(Notes)
1. The electronic select switch level is approximately (VCC–0.9)/2.
2. REC amplifier NF parameters Z1 through Z3 should be selected to accommodate the recording level and frequency
response that will be required in metal/normal tape and normal/higher speed modes.
3. Z1 through Z3 may be configured with coil “L”, capacitor “C”, and resistor “R”.
4. The electronic select switch mode illustrated above shown no VCC being impressed on Me/Nor SW or Nor/High
SW.
5. The ALC level on pin 7 should not be changed over while VCC is impressed.
No. 2564-5/15
