DESCRIPTION
The TDA7444 provides a complete solution for
Pro Logic decoding with 2 analog inputs and 4
analog outputs and a Stereo Digital Input/Output.
The @VMAX and @TruSurround give 3D effects
on a Prologic Source using only two analog out-
puts.
SRS matrix creates a fully immersive 3D sound
with a stereo or a mono source from two stereo
speakers.
A 3 band stereo graphic equalizer, a loudness
and a volume control are available to enhance
the sound effect in quality audio applications as
TV set and Hi-Fi systems.
