    Crown DC 300 Enters TECnology Hall Of Fame

    I thought this announcement on Crown's web site appropriate to post here on Crown's 60th Anniversary. Thanks Gerald!

    http://www.crownaudio.com/gen_htm/press/pr157.htm

    NEW YORK CITY - November 2007 -- As a fitting cap to Crown International's 60th anniversary year, the DC 300 amplifier, first introduced 40 years prior in 1967, was inducted into the TECnology Hall Of Fame on the opening day of the 123rd AES Convention in New York City. Gerald Stanley, Crown International's senior VP of R&D and the original designer of the DC 300, was on hand to accept the award.
    Presented by the Mix Foundation for Excellence in Audio, best known for its production of the TEC Awards, and hosted by the AES, the Fourth Annual TECnology Hall Of Fame ceremony was emceed by George Petersen, executive editor of Mix magazine and director of the TECnology Hall Of Fame.
    Petersen prefaced Crown's award by remarking, "[The DC 300] was a classic that really ushered in and defined the era of the modern power amplifier. And 1967 was a perfect time for this product to come out. Suddenly there were rock concerts that were high SPL--very loud--and needed great amplification. Live sound systems were coming into vogue. Listening levels in recording studios in 1967 started going through the roof and somebody needed to produce an amplifier that was loud enough to take care of this. And even 40 years after its introduction, there are so many of these DC 300s still in service, it's an amazing testament to Crown reliability." (more...)

    There's one lying dormant here, just waiting to find its Special Purpose. It's a little newer than Krunchy's pic, but not a whole lot. It got nudged aside by a Urei 6260.

    Q on the amp - a touch out of topic

    Bonjour Stéphane,
    I remember seeing your system in the NRDS, at the time you were using a passive network. Seems like you have moved to active filtering, is this the case? If so, I'd be interested to know how you are rating the noise (or silence!) from your amps in this configuration. I'm hunting for an amp that would be quieter than what I use today (a simple small Trends TA-10) fro my mid-high, I see so many of you with amcron that I am tempted, only I am wondering if they would be quieter or not.

    I'm sitting about 3m away and when no musinc is playing can hear the faint hiss from the amp, it's not worrying much as it's not a buzzing sound, more like tape hiss, so not intruding, still I'd be interested in something 'quieter'.

    Merci pour l'information,

    Scorpio - en fait Stéphane également,
    Bonsoir!

    Greetings, All,

    I have an old Crown DC-300, and it still works very well. However, it does produce a hum, which I would love to have removed. I also have a Crown VFX-2A electronic crossover, which also could use a "tune up". Can anyone recommend someone on the Left Coast that goes through older amps and components like my Crowns, and get them back to original spec? Many thanks for any comments, suggestions, or advice! Take care, and God Bless!

    Every Good Wish,
    Doc

    In it's day the DC300 reigned supreme! In those days Crown was building
    elaborate shiney metallic looking reel to reel tape recorders too. I had the catalogs but never actually saw one anywhere.

    Morning, John,

    Thanks for the note. Yes, I remember those days well! If a band back then had Crown amps, they were in the "big time", and other musicians looked in awe at those large Crown amps, and could hardly wait for the day when they, too, could afford to own some!! I still like my old DC-300, and am now considering getting a few more of them. I don't think I really need the mega-watt monsters that others need in their home theatre systems, and a couple of good, solid, quiet Crown amps should do me nicely! For quite a few years, I used a couple of 4.5 cubic foot boxes, with some cast frame, Eminence 15" woofers, and my JBL 2420's, with the proper JBL horn lense assemblies, for my home stereo. Yes, it could have used a bit more top end, and the bass rolled off under 45HZ. But, I'll tell you, it was a very musical sounding, sweet system, and I could blow the glass out of any apartment I live in, with only a few watts from that old Crown DC-300!!! It idled, most of the time, and did very well, indeed. So, I think with at least one more of the, plus my two Harman Kardon, high current capable amps that I use now, I should be in Fat City!! So, I have my feelers out for a good Crown DC-300A, or maybe a pair of them. Looks like you can get good ones for WAY under $500, and that's good, too! Thanks, again, for your note, and I'll post an update as my plans come to fruition. Take care, and God Bless!

