2.1 amplifier schematic built around the TDA7294, by Technical Mriganka, in a 219 KB PDF. The TDA7294 is a DMOS audio amplifier IC running from dual supply rails, frequently used for higher-power subwoofer and stereo channels. The drawing helps trace mute and standby pins, feedback parts and supply decoupling during build or repair. Confirm rail voltages against the datasheet limits and the speaker load, and provide adequate heatsinking.
