In stock

NEWLY DESIGNED 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 bandwidth 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.

FEATURES:

  • Diver umbilical connections on the front panel are 5-pin MS (Military Standard) connections.
  • 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 to 4-wire mode (full duplex) or 2-wire mode (push-to-talk) or any combination of the two modes for any diver.
  • 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.
  • An internal charger allows for simultaneous charging and operation of the unit while protecting the rechargeable battery from being over-charged.  Automatically supplies power to the audio amplifier when AC power is disconnected to allow for continued operation.

  • Amron 2460-28 Standard Operator Headset with Boom Mic and Dual Banana Plugs

TECH NOTE:

All communicators will inherently transfer topside noise to the divers when the tender speaks directly into the communicator’s panel speaker. To eliminate background noise at the surface, use the 2405-28 Push-to-Talk Microphone, included with this model. For optimum communications, we recommend purchasing the 2401-28 Deluxe Headset with Boom Mic for topside operation. For tender mobility, use the 2401-28 Deluxe Headset with Boom Mic along with the 2822-28 Remote Walk-and-Talk (4-wire mode) or the 2821-28 Remote Walk-and-Talk (2-wire mode). For wireless tender communications, order the 2830A-16 Three-Diver Rechargeable Portable Communicator with MS Connectors and 28B Wireless Tender Option, Outdoor AC Power Module, and International Locking Power Cord.
