About HyperVolt Electronics
Who We Are
At HyperVolt Electronics, we don’t just build electronics—we engineer performance. From high-power Class D amplifiers to custom electronics design, we create solutions that deliver power, precision, and innovation.
Based in Johannesburg, South Africa, we are one of the few local companies designing and manufacturing professional audio technology in-house. Our expertise covers the full spectrum—design, prototyping, manufacturing, and upgrades—allowing us to take a project from concept to reality under one roof.
We’re known for our V-Series Class D amplifiers, capable of delivering up to 5000W per channel with custom-built Switch-Mode Power Supplies (SMPS) ranging from 2000W to 6000W. But our work goes far beyond amplifiers. We convert, repair, and upgrade existing gear, design custom PCBs and circuits, and develop embedded systems with intelligent microcontroller programming for smart, connected audio solutions.
What We Offer
- Professional Audio Solutions – High-performance Class D amplifiers and SMPS power designs.
- Upgrades & Conversions – Transforming older amplifiers into efficient Class D powerhouses.
- Repairs & Servicing – Precision diagnostics and component-level repairs.
- Custom Electronics – PCB and circuit design for any application.
- Prototyping & Development – From idea to fully functional product.
- Smart Integration – Embedded systems and firmware for intelligent control.
At HyperVolt, every product and service is driven by engineering excellence, attention to detail, and a passion for sound. Whether you’re a DJ, sound engineer, installer, or electronics innovator, we deliver solutions built to perform and made to last.
