Switchless Rec/PlayBack Amp for VCR
Features:
D Contians all recording/playback amplifiers required for VTR audio signal system.
D Capable of setting each mode of recording, playback an muting by changing only the control
pin voltage
D Very small pop noise occurring at the time of mode selection
D Easy to adjust recording level, playback senisitivity
D Improvement in reliability due to electronic switch
