Amron 2830R-01 Three-Diver Rack Mount Communicator

ENHANCEMENTS:

High Audio Fidelity

A cutting-edge, ultra-low noise circuit paired with advanced noise suppression delivers crystal-clear speech. Automatic gain adjustment prevents audio distortion while enhancing speaker protection and overall audio quality, increasing bandwidth by 47%.

Extended Battery Life

The audio amplifier card features a state-of-the-art Class-D digital audio power amplifier, which minimizes power dissipation and heat production, extending battery life by up to 32%.

Flexible Gain Settings

The audio amplifier card includes adjustable gain settings, allowing for fine-tuning based on specific communication needs and environmental conditions.

Ultra-Low Electromagnetic Interference (EMI)

EMI is minimized using spread-spectrum and de-phase control techniques, ensuring optimal compatibility with diving systems.

Audio In/Out Connections

Standard RCA audio input and output connections allow for seamless transmission of line-level signals to and from other devices. The communicator can be interconnected with two units for double redundancy or to increase the number of users.

FEATURES:

Independent channels and volume controls for each diver and tender, offering personalized earphone and microphone adjustments, equipment flexibility, and comfort customization.

Diver umbilicals can be configured in 4-wire (full duplex) or 2-wire (push-to-talk) modes, or a combination of both for each diver.

Standard rear-mounted MS connector for diver and tender input/output connections.

Supports both dynamic and pre-amplified diver microphones, with a circuit that automatically detects and adjusts for microphone type.

Weatherproof push-to-talk microphone for clearer communication at the surface. For optimal clarity, consult the Tech Note for recommended equipment.

Visual LED indicator for battery condition.

Internal charging system with battery backup allows for simultaneous operation and charging while protecting against overcharging. When AC power is disconnected, the backup battery supplies power for up to 41 hours.

TECH NOTE:

All communicators inherently transmit topside noise when the tender speaks directly into the communicator’s panel speaker. To reduce surface background noise, use the included 2405-28 Push-to-Talk Microphone. For superior communication, we recommend the 2401-28 Deluxe Headset with Boom Mic. For tender mobility, pair the 2401-28 Deluxe Headset with the 2822-28 Remote Walk-and-Talk (4-wire mode) or 2821-28 Remote Walk-and-Talk (2-wire mode). For air and helium communication, consider the 2830R-02 Three-Diver Rack Mount Communicator with DSP3 Helium Speech Unscrambler.