    Every Good Wish,
    Doc

    Doc,
    You might want to consider spending a bit extra in shipping and send the Crown home . . . to Elkhart, Indiana! Crown no longer works on the legacy amps at the factory, but http://aetechron.com is their "official factory service point" for the old stuff and is staffed with experienced Crown people.

    Hey, BMWCCA,

    Many thanks for that outstanding suggestion, and for the info on getting in touch with those folks! Sounds like just the proper course of action. I'll let you know how it all works out, when I've contacted them, and have an idea what to do next. Thanks, again!! Take care, and God Bless!

    Every Good Wish,
    Doc

    Greetings, Friends,

    Well, I decided to stick my toe into the deep waters of buying a Crown DC-300A on FleaBay! Did the deed today, and at $349, may have paid a little more than I have seen others going for. But, the one I decided upon looks much nicer than most of the others, and the seller had very high positive feedback, so I went ahead and took the plunge!! The "new" Crown should arrive in just a few days, and that will be fun! I'm hoping to use it for whichever subwoofer system I end up building first: 1 - a pair of 2235H's, in 4.5 cubic foot boxes, tuned properly, electronically crossed over at 90HZ; or, 2 - a single 2242HPL, in an 8 cubic foot enclosure, tuned properly, and crossed over in the same manner, and at the same frequency. If I use the 18" JBL, I'll run the "new" Crown in it's bridged mode, and that should be MORE than enough power for the listening I usually do!! I know that, whichever system ends up being built first, either one of them will SMOKE my current subwoofer "system", which ain't much, in truth!! Great for low level listening, but horrible if you ask too much SPL from it!!

    I'm thinking about going for one more nice Crown, if one pops up, and then go from there. I'm also thinking about adding a second Crown VFX-2A crossover to the one I already have, and then maybe doing a three-way system, added to the Audio Control electronic crossover that my sub uses. Hummm.......!!??!! I also still have my old, original Crown DC300, and have contacted AETECHRON about going through it and cleaning it up a bit. Sounds like they are good folks over there!

    Thanks for all the great info on this site, Friends! It's a pleasure to dig around for the myriad gems to be found here!! Take care, and God Bless!

    Every Good Wish,
    Doc

    Hey, Guys,

    My "new" old Crown DC-300A arrived today, safe and sound! The seller shipped it, from Las Vegas just yesterday, so that is about as good as it gets in quick shipping!

    The bad news is that this amp is dinged up a bit more than I'd hoped, and the cap on the power supply coil is dented in a good bit. Oh, well.... The good news is that it does, indeed, work, and I'm running my two "subwoofers" with it, right now! Seems to be pretty balanced, one channel to the other, and it sounds very smooth, and almost "sweet". But one interesting thing has popped up: My old Harman Kardon HK870, 100WPC power amp, is actually LOUDER than the Crown, which is has more RMS power!! How about THEM apples????!!!! The HK amp is "high current capable", which means it can put out far more than it's rated power, for those brief transients that needs more juice. I don't know what it's power ceiling is. But, the Crown, if I remember correctly, puts out about 178 watts per channel, before it gets into clipping trouble. No clipping from either amp, but the HK is definitely a little bit louder than the DC-300A, which I find very interesting! I'm going to test it further, in a few days, with some Pro Sound Reinforcement gear, and see how loud the Crown actually can play. Right now, it's doing well, and isn't even warm yet, even though it's been playing for a bit, now.

    Any thoughts about this interesting anomaly? Also, I have never used such an amp in it's bridged/mono mode, and I have no paperwork with this "new" Crown. Any suggestions would be appreciated! Thanks, very much, Gentlemen, and God Bless!

    Every Good Wish,
    Doc

    Lots of "paperwork" for that amp here:
