Soundhound,

Does your analog hiss increase with volume or trim? In mine, the hiss increases during the setting (via the calibration menu) of trim, but after the trim has been set, the analog hiss stays pretty much the same. Also, in mine, the analog hiss is not much different with the volume knob at -79 db as with the knob at -1 db. In analog, the hiss is just, well, there.
