Figure 7.
1. Please notice that a started mute-action is always terminated and could not be interrupted by a change of
Soft-step volume
When the volume level is changed audible clicks could appear at the output. The root cause
of those clicks
could either be a DC-Offset before the volume-stage or the sudden change of the envelope
of the audiosignal. With the soft-step feature both kinds of clicks could be reduced to a
minimum and are no more audible. The blend-time from one step to the next is
programmable in four steps.
Figure 8.
1. For steps more than 0.5dB the Soft-step mode should be deactivated because it could generate a hard
Bass
There are four parameters programmable in the bass stage:
the mute -signal
1dB step during the blend-time.
