PA system, home theater subwoofer, guitar amp. Power: ±35V to ±45V DC (dual rail). Output: 100W into 4Ω.

Connect Pin 2 to ground. Attach the center wiper pin of your 10k Ohm potentiometer to Pin 3. Connect one outer pin of the pot to your audio source input, and the remaining pin to ground.

Discrete transistor designs offer more control over signal fidelity and are excellent for learning biasing and frequency response practical audio amplifier circuit projectspdf

These manage the current flow, acting as the "muscles" of the amplifier to boost signal strength.

Used to control the amount of current and set the gain (amplification level).
