Headphones with Noise-Canceling Feature

The project produces noise-canceling headphones which allow the background noise to be minimized while listening to music.

Audio Mixer with 3-Channel Input

The circuit was designed to provide an overall gain of one between the output and each input channel on an audio mixer with 3-channel input.

STK4050 Audio Amplifier with 200W Output

The project is based around the hybrid integrated circuit STK4050 manufactured by Sanyo to build a low noise mono audio amplifier with complete high quality.

Graphic Equalizer with 5-Band Capability

The circuit is based around Monolithic Linear SANYO integrated circuit LA3600 to create a low noise and completely high quality 5-band graphic equalizer which can be used for any portable tape recorders, component stereos, radio cassette recorders, car stereos, etc.

MOSFET Audio Amplifier with 60W Output

The circuit was designed to produce high quality and powerful audio amplifier that would provide 60W-90W power output.

Mini Amplifier with 2 Watts Output

The objective of the design is to build an amplifier circuit that can be contained in a small loudspeaker box while producing a power output of 2 Watts.
