Frequently Asked Questions
What is DriveCore™ technology and how does it benefit amplifier performance?
DriveCore™ integrates the amplifier drive stage into the power output stage on a single chip, combining the efficiency of Class D output stages with the sonic characteristics of a highly evolved Class AB design. This results in over 90% efficiency and >90 dB of gain with no compromise in audio quality or noise floor.
Is this amplifier suitable for live touring and venue installations?
Yes, the CT475 is designed for live performance, touring, and install audio applications. It is convection cooled (no fan), stable across 2–16 ohm loads, includes patented feedback and protection circuits, and fits up to 8x125W capability in a 1U chassis, making it ideal for mobile rigs and permanent installations.
What speaker impedances and configurations does the CT475 support?
The amplifier is stable for 2–16 ohm loads and supports standard line-level inputs. For 70V/100V distributed speaker systems, an XFMR 4/8 transformer is required and sold separately.
How does the CT475 compare to other professional power amplifiers?
The CT475 competes with models like the QSC RMX 850, Behringer NX3000, and Powersoft Ottocanali 415, offering professional-grade efficiency, low distortion, and transparent audio character in a compact, fan-free chassis suitable for touring and installation environments.
What is included with the CT475 and what might I need to add?
The amplifier comes ready for standard speaker connections and line-level audio inputs. If you plan to use 70V/100V distributed systems, you will need to purchase an XFMR 4/8 transformer separately.
