Bass Amplifier MM1124
Outline
This IC was developed to boost bass on TV and free-standing VCR decks, etc.
The recent trend toward large-screen TV and movie software has increased the demand for powerful bass
and wider sound, so that the bass boost function has become part of TV and VCR functions.
This IC was designed especially for bass, and easily reproduces a powerful sound.
Features
1. Dynamic bass boost
Boost can be adjusted higher for lower sound, and smaller for bigger sound.
2. Boost switching pin
Boost amount can be switched for music and video software, giving a change to the set
3. High range boost
By boosting the high range as well, a more realistic sound is reproduced
4. Boost attack circuit
Gives quick response and follows sudden volume changes
