Figure 4. Basic Components
Figure 4 shows the hook-up for a compressor. This is essentially an expandor placed in the feedback loop of the
op amp . the
G cell is setup to provide AC feedback only, so a separate DC feedback loop is provide by the two
R
DC
and C
DC
. The values of R
DC
will determine the DC bias at the output of the amp. The output will bias to:

The output will bias to 3.0V when the internal resistor are used. External resistor may be placed in series with r3,
(which will affect the gain ), or in parallel with r4 to raise the DC bias to any desired value.
