  • Page 31: Using Hiqnet Audio Architect

    Using HiQnet Audio Architect Crown CDi DriveCore amplifiers have Digital Signal Processing built in. When using a CDi DriveCore amp, the loudspeaker processing (crossovers, limiters, EQs, and delays) are in the onboard DSP, making discrete rackmount loudspeaker processing devices unnecessary. This drastically reduces setup time, commissioning, rack space, and costs.
