FUNCTIONAL DESCRIPTION
SC5389
SC5389 is a 5-Mode Preset Equalizer IC with a Bass Booster and 3D Effects. It has 2 types of key selection mode, namely: Direct and Cyclic. The Direct or Cyclic Key Selection Mode are determined by the SEL pin. Please refer to the table below: Key Selection Mode SEL Pin Description Press FLAT key to active Flat Mode Press ROCK Key to activate Rock Mode Direct Low Press POPS Key to activate Pops Mode Press CLASSIC Key to activate Classic Mode Press JAZZ Key to activate Jazz Mode Cyclic* Floating / High
Flat Jazz Rock Pops Classic
Note: The Bass Booster Function and the 3D Effect can be controlled in the same manner under the Direct or the Cyclic Key Selection Mode. To turn the Bass Booster On or Off, press the BB Key. To turn the 3D Effect On or Off, press the 3D key. * = Under the Cyclic Selection Mode, press the CYC key, to go to next sound selection.
Cyclic Key Selection Mode
As seen in the table above, the Cyclic Key Selection Mode is active when the SEL Pin is Floating or "High". Under this mode, any of the sound selections (Flat, Rock, Pops, Classic, Jazz) may be selected by pressing the CYC Key. The default value is the Flat Mode. This means that when power is turned ON, the Flat mode is active. Pressing the Cyclic Key lets you go from one sound selection to the other in the following order: Flat - Rock - Pops - Classic - Jazz. Please refer to the diagram below.

The BB Key controls the Bass Booster. When the power is turned ON, the Bass Booster is OFF. Likewise, the 3D Key controls the 3D Effect. When the power is turned ON, the 3D Effect is OFF.
Direct Key Selection Mode
The Direct Key Selection Mode is active when the SEL Pin is set to "LOW". As the name implies, you can directly select the sound selection you like (Flat, Classic, Rock, Jazz, or Pops) simply by pressing the respective keys. This means, that to select the Jazz mode, press the JAZZ Key, Classic Mode, press the CLASSIC Key and so forth. Take note that when the power is turned ON, the Flat Mode is active. The Bass Booster Function and 3D Effect are independent of the key / sound mode selected and may be turned On or Off at any time.

TREBLE AND BASS ADJUSTMENTS
SC5389
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.
+12 +11 +10 +9 +8 +7 +6 +5 +4 dB +3 +2 +1 0 -1 -2 -3 -4 20 50 100 200 500 Hz 1k 2k 5k 10k 20k 1500pF 1200pF 1800pF
TL-OUTL Capacitors vs. Frequency Response 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.

Bass Adjustment
SC5389
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 capacitor value, the frequency response curve shifts the opposite direction. Please refer to the diagram below.
+12 +11 +10 +9 +8 +7 +6 +5 +4 dB +3 +2 +1 0 -1 -2 -3 -4 20 50 100 200 500 Hz 1k 2k 5k 10k 20k 0.068f 0.1f 0.056f
BL1--BL2 Capacitor vs. Frequency Response Curve
In the diagram above, at 9 dB - different capacitor values exhibit different frequency responses. A capacitor with a value of 0.1f has smaller frequency response than a 0.056f capacitor.
