16 CIRCUIT OPERATION 1. VIDEO PART 1-1) EE MODE Video Signal which is output from RL902 is input to pin 37 of IC301 through OSD IC. It is amplified 6dB by AGC, then it is output to pin 34. This output signal is output to Video Jack through RL902 of RELAY IC.
17 CIRCUIT OPERATION 1-3) PB MODE When playing the tape, the signal which is picked up from the tape is amplified 50 dB. Then luminance signal goes to pin 11 and color signal goes to pin 7 through AGC. Luminance signal of pin 11 is input to pin 39 of IC301 through PB EQ cir- cuit in order to match playback characteristic.
18 CIRCUIT OPERATION 2. AUDIO PART 2-1) EE MODE External AUDIO signal which is input to pin 16 of IC201 is output from pin 22 of IC201 after being amplified through ALC and Line Amp. 2-2) REC MODE It will be the REC mode when REC 5V is input to pin 24 of IC201.
