TA2136FG/NG
TOSHIBA Bipolar Liner Integrated Circuit Silicon Monolithic
TA2136FG,TA2136NG
Sound Retrieval System; 3D Sound IC
The device incorporated the SRS; Sound Retrieval System under
license from SRS Labs, Inc.
The TA2136FG/TA2136NG is the IC with the Sound Retrieval
System to make 3D sound. It supports both stereo and monaural
signal inputs. This allows TA2136FG/TA2136NG to be suitable
for various audio systems such as TVs, stereo equipments, radio
cassette recorders, video game machines, electronic organs, and
PC units.
TA2136FG
Features
•
Incorporates three mode selectors.
(1) Monaural mode (SRS 3D mono)
(2) Stereo mode (SRS 3D stereo)
(3) Bypass mode (bypass mode)
