Soft Mute
Soft mute operation is performed in the digital input domain. When the SMUTE bit goes to
“
1
”
, the input signal is
attenuated by
∞
(
“
0
”
) during the cycle of 256/fs (5.8msec@fs=44.1kHz). When the SMUTE bit is returned to
“
0
”
, the
mute is cancelled and the input attenuation gradually changes to 0dB during the cycle of 256/fs (5.8msec@fs=44.1kHz).
If the soft mute is cancelled within the cycle of 256/fs (5.8msec@fs=44.1kHz), the attenuation is discontinued and
returned to 0dB. The soft mute for Playback operation is effective for changing the signal source without stopping the
signal transmission.

(1)
The input signal is attenuated by
∞
(
“
0
”
) during the cycle of 256/fs (5.8msec@fs=44.1kHz).
(2)
Analog output corresponding to digital input has the group delay (GD).
(3)
If the soft mute is cancelled within the cycle of 256/fs (5.8msec@fs=44.1kHz), the attenuation is discounted and
returned to 0dB within the same cycle.
