Continued to next page. Unit (resistance: Ω) Inputs the Line Amplifier output signal. The ALC level is set by the resistors R1 and R2. Output inpedance → 50Ω (typ) Inputs the recording signal from Line Amplifier. The recording current is set by the resistors R1 and R2. A coupling capacitor is unnecessary as pin 15 is a zero baias input. Used to adjust the high-region peaking frequency during recording amplifier in LP mode. On resistance → 15Ω (typ) Intput inpedance → 50Ω (typ) Recording amplifier negative- feedback input. Used to adjust the high-region peaking frequency of the recording amplifier with an L, C, R network connected to ground. Output inpedance → 40Ω (typ) Ripple rejection is performed when connected to GND through an electrolytic capacitor for the filter. VCC max=14V VCC=8.5V to 12.75V When the voltage on pin 21 is 3.6V to 6.0V:EP; when 1.8V to 2.6V:LP; when 0V to 1.8V:SP Switch On Pin Number EP mode:4,5,16 LP mode:16 Inputs EE and RE signals. The reference input is set by resistors R1 and R2.The amplifier gain is fixed at 21.5 dB. In addition, because the input impedance is as high as 110k Ω, a 0.1 µF ceramic capacitor can be used for the coupling capacitor on pin 12. Internal reference Power supply of each circuit block |
