• Inhalation Noise Reduction (INR)
This state-of-the-art digital technology eliminates diver inhalation noise - completely.

• High Audio Fidelity
A low noise circuit combined with noise suppression circuitry produces crystal clear speech.

• Automatic Gain Adjustment
Guards against audio signal distortion to enhance audio quality - increases bandwidth 47%.

• Extended Battery Operation Time
The state-of-the-art Class-D digital audio power amplifier provides very low power dissipation, produces less heat, and extends battery life up to 32%.

• Flexible Gain Settings
Adjustable gain settings on the amplifier card support different communication applications and environments.

• Ultra-Low Electromagnetic Interference (EMI)
Ultra-low EMI emissions achieved through spread-spectrum and de-phase control techniques provide for interference-free integration with other diving systems.


  • Inhalation Noise Reduction (INR) allows the user to adjust or completely remove each diver’s inhalation noise.
  • Each diver has an individual INR adjustment control and LED indicator to control the level of noise reduction desired.
  • INR LED indicators illuminate when the INR function is actively removing the diver’s inhalation noise.
  • Separate channels and volume controls for each diver and the tender allow individual earphone and microphone adjustments, equipment variations and comfort levels.
  • Support for 4-wire mode (full duplex) or 2-wire mode (push-to-talk) or any combination of the modes for any of the diver circuits.
  • Communicator comes standard with rear mounted MS connector, providing connections to diver and tender inputs and outputs.
  • Use dynamic or pre-amplified diver microphones – a unique circuit detects microphone type and automatically adjusts volume levels.
  • Weatherproof noise cancelling push-to-talk microphone for better tender voice intelligibility. 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 32 hours.
  • 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.
  • Ultra-low EMI emissions provide for interference-free integration with other diving systems.

  • Amron 2822-28 Remote Walk-and-Talk (4-wire mode)
  • Amron 2821-28 Remote Walk-and-Talk (2-wire mode)


  • All communicators will inherently transfer topside noise to the divers when the tender speaks directly into the communicator’s Panel Mic. To reduce topside background noise, use the 2405NC-28 Noise Cancelling Hand Held Push-to-Talk Microphone included with this model.
  • For optimum communications in normal topside environments, we recommend the 2401-28 Deluxe Headset with Boom Microphone.
  • For maximum noise cancellation in loud environments, we recommend the 2490-28 Noise Cancelling Deluxe Headset with and Boom Mic (Dual Ear Muffs).
  • To allow the tender more freedom of movement, we recommend the 2822-28 Remote Walk-and-Talk with 25 ft. cable (4-wire mode) or the 2821-28 Remote Walk-and-Talk with 25 ft. cable (2-wire mode).
