Overview
The STK301-220 is a hybrid IC (HIC) for electronically
controlled graphic equalizer applications and is equipped
with on-chip electronic volume control for 7-band, 2-
channel graphic equalization, thereby permitting one-
touch up-down control of all band gains. The STK301-
220 is a hybrid IC which combines SC system and
photoresist techniques with folded board construction
while incorporating Sanyo’s unique insulated metal
substrate technology (IMST) to the base.
Applications
Car stereos
Portable radio-cassette players
Home stereos
Features
All bands are set for L/R simultaneous 2 dB incremental
operation (typ).
All bands are equipped with 13 positions and range
between +12 dB maximum boost to –12 dB maximum cut.
Crossover frequencies include fo; 60 Hz, 150 Hz,
400 Hz, 1 kHz, 2.5 kHz, 6 kHz and 15 kHz.
The following features can be made available with an
electronic graphic equalizer system which incorporates
the 3-IC construction consisting of the STK301-220, a
controller (universal microcontroller) along with the
display LSI (LC75821
→
LCD, LC7565
→
FLT, LED):
— One-touch up-down control of all band gains.
—
Immediate recall of preferred frequency levels tailored
to suit musical selections. This is possible using preset
functions to retrieving items from one-touch memory
.
— Such functions as setting all bands to 0 dB (flat
function), or switching frequency characteristics
from 0 dB to center (reverse function) may be
simply performed with supported software.
— Dual control lines permit mutual use with display
LSI and help to simplify wiring between
microcontroller and LSI.
Minimal operating shock noise when boost or cut is used.
