All inputs tested, and pass audio, no noisy sliders or pots. All phantom mic feeds work. Not new but only used around 10 times a year. Housed in 19” racks in an AC controlled office environment.  

One mixer input has an occasional “scratchy/noise”. With slider at minimum, gain at minimum, or mute operated, there is no breakthrough onto the audio buss.
