HA12206 - Audio Signal Processor

Description

HA12206NT is silicon monolithic bipolar IC providing music sensor system, ALC, REC equalizer system and each electronic control switch in one chip.

REC equalizer

Line Amp.

ALC (Automatic Level Control) MS (Music Sensor)

Features

  • REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics.
  • Correspondence with normal position (TYPE I) / high position (TYPE II).
  • TYPE I / TYPE II and PB equalizer fully electronic control switching built-in.
  • Controllable from direct micro-computer output.
  • Available to reduce substrate-area because of high integration and small external parts. HA12206NT Pin.
