2830A THREE DIVER COMMUNICATOR USER MANUAL 

 

2830A-UM 

REV 5.0 

11 

4.6 

OPTION CONTROLS: HELIUM SPEECH UNSCRAMBLER/26DSP3 

The  controls  for  the  DSP3  Helium  Speech  Unscrambler  (HSU)  are  located  in  the  options 
panel on the right side of the front panel as shown below. 

 

4.6.1 

ON/OFF SWITCH 

–

 Allows the selection of air (OFF) or helium (ON) operation. In 

the  OFF  position,  the  divers’  microphone  signal  bypasses  the  HSU.  In  the  ON 

position, the microphone signals are routed to the HSU and the tender can adjust 
the controls as necessary. 

4.6.2 

TREBLE BOOST 

–

 Selects the amount of gain added to the High Frequency (HF) 

portion of the divers’ microphone signals. This compensates for the HF drop

-off in 

the  sensitivity  of  most  microphones.  The  TREBLE  BOOST  feature  allows  for 

optimum frequency enhancement and improved intelligible speech from the diver’s 

voice.
