Electronics enthusiast since childhood, musician, and longtime engineer, I design and build electronic devices combining analog audio, embedded systems, and practical everyday innovation. My background includes: IT systems & network engineering analog audio electronics microcontroller and robotics projects studio recording and live sound for more than 10 years Today, through AAL (Analog Audio Lab), I develop DIY and boutique electronic solutions ranging from audio devices and signal conditioning tools to smart everyday electronics designed for reliability, simplicity, and real-world usefulness. https://www.lectronz.com/stores/aalab Custom RSS Generator https://lectronz-images.b-cdn.net/lectronz/active_storage/representations/proxy/eyJfcmFpbHMiOnsiZGF0YSI6NzA5MDEsInB1ciI6ImJsb2JfaWQifX0=--24db305a091229e243123b970faa22444cbeaf68/eyJfcmFpbHMiOnsiZGF0YSI6eyJmb3JtYXQiOiJwbmciLCJyZXNpemVfdG9fbGltaXQiOlsxOTIsMTkyXSwic2F2ZXIiOnsic3RyaXAiOnRydWV9fSwicHVyIjoidmFyaWF0aW9uIn19--0808b744be7c555ce58430d0ed7115f4f35a0403/AAL_logo_profil.png https://www.lectronz.com/stores/aalab Passive parallel mains noise filter for audio and sensitive electronic equipment Fri, 02 Oct 2026 05:27:18 +0000 https://www.lectronz.com/products/aal-parallel-emi-rfi-filter-v2 https://www.lectronz.com/products/2304 Analog active subwoofer crossover with selectable frequencies, XLR/RCA I/O and independent sub level control.
