• Dolby B-NR × 2 channel
• Music sensor × 1 channel
Features
• Different type of PB equalizer characteristics selection (normal/chrome or metal) is available with fully
electronic control switching built-in.
• 2 type of input selection (radio/tape) is available.
• Changeable to forward, reverse-mode for PB head with fully electronic control switching built-in.
• Available to change music sensing level by external resistor.
• Music sensing level selection is available with fully electronic control switching built-in.
• Available to change frequency response of music sensor.
• NR-on/off and REC/PB fully electronic control switching built-in.
• 4 type of PB-out level.
• Available to allow common PCB designs with HA12173 series.
