Submarine Manufacturing & Products Limited

• Real-time audio processing uses both frequency and time domain technologies for optimized performance over a wide range of depths and background noise
• Treble Boost Control provides means of adjustment to enhance the diver’s microphone performance
• Treble Boost Control feature allows for optimum frequency enhancement and improved intelligible speech from the diver’s voice
• The Depth Control increases or decreases the diver’s depth algorithm changing the amount of correction to the raw helium speech
• Mode Switch allows for two choices of operation
  • Mode A is typically used for shallow depths with lower concentrations of Helium
  • Mode B is used for deeper depths requiring higher concentrations of Helium
• Advanced Noise Reduction Filter (NRF) incorporates a complex DSP algorithm which filters out background noise while allowing the diver’s speech to be clear and intelligible
• Noise Reduction Filter has four adjustment levels for the reduction of background noise in both depth modes A and B
  • Mode A, simply toggle the mode switch from A to B and back to A - Each time a toggle cycle is completed, the filter will advance to the next level
  • Mode B, simply toggle the mode switch from B to A and back to B - Each time a toggle cycle is completed, the filter will advance to the next level

Tech Note

All communicators will transfer topside noise to the diver when using the radio speaker only. To eliminate background noise and achieve clear concise communications, use a push-to-talk microphone or a headset or a remote walk & talk with a headset.
