Soft Mute (SMUTE)
Soft mute operation is performed in the digital domain. When SMUTE bit goes to “1”, the output signal is attenuated by
∞ (“0”) via the cycle set by ATS bit (Table 20). When SMUTE bit returns to “0”, the mute is cancelled and the output
attenuation gradually changes to 0dB via the cycle set by ATS bit. If the soft mute is cancelled within the cycle set by ATS
bit after starting the operation, the attenuation is discontinued and returned to 0dB. The soft mute is effective for changing
the signal source without stopping the signal transmission.

Notes:
(1) The output signal is attenuated until
∞ (“0”) by the cycle set by ATS bit.
(2) Analog output corresponding to digital input has the group delay (GD).
(3) If the soft mute is cancelled within the cycle set by ATS bit, the attenuation is discontinued and returned to the
setting value by the same cycle.
