Amcom™ II DSP2
2-diver rack mount helium speech unscrambler
Amron's new DSP2 Helium Speech Unscrambler (HSU) utilizes the latest in technological advancements. The heart of our design incorporates dual digital signal processors. This revolutionary concept allows our HSU to be truly the first unscrambler to use both frequency and time domain technologies for real-time audio processing. This state-of-the-art digital design accommodates a multitude of functions ranging from the correction of the diver's raw helium speech to normal intelligible voice levels, advanced treble boost and complex noise reduction filters (NRF).
- 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
