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 fi lter, polarity reverse, through the variable gain amplifi 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 amplifi
re.
