TONE CONTROL
Figure 12 Tone Control
The Tone Control panel is used to control the various tone options (3D, Bass, Treble, etc)
offered by the WM8973. The sliders update in ‘real’ time (i.e. the ‘Tone Submit’ button does
not have to be pressed to update the relevant tone slider level). Pressing the ‘Tone Submit’
button will cause the settings shown on this panel to be written to the WM8973. A full device
register write is not sent.
It is important to note that to change the ‘3D Select’ control setting from Record to Playback,
the ADC and DAC must be set to a power down state in the Power Down and Interface
Control panel. After the ‘3D Select’ setting has been made and written to the WM8973 the
ADC and DAC should be powered up.
Once any of the WM8973 default settings are changed on the control panel, the relevant
section is highlighted in blue to show the section where the setting has changed. The
highlight around the relevant section also has the purpose of letting the user know that they
have not yet submitted the required changes to the WM8973. After a Submit from the
relevant panel or a main panel Submit, the sections will default back to their original 'panel
grey' colour. The Submit button also becomes inactive until another change is made to the
register settings.
Refer to the Appendix Section of this user manual for additional evaluation board setup
details.
