MUTE setting example
When changing Input Selector or Input Gain, the Soft-switching is not applied. Therefore, it is recommended to
implement the MUTE function.
On Soft-switching of the RECOUT, Surround, and Rear Volume functions, data must not be sent serially to the
functions before the switching operation is completed.
While muting Volume, to avoid increasing residual noise, set Bass, Middle and Treble to 0dB, Surround to OFF, and
Rear Volume to -10dB.
