Overview
The LA2655V is an IC for the sound replay which can be
used for the audio equipment such as the radio cassette re-
corder, the personal computer, the stereo, and the televi-
sion.
This IC has the function to replay a clear sound.
Features
Provides improved audio quality from one-way speaker
systems by incorporating the SANYO algorithm “Plus
Sound
”, which corrects delay and attenuation differences
between high and low frequencies due to the characteris-
tics of the speaker.
Functions
“Plus Sound
” algorithm provided on chip.
Clear sound signal processing.
Variable effect level (with external parts).
Effect ON/OFF switch.
