Crown Audio CT875 Eight-Channel 75W Power Amplifier

Crown Audio CT875 Eight-Channel 75W Power Amplifier

The CT875 delivers remarkably clean amplification in an extraordinarily compact 1RU chassis with no cooling fan required. Built on Crown's proprietary DriveCore™ technology, this eight-channel amplifier achieves over 90% efficiency while maintaining the sonic character of a Class AB design. Its convection-cooled construction and light 10 lb weight make it ideal for installations where space and thermal management are critical constraints.

Amplification & Power Delivery

Each of the eight channels produces a rated 75W output at both 4 and 8 ohms, with exceptionally low distortion of less than 0.05% THD and intermodulation distortion. The amplifier remains stable across 2–16 ohm load impedances, providing reliable performance across a wide range of speaker configurations without requiring external transformers for standard applications.

Design & Connectivity

The CT875 features balanced 3-pin barrier block-type line inputs for professional audio routing and 4-pin Phoenix-type speaker outputs for secure, field-serviceable connections. Its universal power supply accommodates international voltage standards, while the 15A IEC connector and idle power consumption of just 23.0W reflect its efficient, low-footprint design philosophy.
