HA12211NT - Audio Signal Processor

Description

HA12211NT is silicon monolithic bipolar IC providing REC equalizer system, PB equalizer system and each electronic control switch in one chip.

PB equalizer × 2 channel REC equalizer × 2 channel Each electronical control switch to change equalizer characterist

Features

  • REC equalizer is very small number of external parts. (4 types of frequency characteristics built-in).
  • PB equalizer built-in. (A/B input changing system, 4 types of frequency characteristics).
  • Independent PB sensitivity for A deck, B deck.
  • Normal-speed/high-speed, normal tape/chrome tape switching built-in.
  • Controllable from direct micro-computer output.
  • Available to reduce substrate-area because of high integration and small external part.
