Tone control include subwoofer out
PT2350 is a tone control subwoofer cross-over low pass filter chip utilizing CMOS Technology. It features a tone control range of + 10dB (50Hz, 4 KHz) and subwoofer low pass filter of the second order Sallen Key Design. The roll-off point can be adjusted by changing the value of the external capacitor. Pin assignments and application circuits are optimized for easy PCB Layout and cost saving advantages. CMOS Technology 2-Channel Input 3-Channel Output (Including 1 stereo Output and Subwoofer Output) Low Total Harmonic Distortion (THD<0.01%, Subwoofer THD<0.2%) High S/N Ratio (S/N Ratio <-87dB, A-weighting) Least External Components Adjustment of Frequency response by changing the value of the external component Single Power Supply: 3 to 8.5 Volts Available in 20 pins, DIP or SO Package PARTS Resistors 2------ R1,R2-------------- --------- 10k / 1% / metal film Capacitors 2------ C9,C10------------- -------- 4.7nF / 63V / polyester / raster R. 5mm 3------ C1,C7,C8-------- -----...
