2. Closed-loop Gain (f=1kHz)

• Closed loop voltage gain

• Playback amplifier gain

in low frequency

in high frequency

• Recording amplifier gian

3. Oscillation

When the closed-loop gain of amplifier is lowered, oscillation with occur. So the circuit

should be compensated by connecting of 10pF between pin 3 and pin 2, and 0.03 ㎌ in

series with 10Ω to the load end.
