12. CONTROL SETTINGS
Output levels are adjustable with individual volume controls. For music play or announcements, adjust the
corresponding volume control so that the red indicator doesn't light. Note that the sound quality is downgraded
when the red indicator remains lit.
To prevent the accidental change of the settings of input volume and tone (Bass and Treble) controls, remove
their knobs after setting them to the desired position and attach the optional YA-920 Volume Control Covers
instead.
