TOSHIBA Bipolar Liner Integrated Circuit Silicon Monolithic
TA2136F,TA2136N
Sound Retrieval System; 3D
Sound IC
The device incorporated the SRS; Sound Retrieval System under
license from SRS Labs, Inc.
The TA2136F/TA2136N is the IC with the Sound Retrieval
System to make 3D sound. It supports both stereo and monaural
signal inputs. This allows TA2136F/TA2136N to be suitable for
various audio systems such as TVs, stereo equipments, radio
cassette recorders, video game machines, electronic organs, and
PC units.
Features
Incorporates three mode selectors.
(1) Monaural mode (SRS 3D mono)
(2) Stereo mode (SRS 3D stereo)
(3) Bypass mode (bypass mode)
Center and space controlling functions
