• Extended Battery Operation Time
Audio amplifier card deploys the state-of-the-art Class-D digital audio power amplifier. It 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.

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 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.
• 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.

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, topside. 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-03 Three-Diver Deluxe Portable Communicator with Wireless Tender.
