C-PHONE HE4R – HELIUM SPEECH UNSCRAMBLER

Every life support package should be equipped with the C-Phone HE4R Helium Unscrambler Communications System. The HE4R Unscrambler is unparalleled in its’ ability to decipher the helium speech associated with deep diving. It stands out from those offered by other manufacturers because of its’ unique 4 channel configuration. It uses a powerful digital signal processor to concurrently process four independent speech channels, whereas other systems mix the inputs together before putting the mixed signals through one unscrambler channel.
