1. The headphone amplifier’s output power and distortion are rated using the nominal capacitance shown. Larger capacitance
Notes:
reduces the ripple on the internal amplifiers’ supplies and in turn reduces the amplifier’s distortion at high output power levels.
Smaller capacitanceNmotaeysn: ot sufficiently reduce ripple to achieve the rated output power and distortion. Since the actual value

5. The value of RL, a current-limiting resistor used with electret condenser microphones, is dictated by the microphone cartridge.
6. The negative terminal of the microphone inputs connects to the ground pin of the microphone cartridge. Gain is applied only to the positive terminal.
