Crown CT475 4-Channel Rackmount Power Amplifier (75W/Channel @ 8 Ohms)
Crown CT475 – 4-Channel 75W ComTech DriveCore Rack-Mount Amplifier
Product Overview
The Crown CT475 is a four-channel, 75-watt-per-channel ComTech DriveCore installation amplifier designed for commercial AV applications requiring multi-zone background music, paging, and distributed audio in a compact 1U chassis. Part of Crown's ComTech DriveCore series, the CT475 is suited for conference rooms, corporate facilities, hospitality venues, and commercial spaces requiring multiple independently driven audio zones with 70V and 100V constant-voltage support.
Product Description
The CT475 delivers 75 watts per channel into 8 ohms across all four channels with 70V and 100V constant-voltage output for distributed speaker systems and 4-ohm low-impedance operation for direct-drive applications. Crown's DriveCore technology integrates driver and output stages for improved thermal efficiency in the 1U rack chassis. Four independent channels allow zone-specific level control for multi-zone background music or paging systems. The amplifier includes comprehensive protection circuitry covering DC faults, thermal overload, and short-circuit conditions on all four channels.
Key Features
- Four independent channels at 75W/8Ω — Multi-zone audio from a compact 1U chassis for conference rooms and commercial spaces.
- 70V/100V constant-voltage output — All channels support distributed ceiling speaker systems.
- Crown DriveCore technology — Integrated IC for thermal efficiency in enclosed commercial rack installations.
- 1U rack-mount chassis — Space-efficient form factor for equipment racks in conference rooms and commercial facilities.
