Описание

The D-45 and D-75A are 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.

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.

Your dual-channel (stereo) amplifier can optionally be configured to deliver double the power from a single (mono) channel. It also provides the following features:

  • 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.

  • Mounts in a standard 19-inch (48.3-cm) rack.

  • Front-panel headphone jack.
