Signal Flow
The microphone signal enters the Model 188 through the female XLR, through a switch
for the Pad (-26dB), the mic pre front end including the transformer with 26dB of gain
and the low cut  lter, polarity reverse, through the variable gain ampli er (0 to 39dB of
gain), to the A/D converter and the output stage. Note: if the analog output is in “pre”
mode the output gets its signal after the front end but before the variable gain ampli re.
