Low Vol Ref 
Reference level for highest Bass/Treble amplification, referenced to the Volume set in dB. 
Available range is -90 dB to -20 dB. Default: -30 dB. A volume setting below this point will have 
maximum Bass/Treble gain, all volume settings above this point will have lower Bass/Treble 
gain. 20 dB above the Low Vol Ref setting the Bass/Treble gain will be zero. 
Note that changing the Ref Level will need a manual update of the Low Vol value. Loudness is 
therefore most efficient in Auto Ref Level mode.
