AM/FM Stereo Tuner.
The IF stages use two high quality ceramic filters, plus discrete and integrated circuit amplification. The discriminator is of the quadrature detector type with a double - tuned coil, resulting in exceptionally low distortion figures. Stereo decoding is by means of a phase -locked loop IC, which also achieves a low level of harmonic distortion, allied to a high degree of spurious response rejection. This feature is further aided by the addition of extra filters to remove the residual 19kHz pilot tone and its harmonics.
Signal/noise ratio is 70dB (in mono mode),
Stereo channel separation is 34dB at 1kHz, and the audio output is adjustable up to 1V (5kΩ source). De-emphasis of 50µs or 75µs is available.
