Good news for all audio enthusiasts: we are proud to present yet another all-analog circuit developed entirely in house. Despite the simple design of this audio power amp with just one pair of transistors in the output stage, Q-Watt can deliver over 200 quality watts into 4 ohms with...

M5Stack ATOM ECHO is a tiny programmable smart speaker. Its design is based on the M5ATOM series of products. The slim design has a dimension of 24x24 and is 17mm in height. Its premium finish gives it a professional look and makes it easy to carry anywhere. M5Stack ATOM ECHO can be...

The EVAL_AUDAMP24 e-mode GaN HEMT-based evaluation board from Infineon Technologies is a 2-channel, 225W/ch (4Ω at ±43V) or 250 W/ch (8Ω at ±63V) half-bridge class D audio power amplifier for high-end Hi-Fi audio systems. This evaluation board demonstrates how to use the IGT40R070D1...

The project published here is based on SSM2019 IC which is a latest-generation Pro audio preamplifier. A female XLR connector is provided to connect differential Micro-phone. Circuit also provides Phantom power input, combining SSM preamplifier design expertise with advanced processing....

An open source universal audio amplifier called ‘U-AMP‘ @ GmanModz, that is available on GitHub: Using what I learned getting digital audio working on each systems, I set out on a new project I would call “U-AMP” (Universal-Amp). This would be ONE pcb which has the features of...

With a smartphone or an MP3 player it’s easy to play audio files, but generally not at room strength or if you can, only in wretched quality. The Card Sound project makes it possible to fill the room with music and have excellent sound reproduction! This lightweight and compact player...

The project described here is a compact stereo volume and balance control with rotary encoder. It provides 32 log potentiometer steps with buffered wiper output. The project can easily replace mechanical potentiometer. 5 LEDs indicate the volume level or balance settings , depending on...

USB powered mini speaker amplifier is conveniently powered by USB and it is simple to set up. USB powered speakers are convenient for listening to your media while at home or on the go. Conventional computer speakers that require an electrical outlet to work can be prohibitive because...
