Crown Audio CT8150 Eight-Channel 125W Power Amplifier
Description
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 live setups where silence between program material is essential and your mix stays pristine.
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 you'll hear on stage. 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, giving you confidence in any venue.

Reviews
At a Glance
The Crown Audio CT8150 is an eight-channel 125W power amplifier built into a single 1U rackmount chassis with zero fan noise, using DriveCore™ technology to deliver clean, transparent amplification for live reinforcement and distributed audio systems. Sound operators and live-sound techs rely on it for its 110 dB signal-to-noise ratio, rock-solid stability across any speaker load, and bulletproof reliability in venues and installations where silence between program material matters. Choose it when you need eight channels of transparent power in the smallest footprint without the hum or heat of traditional fan-cooled designs.
Frequently Asked Questions
How many watts per channel does the CT8150 deliver?
The CT8150 delivers 125W per channel across all eight channels simultaneously into 4-ohm or 8-ohm loads, with all channels driven at full power.
What makes the CT8150 silent compared to other rack amplifiers?
It uses a convection-cooled design with no internal fan, eliminating cooling noise entirely—critical for venues and studios where background hum during quiet passages ruins recordings and live sound quality.
What is DriveCore™ technology and why does it matter?
DriveCore™ integrates the drive stage and Class D power output into a single chip, achieving over 90% efficiency while maintaining the sonic purity and low distortion (under 0.05% THD) of Class AB amplifiers.
What speaker loads can the CT8150 handle?
The CT8150 is stable and rated across 2–16 ohm loads, making it compatible with compact speakers, large-format systems, and mixed speaker configurations in the same installation.
What inputs and outputs does the CT8150 provide?
It features 4 Phoenix input connectors and 4 Phoenix output connectors, allowing you to run up to four stereo pairs or eight mono channels from a single amplifier.
