Overview

The D-75A power amplifier is perfect for moderate power applications such as recording or broadcast studio near-field monitoring, video suite audio monitoring, a recording/broadcast headphone amp or a small paging system.

Crown's AB+B circuitry ensures efficient use of output transistors while incorporating protection against shorted, open, mismatched or low-impedance loads.

Designed, built and carefully checked to ensure reliable operation with a wide variety of loads, Crown D Series amplifiers are convection cooled. Their high reliability is particularly important in reducing maintenance costs. The rackmountable D-75A is an example of Crown's commitment to developing long-term, reliable amplifier technology.

All D Series amplifiers are covered by Crown's comprehensive Three Year No-Fault Full Warranty. This warranty protects your investment no matter what happens to your amp even if it's damaged by accident! This totally transferable warranty also guarantees that your amp will continue to meet or exceed all original specifications.

FEATURES

Your dual-channel (stereo) amplifier can optionally be configured to deliver double the power from a single (mono) channel 
Powerful AB+B class circuitry yields maximum efficiency with minimum crossover "notch" distortion
IOC (Input/Output Comparator) alerts of any distortion that exceeds 0.05% to provide proof of distortion-free performance
Signal presence indicators verify the presence of amplifier output
Detented level controls for precise repeatability
Ultra-low harmonic and intermodulation distortion result in the best dynamic transfer function in the industry
Very low noise and wide dynamic range
High damping factor provides exceptional loudspeaker motion control
Convection cooling system eliminates fan noise and maintenance
Three Year, No-Fault, Fully-Transferable Warranty completely protects your investment and guarantees its specifications
