Our Guide to Crown's DriveCore Amplifier Technology

The trailblazing technology inside CrownDCi, ComTech, XLS and iTech HD Series amplifiers

Building on Crown's legacy of innovation, DriveCore™ Technology decisively separates Crown amplifiers from everyone else. Based on breakthroughs by Crown's Gerald Stanley, Crown teamed up with Texas Instruments and their silicon design to seamlessly integrate the amplifier drive stage into the power output stage and put everything onto one very tiny chip.


The result is cutting-edge energy-efficiency, long-term reliability, greater accuracy, reduced weight and size and best-in-class signal-to-noise performance. This proprietary hybrid analogue-digital integrated circuit is protected by multiple patents - the product of two decades of R&D.

DriveCore™ features across the DCi DriveCore, CDi DriveCore, DSi DriveCore, ComTech DriveCore, XLS DriveCore and iTech 4x3500 HD product ranges, and clearly demonstrates why Crown continues to be the undisputed leader in sound amplification. Find out more about DriveCore™ and the products it's used in below.

By reducing the part count by over 500, DriveCore™ Technology greatly reduces design complexity compared to that of traditional amplifiers. That makes DriveCore™ amps more efficient and more reliable than those of competitors.

Simply put, a 4x600W DriveCore™ amplifier can be used anywhere and outperform existing amplifier technology by delivering more than twice the power while using just half the space of a 4x250W amp. 

For such a small chip, DriveCore™ provides huge audio quality dividends too.

For example, the patented feedback and PWM modulation circuits for fast recovery on peak transients, accurate reproduction of low-level detail, and precise tracking of low frequencies at all power levels for the unrivaled performance expected from Crown. The front-end drive circuits leverage the inherent efficiency of Class D output stages while also maintaining superb sonic characteristics.


The extremely wide tolerance for AC line conditions means whether you’re on a normal power grid or fluctuating back-up generator power for Life-Safety systems, DriveCore™ amps deliver sound that’s never compromised.


The end result is an ultra-efficient, one-piece audio amplifier circuit exhibiting the exemplary audio quality of a highly evolved Class AB design, giving you:

• Signal-to-noise in excess of 120db

• Total Harmonic Distortion less than 0.001%

• Efficiency greater than 90%

• Amp Scalability from 20W to 20kW

Perfection doesn't happen overnight.

Crown have been developing and refining amplifier technology since 1967, when they introduced the world’s first reliable, high-powered, solid-state amplifier, the DC 300. And a relentless commitment to constantly push the limits of sound, and the technology to deliver it, remains unwavering. 


Led by the engineering genius of Gerald Stanley, Crown's Vice President of Research and Development, Crown’s reputation for technical prowess is world-renowned. Gerald holds 31 patents in the U.S. alone, and his influence continues on our revolutionary DriveCore™ Technology, which features five patents applying to the advanced feedback, modulation, and output stage capabilities.
