Technology
Class D and Class I amplifiers are notable for extraordinarily high
efficiency and being well suited for driving difficult reactive loads such
as subwoofers.
Crown engineers developed DriveCore™ Technology – a proprietary
hybrid analog-digital integrated circuit (IC) developed with Texas
Instruments that drives the “front end” of the Class D or Class I output
stage. Over 60 years of Crown’s design knowledge and experience
went into the development of this technology resulting in truly
remarkable benefits.
DriveCore™ Technology provides an extremely wide-tolerance with
regards to sagging or “dirty” AC line conditions providing consistent
performance without affecting audio quality. This means that your
performance will not be compromised by fluctuating generator power
or overloading by lighting rigs, backline gear, etc.
In addition, DriveCore™ Technology’s patented feedback and PWM
modulation circuits enable fast recovery on peak transients, accurate
reproduction of low-level detail, and precise tracking of low-
frequencies at high power levels for maximum subwoofer output.
