Crown Audio CT8150 Eight-Channel 125W Power Amplifier

Crown Audio CT8150 Eight-Channel 125W Power Amplifier

The CT8150 delivers eight channels of transparent, high-efficiency amplification in a single 1U rackmount chassis with zero fan noise. Its DriveCore™ technology fuses the drive stage and power output into a single chip, yielding the sonic purity of Class AB designs with the efficiency of Class D—over 90% efficient without compromise. Built for installed sound, live reinforcement, and distributed audio systems, this amplifier handles the real-world demands of professional deployments.

Architecture & Efficiency

DriveCore™ technology integrates the front-end drive circuits with Class D output stages, achieving exceptional efficiency while maintaining the audio characteristics of a fully evolved Class AB amplifier. The convection-cooled design eliminates fan noise entirely, critical for installations where silence between program material is essential.

Audio Performance

With a signal-to-noise ratio of 110 dB and distortion under 0.05% THD across the full bandwidth, the CT8150 delivers clean, articulate reproduction. Frequency response of ±0.5 dB and rock-solid stability across 2–16 ohm loads make this amplifier equally at home driving compact speakers or large-format systems.
