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 · REC equalizer · Music sensor × 2 channel × 2 channel × 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. * Dolby is a trademark of Dolby Laboratories Licensing Corporation. A license from Dolby Laboratories Licensing Corporation is required for the use of this IC.

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.
