An unquestioned long-term standard, D Series amplifiers are found everywhere in the lab, on the road, in public facilities, in the studio and at home. With over 25 years of continual production of the DC-300 amplifier, the D Series is an example of Crown's commitment to developing long-term, reliable amplifier technology.

The D-45 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.

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.

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 exceed the audio specifications for digital compact discs (CDs)

High damping factor provides exceptional loudspeaker motion control

Convection cooling system dissipates heat through the heat sinks and chassis for optimal cooling and maintenance-free operation

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

Three-Year, No-Fault, Fully Transferable Warranty protects your investment and guarantees its specifications
