YSS915
Karaoke Processor 2 for Video disc player
(KP2V2)
INTRODUCTION
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).
FEATURES
[ Fundamental Functions ]
1) Karaoke program

3. Analog audio interface
MICIN, ADC1, ADC2, AOL, AOR, VREF
This LSI has a one channel (MIC input) of Delta-Sigma type A/D converter, thus requiring the external circuits as
described below.
The output of AOL and AOR can be used as a direct signal from the microphone because the volume of the signal is
controlled as analog signal which is outputted from AOL and AOR.
