General Description

The HT8972 is an echo/surround effect processor. It is

designed for various audio systems including karaoke,

television, sound equipments, etc. The chip consists of

a built-in pre-amplifier, VCO or Voltage Control OSC,

40Kb SRAM, A/D and D/A converters as well as delay

time control logic.

Its built-in 40Kb SRAM can generate delay time effect

and can control the delay time value through the exter-

nal VCO resistor.

The VCO circuit can reduce external components and

make it easy to adjust the delay time.
