HA12209F
Audio Signal Processor for Cassette Deck
(Dolby B-type NR with Recording System)
ADE-207-221A (Z)
2nd Edition
Jun. 1999
Description
HA12209F is silicon monolithic bipolar IC providing Dolby noise reduction system*, music sensor system,
REC equalizer system and each electronic control switch in one chip.
Functions
• Dolby B-NR × 2 channel
• REC equalizer × 2 channel
• Music sensor × 1 channel
• Each electronic control switch to change REC equalizer, bias, etc.
Features
• REC equalizer is very small number of external parts and have 4 types of frequency characteristics
built-in.
• 2 types of input for PB, 1 type of input for REC.
• 70µ-PB equalizer changing system built-in.
• Dolby NR with dubbing double cassette decks.
Unprocessed signal output available from recording out terminals during PB mode.
• Provide stable music sensor system, available to design music sensing time and level.
• Controllable from direct micro-computer output.
• Bias oscillator control switch built-in.
• NR ON/OFF and REC/PB fully electronic control switching built-in.
• Normal-speed/high-speed, TYPE I/TYPE II and PB equalizer fully electronic control switching built-in.
• Available to reduce substrate-area because of high integration and small external parts.

Note:
Depending on the employed REC/PB head and test tape characteristics, there is a rare case that the
REC-EQ characteristics of this LSI can not be matched to the required characteristics because of
built-in resistors which determined the REC-EQ parameters in this case, please inquire the
responsible agent because the adjustment of built-in resistor is necessary.
