YSS915 (KP2V2) is an LSI for processing Karaoke voice signals. This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that YSS915 is applicable to various uses. In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the surround effect is applied to the movie and music sources for giving the users more enjoyment. YSS915 is pin compatible with and register compatible with YSS903 (KP2V).-YSS915 (KP2V2) is an LSI for processing Kar aoke voice signals.
