Crown Audio Retires Its D Series Power Amplifiers

Harman’s Crown Audio in Elkhart, Ind., announces that after 37 years of continuous production the company is discontinuing its D Series power amplifiers.

“Little did the 1977 engineering development team know that the new D75 would turn out to be the longest running product of the company,” says Tom Szerencse, Manufacturing Engineer, Harman Professional Amplifier Business Unit. “During its lifetime over 100,000 were produced. Generations of dedicated assembly personnel have touched the D75 and contributed to its long life. It epitomizes the focus we have to do our best and satisfy our customers.”

The Crown D Series evolved from modest beginnings. “In 1977 we developed the D Series from the Crown SA20-20, a one-rackspace 20 watt per channel solid-state stereo power amp that was an accessory to the Crown tape recorders of the time,” says Gerald Stanley, Director of Research, Harman Professional Amplifier Business Unit. “However, when mounted in a rack, the tape recorders and their electronics left little room for accessories, which shaped the compact form factor of the D Series and the rackmount-ability of Crown amplifiers ever after.”

The Crown D Series soon became used in the studio, onstage, in broadcast facilities, in fixed installations and even in homes. Models like the moderate-power D-75A and D-45 were ideal for applications like recording and broadcast studio near-field monitoring and small paging systems. The DC-300 was in production for more than 25 years.

“If any amplifier line should receive a lifetime achievement award, it’s the D Series,” Stanley adds. “The Crown D Series has outlived most amplifier companies, let alone most amplifier families.”
