CASCADE CONNECTION
Additional noise reduction can be obtained by cascading the
DNR filters. With two filters cascaded the rolloff is 12 dB per
octave. For proper operating bandwidth the capacitors on
pin 3 and 12 are changed to 15 nF. The resulting noise
reduction is about 17 dB.
Figure 15 shows the monaural cascade connection. Note
that pin 14 is grounded so only the pin 2 input is fed to the
summing amp and therefore the control path.
Figure 14 shows the stereo cascade connection. Note that
pin 14 is open circuit as in normal stereo operation.
