About

 

Prelude is a small company that reflects three of my greatest passions: electronics, software, and audio.

Electronics is part of a family tradition that I continued by earning a degree in Electronics Engineering. Over time, while working for different companies, I developed a strong passion for software development and learned how to build applications that solve real-world problems.

Audio is a natural extension of my life as a musician. After years of playing and listening, I learned that music must be experienced through high-quality equipment to fully appreciate the details of a recording and to truly understand the artistic vision of the musician who composed it.

At Prelude, we develop our products in Costa Rica, driven by passion and dedication. Our team is very special—carefully selected to create products that are reliable, well-crafted, and worthy of the trust of our customers.

 

 

 

 

 

 

 

 

 

Audio

Because real music  deserves real definition

“The music you like has to be played in a Hi-Fi equipment with full range frequency response, high gain and low harmonic distortion. Let us design the amplifier, speakers or crossover you need to listen to what you like.”

  • Passive speakers
  • Active speakers 
  • One, two or three ways
  • Active subwoofers

  • Passive crossovers
  • 1, 2, 3 and 4 order
  • Active crossovers

  • Analog Class A transistor audio amplifiers
  • Analog Class A vacuum tube audio amplifiers
  • Analog Class AB audio amplifiers
  • Digital audio amplifiers

Electronics

“Control a process, a machine, a signal or a sound does not have to be expensive or complex. We have different solutions for your project. The electronic circuit that you need in the time you need it … is our task. We design your circuit with all the corresponding verification processes.”

What makes our software unique

“A Website is more than a tool, it represents you to others, so designing it with your ideas and needs is important … but managed by someone who knows how to show them”

All the projects we work on are developed from scratch. We do not maintain or improve legacy projects, this is because we have photographers, designers, UX and UI engineers to help you up with the pictures, logotypes and others to build your website.

We are not an outsourcing company, we are a business that offers different services, we believe that quality, performance and details are more important than volume. And that cannot be achieved if we have many projects at the same time.

Application ares:

  • Websites.
  • Desktop.
  • Automation.
  • Architecture.
