When the gain pots on my Xlogic SuperMicPre are in motion, I can hear an increase in noise during the gain transition?
A small amount of audible noise when the pots are in motion is expected. This is a combination of motor control cross talk, DC servo technology and mechanical noise created as the wiper moves over the potentiometer tracks. With the large amounts of gain and the implementation of direct coupled Super Analogue technology within the input amp circuit these small artifacts are inevitable. The designer has traded a small amount of pot transition noise to ensure the integrity of the sonic performance.
