High performance digital
echo circuit thanks to
16Kbit
memory
Built-in
surround function
which works
Simulated Stereo
for
monaural source and
Stereo Surround
for stereo source
ALC-equipped microphone amplifiers
permit excessively
high input.
ALC operating voltage
can be set as desired.
2 microphone volumes, echo effect volume
and
echo
feedback volume
are included
Stereo microphone-line
mixing amplifiers
Karaoke entertainment functions such as
vocal cut
and
automatic vocal support
system
Built-in
current-control oscillation
circuit
Built-in automatic reset circuit activated with power on
5V single power supply
The M65853 is a CMOS IC built-in Digital Echo function with microphone peripheral circuits for
"Karaoke" equipment packed in a single chip.
It is suitable for "Karaoke" equipments such as Video CD Player, Mini Stereo, CD-Radio Cassette, TV
or VCR.
