Amcom™ II 2-Diver Standard Rack Mount Communicator

Amcom™ II 2-Diver Standard Rack Mount Communicator

Amron's line of Rack Mount Communicators are the most versatile and powerful communicators on the market today. The most unique feature is the design of separate channels and volume controls for each diver and the tender, both for the up-link and the down-link paths.You can set the volume for each diver and tender to their individual comfort level. Both divers can be set up on 4-Wire or 2-Wire mode, or one diver on 4-Wire and the other diver on 2-Wire mode, or any combination of the two modes.

Comes standard with rear mounted MS connector, providing connections to diver and tender inputs and outputs. All rack mount radios include a hand-held, push-to-talk microphone.


  • Volume setting for each diver and tender to their individual comfort level
  • Divers can be set up on 4-Wire Mode or 2-Wire Mode or any combination of the two modes
  • Ability to use both dynamic and preamplified diver microphones with a unique circuit that detects microphone type and automatically adjusts volume levels
  • Weatherproof panel microphone for greater voice intelligibility
  • Battery Condition Indicator - Visual LED indicator of battery condition
  • Communicator can be left on charge indefinitely without damage to the batteries or communicator
  • Communicator can be operated directly from the charger where AC power is available

Product FAQ's:

Question: How can I test for a blown fuse on my Amcom II series communicator?

Answer: If the unit is plugged into a live outlet and turning on the switch does not cause the AC POWER LED to light up, then the fuse(s) are probably blown. Unplug the unit from the outlet, remove the fuses and check continuity with a multimeter. Replace any fuse that does not show continuity.

Question: Should I use a GFI when operating my radio off AC power?

Answer: When operating your Amron Diver Communicator on AC, it is critical to use a Ground Fault Circuit Interrupter (GFCI) or isolation transformer for tender and diver safety. Surges and spikes are common on AC lines found on ships, generated locally, or at the end of long extension cable runs and can exceed 1kVolt. Such surges and spikes can cause the fuses, F1 and F2, to blow on the battery charger board and in extreme cases damage the charger circuitry. The battery charger is designed so that such a failure will be isolated and will not cause a safety issue to the tender or divers. It is strongly advised that your Amron Diver Communicator be operated on an AC circuit with a high quality surge arrester or an AC isolation transformer.

Question: When my battery does not appear to be holding a charge, how do I know if the problem is a bad battery or if the charger is broken?

Answer: To determine whether the problem is with the battery or charger you will need to verify if the charger is properly charging the battery.

Troubleshooting: Unplug your communicator and turn on the POWER switch. Measure the voltage across the yellow PUSH-TO-TALK (PTT) jack and write down this value for future reference. It should be greater than 9 Volts. Plug the communicator into an AC source and verify that the AC POWER LED on the front panel turns on. Re-measure the voltage across the PTT jack and note it down for future reference. It should be higher than the previous measurement. If this AC POWER LED does not light up when the communicator is plugged in, then check fuses F1 and F2 on the charger Printed Circuit Assembly (PCA). Allow the communicator to charge overnight. Unplug the communicator and re-measure the voltage across the PTT jack. If it is the same or less than the voltage you measured previously, then the charger is broken and the communicator needs to be sent in for repairs. If the voltage is higher than previous measurement but less than 13.5 Volts, then the battery is bad and needs to be replaced. If it is greater than 13.5 Volts but it still appears that the battery is not holding a charge, contact Amron for additional support.

Question: Can you stack the banana plugs from the diver's communicators cable so you can have two divers on each diver channel?

Answer: Although it may be possible, we strongly discourage such operation. The added workload would cause overheating and stress to the amplifier card. Prolonged use in this condition will eventually cause permanent damage and failure to the amplifier card.

Question: Can two batteries be charged at the same time if I run a splitter inline?

Answer: Yes, but it will take twice as long to charge the batteries.
