[sdiy] Karaoke boom-box echo chips

[anthony]

Worked like a charm! But the datasheet PDF's have to have their text as text 
and not just scanned images. Or maybe there's an OCR function I didn't take 
davantage of. I didn't need to: my datasheet was text. Most of the 
translations were pretty intuitive and just as frustratingly uninformative 
at times as datasheets are when they are in English!

But I always say: a datasheet with a couple of good schematics and no words 
is better than 10 pages of description and no schematics.

My Semicon CD3699 can be used as either a karaoke machine echo or provide 
"surround sound delay" which explained the different schematics. Says it has 
a high S/N (which I discovered through translation). Let's hope it's better 
than the chip in the Barbie (tm) Karaoke boombox I have been experimenting 
with without the aid of a schematic. I may end up simply boxing the circuit 
board up all kit and kaboodle since it's not that big, well it's broken up 
into two pieces.

My plan for these was to use them in Circuit bending-type creations. Except 
I don't "bend" in the strictest terms. I figure out hwat does what and 
modify it based on more of a synth-diy approach. Still, adding echo to my 
collection of talking VTech learning toys will be such FUN! HAHAHAH!

Unless the sound quality does indeed merit their use in one of my synths...

Thanks,
Anthony
