SC5389S SILAN [Silan Microelectronics Joint-stock], SC5389S Datasheet - Page 7

• Manufacturer Part Number: SC5389S
• Description: 5-MODE PRESET EQUALIZER IC WITH BASS BOOSTER & 3D EFFECTS
• Manufacturer: SILAN [Silan Microelectronics Joint-stock]

It is general knowledge that different individuals have different listening preferences. The application circuit of
SC5389 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 and OUTL. 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 6dB, different capacitor values exhibit different frequency responses. Capacitor value
1800pF has a lower frequency gain response than 1200pF capacitor.
