With almost half a decade worth of experience as a mechanical engineer in the mechatronics field, I can confidently say that I've amassed an extensive knowledge base that correlates well with your project's requirements. Among my core proficiencies is PCB design, which I've specialized in through the use of Altium Designer over several projects. This software allows me to execute an effective circuit design for your high-power audio amplifier.
Having worked on various projects with different complexities, I've had the opportunity to design both single/double-sided and multi-layer PCBs layouts, a skill that would prove invaluable in this particular project. My range of work includes producing schematics for data and control interfaces such as UART, USB, SPI, etc., which aligns well with your need for purely analog inputs. Moreover, I've successfully designed circuits for digital audio and multimedia interfaces like HDMI,e.t.c.
I believe my background in circuit design, mastery of electronics and proven ability to work on high-powered audio amplifiers make me an obvious choice for this project. Let me help transform your idea into a functional 3D model ready to be manufactured efficiently. My commitment to customer satisfaction is steadfast - exceeding your expectations is always my goal.
