Operation
Volume
The large green number in the top right corner shows the master volume. 
The volume range is from 0-103. Set volume levels can be programmed 
so that when the SP20 is initially powered on, the volume is always 
at the same number. Likewise, individual set volumes for the speaker 
(main) outputs and headphone output can be set to prevent unexpected 
volumes while switching between outputs. See ‘Volume Presets’ in the 
settings menu for further instructions on setting output levels.
