YSS247 application circuit

Compared with similar products, YSS247 has the following characteristics: fewer peripheral components. Different from SRS5250S,
YSS247 only needs one potentiometer to adjust the surround effect. Tone control and surround effects can be switched on or off via switches . The stereo positioning of the YSS247 application circuit is accurate, the three-dimensional space effect is outstanding, and the sense of space in the horizontal direction is strong. In particular , the center channel is accurately positioned and does not need to be adjusted. The tone control range of YSS247 is: bass 100Hz±10dB, treble 10kH2;±10dB, signal-to-noise ratio of 95, and distortion of 0.0025%. It can be seen that its performance is still good. .     When making this circuit, pay attention to selecting high-quality components. Pay special attention to the quality of the double potentiometer, otherwise the poor symmetry of the double potentiometer will affect the tone adjustment and two-channel surround effect. Next, we will introduce an application circuit     of YSS247 . The circuit diagram is shown in Figure 9-52.     This circuit can carefully adjust the surround effect through the switch. You can also use the switch to adjust the center frequency of the tone control , which can achieve better results and the simulated three-dimensional surround sound field is more realistic and natural.
