Frequently asked questions
Which is better for a small venue with four main speaker zones?
The CT4150's four 125W channels directly match this need, providing robust power per zone without unused amplification.
Which works better for a large building with many distributed speakers?
The CT875's eight 75W channels let you power more independent zones or speaker pairs, making it ideal for offices, retail, or hospitality installations with numerous speaker locations.
Is there a meaningful sonic difference between the two?
Both use identical DriveCore™ technology, Class AB character, and achieve <0.05% THD with 110 dB SNR—the difference is amplification architecture (four powerful channels versus eight moderate channels), not tone quality.
Do both fit standard rack installations?
Yes—both are 1RU chassis, weigh 10 lbs, use convection cooling with no fan, and support universal voltage, making them equally compact for pro installations.
