The latest settings which can be changed to the zones are the two
band tone control. The tone control can be activated by selecting
the “Bass” and “Treble” buttons, and the adjustment of the tone
control works with a fader just as the volume control. You can
increase and decrease the high and low tones the same way as
adjusting the volume, by simply rotating the selection dial. The
Bass and Treble both can be adjusted between the ranges of
+9dB and -9dB.
The latest selection button is the “Back” button. By clicking this
button, you will return to the main screen where zone selection
can be made.
