Crown D-45
Product Description
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 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. Specifications
