Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained

Overview
The LA2610 is an ambiance reproduction processor for
use in audio, TV, and personal computer equipment
applications. This IC easily reproduces a live space filled
with a sense of presence by processing stereo signals
from musical and audio-visual sources.
Features
• Wide operating supply voltage range allows various
applications to be used.
• Aggregate level tuning is possible for surround signals
and bass-boost signals.
• Miniature package and fewer external components
allow the mounting area to be reduced.
• Bypass mode for low noise and low distortion ratio.
Functions
• Surround signal processing.
• Simple bass-boost.
• Switching between surround and bypass modes.
Package
• SIP12S
