Amron AMCOM™ III 2830A-12: Three-Diver Portable DSP3 Helium Speech Unscrambler

Real-time audio processing uses both frequency and time domain technologies for optimised performance over a wide range of depths and background noise

Improved Treble Boost Control feature allows for optimum frequency enhancement and improved intelligible speech from the commercial diver’s voice

Multi-turn Depth Control allows the tender to finely adjust the amount of correction used to provide the best possible speech quality

The Noise Reduction Filter (NRF) uses a complex Digital Signal Processor algorithm to capture the background noise and reduce it without affecting the diver’s speech

Noise reduction level can be reduced by up to 17 dB

Input Impedance (Each Input):250 Ohms

Frequency Response:300 – 10000 Hz

Common Mode Rejection: 40 dB Minimum

Current Drain Maximum Full Volume: 3 Amps

Minimum Quiescent:0.190 Amps

Output Impedance:4 Ohm

Used for both above and below water with a waterproof microphone that reduces background noise.

Suitable device, designed for both air and mixed gas diving.
