Features
Available to create characteristics of REC equalizer by changing external resistor, no coil
Equalizer volume is available to calibrate recording automatically with micro-controller
Electronic volume built-in is available to set the level of recording and play back automatically with
micro-controller
4 types of input (3 out of 4 are by way of electronic volume)
Input electronic control switching is irrelevant to REC/PB electronic control switching
Dolby noise reduction system is available with double cassette decks (Unprocessed signal output
available from recording out terminals during PB mode)
Log-compressed level meter output is range from 0 V to 5 V (Usable as music search switchable gain of
0 dB and 20 dB respectively)
Normal-speed/high-speed, normal/metal/chrome fully electronic control switching built-in
NR-ON/OFF, Dolby B/C, MPX ON/OFF fully electronic control switching built-in
Reduction of the number of pins by transfered serial data to electronic volume control switching and
another control switching (Controllable from micro-controller directly)
Small the number of external parts
