The AMCOM™ II Two-Diver Rechargeable Basic Portable Communicator with Outdoor Power Module and International Locking Power Cord features a single channel and one volume control for both diver’s uplink and downlink communications to and from the tender. [1]

The newest version of the AMCOM™ II has the same user-interface, rugged durability and great sound quality as its predecessor with several new digital enhancements:

• High Audio Fidelity
Ultra-low noise circuit combined with noise suppression circuitry produces crystal clear speech. Automatic gain adjustment will guard audio signal from distortion, enhance speaker protection and audio quality. Increases band width 47%.

• Extended Battery Operation Time
Audio amplifier card deploys the state-of-the-art Class-D digital audio power amplifier. Has very low power dissipation, produces less heat, and extends battery life up to 32%.

• Flexible Gain Settings
The audio amplifier card has adjustable gain settings to accommodate different communication applications and environments.

• Ultra-Low Electromagnetic Interference (EMI)
EMI is achieved through spread-spectrum and de-phase control techniques providing for optimum integration with diving systems.

• Outdoor Rated AC Power Module
Weather resistant, IP65 rated AC power entry module accommodates country specific AC power cords.

• Country Specific V-Lock AC Power Cord
At time of order, simply choose the IP54 rated Locking AC power cord you need.
