-wire communication modes. 2-Wire and 4-wire modes can be used simultaneously.
The Amcom™ II Series communicator has the ability to work with both dynamic and pre-amplified microphones in either 2-wire or 4-wire modes. The circuit detects the type of microphone that each diver is using then automatically switches from the preamp mode to dynamic mode, adjusting the specific diver's gain (volume). The tender's volume is set louder than the diver's volume. This allows the tender to hear the diver in a noisy environment while maintaining the diver's volume at a comfortable level.
