The application circuit of PT2389 included in this specification has been designed for the taste general listening public; however, you can make the necessary adjustment to suit your personal taste. Please refer to the sections below. TREBLE ADJUSTMENT The Treble adjustment is made by changing the value of the 2 capacitors connected between TL -- OUTL pins and TR -- OUTR pins. Please refer to the diagram below. As the capacitor value becomes bigger, the treble of the gain frequency curve is shifted down. Likewise, as the capacitor value becomes smaller, the treble gain frequency curve shifts the opposite direction. Referring to the diagram above, we see that at 8dB, different capacitor values exhibit different frequency responses. Capacitor value 1800 pF has a lower frequency gain response than 1200 pF capacitor. 1800pF 1500pF 1200pF Hz TL – OUTL Capacitors vs. Frequency Response Note: 1200pF PT2389 V1.5 1500pF - 11 - 1800pF July, 2006 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw 5-Mode Preset Equalizer IC with Bass Booster & 3D Effect PT2389 BASS ADJUSTMENT Bass adjustments can be made by changing the values of the capacitors connected between BL1 -- BL2 pins, and BR1 -- BR2 pins. The larger the capacitor value used, the frequency response curve shifts down. Likewise, the smaller the capacitor value, the frequency response curve shifts the opposite direction.
