The application circuit of QS7777 is shown in Figure 9-63, and the virtual sound field positioning it generates is shown in Figure 9-640. The
two - channel three-dimensional surround sound processor is low in cost and has low requirements on the listening environment. It is suitable for
use in . With its large sound range, easy adjustment, outstanding effect, and simple system,
it is widely used in audio equipment, home theaters, televisions , multimedia computers, and many other places. Especially the virtual Dolby surround sound system that has appeared recently, using two
speakers to play back the five- channel surround sound of the Dolby surround sound system, when used in the Dolby multi-
channel surround sound system, can Enhance the sound reproduction effect. The virtual Dolby surround sound system
provides convenience for us to build a low-cost and high-quality home theater system.
These three-dimensional surround sound processors can achieve good results without requiring the programs being played to undergo special encoding.
Of course, playing live recordings and program software with encoding such as Dolby Surround works better. In addition, to achieve good
results, the adjustment of the three-dimensional surround sound processor is also very important. During use, you should adjust the effect knob reasonably and pay attention to
the appropriate "amount" of the effect.
