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.
