REC equalizer
Line Amp.
ALC (Automatic Level Control)
MS (Music Sensor)
Each electronic control switch to change REC equalizer, bias, etc.
REC mute
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
