PLL FM Multiplex Stereo Demodulator (=KA2262)
- Stereo noise control (SNC terminal)
Through controlling the quality of sound from stereo mode to monaural mode with the voltage applied to the control pin, the FM stereo noise in the weak electric field is reduced by this function.
- High-cut control function (HCC terminal)
The FM noise in the weak electric field is reduced through the attenuation of high frequency thereof. Such attenuation can be changed smoothly from "Normal" to "High Cut" by controlling the voltage applied to the control pin. The volume of "High Cut" can be selected by using an external capacitor.
- Stereo-monaural automatic select
This selection has priority over the stereo noise control. Pilot input prioritized.
- Stoppage of VCO oscillation
When a voltage of 7.5V or higher is applied to the HCC terminal, the oscillation of VCO can be discontinued. In this case, the stereo lamp does not malfunction.
