Four-channel-mixer circuit | Next Electronics

This device prevents paper notes and memos from being overlooked. A paper note placed between two fingers made of a conducting material (metal or conductive plastic) breaks the circuit, allowing pair 1 of Ul-a to go high. This causes Ul-c...

150W MP3 Car Amplifier

A diagram of an active loudspeaker. The LF353 from National Semiconductor will split the audio signal into three bands. The SANYO LA47536 will amplify these signals. In stereo mode, eight high speakers will create significant sound pressure. The LF353 is...

Audio Subcarrier Oscillator

A single integrated circuit (IC) provides all amplifiers: the 74HC04 Hex Inverter, which is a digital component. The second oscillator synchronizes to three times the frequency of the first oscillator, thereby tripling the frequency modulation (FM) deviation. Utilizing the lower...

mixer

An electronic project detailing a D.C. mixer for synthesizers and various control applications. The D.C. mixer circuit is designed to combine multiple direct current (DC) signals into a single output, making it particularly useful in synthesizer applications where different control voltages...

audio mixing

The fundamental principles of mixing audio signals are simple, yet they are often not clearly explained online. This article aims to address those gaps. Mixing audio signals involves combining multiple sound sources to create a cohesive audio output. The process requires...

6G2 amp volume and tone play up on one input only

A newcomer is seeking a welcoming environment and expresses a desire to share a considerable amount of information. In the context of electronic schematics, it is essential to facilitate an inclusive environment for individuals at all levels of expertise. This can...

Audio Mixer with one transistor

This single transistor audio mixer is utilized in an amplifier circuit design featuring a base-driven transistor, where the emitter is current-controlled. The majority of the driving current flows through the collector. This audio mixer circuit employs a single transistor to mix...
