Crown Professional 40 WPC Stereo Power Amplifier (USA) D-75A

Crown D-75A Professional 40 WPC Stereo Power Amplifier (USA)

This American-made Crown D-75A is a compact yet powerful dual-channel amplifier that has undergone our Level One service and testing which should ensure many more years of reliable performance ahead. Known for exceptional reliability and ultra-low distortion, this professional-grade amplifier delivers 40 watts per channel into 8 ohms in stereo mode or 110 watts in bridge-mono configuration.

The D-75A features Crown’s advanced AB+B class circuitry for maximum efficiency with minimal crossover distortion, along with IOC (Input/Output Comparator) indicators that alert you to any distortion exceeding 0.05%. Signal presence indicators verify amplifier output, while detented level controls provide precise repeatability. The amplifier offers exceptionally low harmonic and intermodulation distortion, very low noise, wide dynamic range, and high damping factor for superior loudspeaker motion control.

Perfect for studio monitoring, broadcast applications, headphone amplification, or high-quality home audio systems, this single rack space amplifier is convection cooled for silent operation and maintenance-free reliability. The combination XLR/phone inputs accept both balanced and unbalanced sources, while barrier block outputs and a stereo headphone jack provide flexible connectivity options.
