What is this feature?


My reference amp, an integrated Myryad, once turned on reverts the volume to a very low decibel level hence removing the dreaded "did I just blow out my speaker moment?"
All of my other amps do not have this feature. Is there a name for it? Any negatives to it other than an added complication? Thanks.

On my Anthem A/V receiver, I can pre-set startup volume for each input, IIRC.

On my Gato pre, "When the preamplifier enters standby mode again it will remember the selected input channel and volume level. If the volume level is higher than 50, it will be reduced to 50 when the preamplifier exits standby mode."
