Automatic Level Control

circuit
configuration is shown in Figure 4. It can be seen that it is
quite similar to the compressor schematic except that the
input to the rectifier cell is from the input path and not from
the feedback path. The input is AC coupled through C12
and C13 and the output is AC coupled through C8. Once
again, as in the previous cases, if the system input and
output signals are already AC coupled, then C12, C13 and
C8 could be eliminated. Concerning the compressor,
removing R6, R7 and C7 will cause motor-boating in
absence of signals. CCOMP is necessary to stabilize the
summing amplifier at higher input levels. This circuit
provides an input dynamic range greater than 60 dB with
the output within
"0.5 dB typical. The necessary design
respectively.
