It is a digital amplifier that uses "MAX9744" for the power amplifier IC. With a built-in electronic volume, there is almost no left-right deviation, and the power supply can be used in a wide voltage range of 4.5 to 14V. With the high efficiency unique to digital amplifiers, it is possible to take out a large output of 20W + 20W without attaching a radiator. It is very easy to use with the filterless operation that suppresses unnecessary radiation noise by the pectrum diffusion method and the pop-up noise suppression function.
The power amplifier IC and chip parts are already mounted on the board.
Convenient with a mini jack. It can be used immediately with a compact player.
Prepare a power pass capacitor and a pattern for parallel addition.
The main parts are already soldered. Solder only input system parts (input C, resistor) that are easy to change.
Hole position where Takachi Denki Kogyo case LC135H is easy to use.
