... Note: Modifying the values of Rx and Cx affects the Oscillator Frequency of the IC. If the Fosc value is big, then the volume control change is fast. Likewise, if the Fosc value is small, the volume control change is slow suggested that Rx= 33K 2.2uF. The table for the Rx, Cx and Fosc values are given below PT2256 v1.3 URL: http://www.princeton.com.tw 100 ...
