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.

• Audio In/Out Connections
Audio IN and audio OUT RCA connections supplied for receiving and sending standard audio line-level signals to and from another device. Two rack mount communicators can be interconnected for double redundancy requirements and/or can double the number of users as needed.

FEATURES:

• Separate channels and volume controls for each diver and tender to accommodate individual earphone and microphone adjustments, equipment variations and individual comfort levels.

• Divers’ umbilicals can be set up on 4-wire mode (full duplex) or 2-wire mode (push-to-talk) or any combination of the two modes for each diver.

• Communicator comes standard with rear mounted MS connector, providing connections to diver and tender inputs and outputs.

• Ability to use both dynamic and pre-amplified diver microphones with a unique circuit that detects microphone type and automatically adjusts volume levels.

• Weatherproof push-to-talk microphone for better voice intelligibility topside.  For optimum clarity, see Tech Note (below) for other recommended equipment.

• Battery Condition Indicator - Visual LED indicator of battery condition.

• Internal charging system with battery back-up allows for simultaneous charging and operation of the unit while protecting the rechargeable battery from being overcharged.  Back-up battery automatically supplies power to the audio amplifier when AC power is disconnected to allow for continued operation up to 45 hours.
