I bought the TipTop Audio - Fold Processor and while testing it, I discoverd, that without an input signal and when I turn the "Inject"-Knob there came some noise on the out, not very loud, but absolutely audible and a little bit anoying.
My question is:
Is this a normal/default behaviour or is it a production/manufacturer error?
Because, if i send a signal thru the Fold Processor and I have an unfavorable "Inject"-Knob position, the noise is clearly audible in the input signal on the out; on another position, it is there is no noise audible, but I think this may not be valid behavior.
Please help me out.
Thanks in advance.
