DOLBY PRO LOGIC & DOLBY3STEREO.
Situs The surround system reproduces video software program carrying
the DX) (Dov sunncuno| mark with similar acoustic effects to movie
theaters.
The DOLBY PRO LOGIC mode controls the audie signals of the
Front Left/Right. Center and Rear surround channels using the
built-in directivity enhancer circuit to reproduce the feeling of
sound motions realistically.
The DOLBY 3 STEREO mode can reproduce the motions of sound
even when only the front and center speakers are used, by
providing proper acoustic position using the directivity enhancer
circuit
This mode adds presence sound components obtained fram the
DSP (Digital Signal Processor) to the signals output from the
DOLBY PRO LOGIC (Left, Center, Right and Surround channets},
allowing movie software programs to be played with a similar
feeling of presence to movie theaters in a listening room in home.
DSP presence This mode adds presence sound components obtained from the
DSP (Digital Signal Processor} to the original source signals,
allowing music source entertainment with the feeling of pres-
ence in an arena, stadium or jazz club in a listening room at home.
