5. Fader
The configuration of the fader circuit is shown in Fig. 7. The fader operates by specifying the amount of
attenuation for either the front or rear output signal and by specifying which output signal (front or rear) is to
be attenuated.
The input impedance is 24k (typ.) for FDIN1 and FDIN2.
The output impedance for FNTO1, FNTO2, REO1, and REO2 is low impedance (roughly 0 ). The gain and
fader step width are not affected by the load impedance.
