Longevity of design


Recommended Posts

  • Members

Anybody know of any equipment items that have been in service for a long period without significant design change? I'm thinking along the lines of the SM58 which seems to have been around forever in the same basic design. Any other items that come to mind? Things change so fast, it's nice to see something that sticks around.

Around here, we regularly listen to a record player that was designed in the mid 70s, and occasionally listen to 78s on an old, all-in-one player that was built in the 40s.

 

If you go and pick up a new turn table, you can find all kinds of fancy stuff, but the inexpensive ones are more or less the same things that were coming out in 1980, as far as I can tell.

The QSC RMX1450 and 2450 have been around for a decade now with no changes. Not the longevity of the SM58, which may take the prize as far as mass produced consumer pro audio, but an unchanged 10 year run of anything pro audio is pretty good.

Good point, those amps seem to share an "Industry Workhorse" reputation just like the 58.

The Shure 55SH with a 3pin XLR connector seems to have settled down for quite a while.

 

Also the Switchcraft 1/4 in phone plug and jack

I use the Switchcraft Part number 11

The Jensen Transformer has been around since the 70s

Kinda funny, I was just talkin' to a friend of mine who retired out of the sound industry 15 years ago (he was head honcho at a couple different Casinos) and he was telling me that QSC amps were about Behringer grade back then reliability-wise. The RMX line really was a huge step up for QSC :) .

Really? I thought they had a history of being solid, but were just under the radar a bit compared to Crown.

The A&H Mixwiz is another iconic one. Although on the 3rd iteration, it's still very similar to at least the 2nd version in terms of look and layout. I tried to find information and pic of the original mixwizard but couldn't find anything.

 

Version 1 - 1997

Version 2 - 1998

Version 3 - 2004

 

Article on current version when it first came out in 2004.

I think pre-RMX they were 4 ohm min load? And no clip limiters :freak:. Crown and Crest were king back then at the pro level I think? I'd take Peavey over either of that era just for the DDT :D .

MX series surfaced in the 80s and were stable at 2 ohms. I have some 17 year old MX3000s that are still out there doing dusty festivals.

I agree.

 

QSC was every bit as professional and reliable as anything that Crown and Crest had to offer. And, in fact they were as reliable and maybe even more reliable. I still see plenty of MX's, Series 1's and USA's doing duty in movie theatres 12 hours a day, 365 days a year. I certainly don't see as much Crest or Crown doing this however and some of Crest's late 70's - 80's designs were horrible reliablity-wise. Thinking 3501's and FA's.

 

Also, the 1850/2450, etc. is a revision of the MX's and the smaller RMX's are revisions of the Series 1/USA. The schematics are "identical" in every meaningful way. The packaging is, however better as is the feature set.

Could have been his personal opinion and/or a right coast thing :D . He just rented a "K" setup for a gig he played a couple weeks ago (I was busy) and was asking me about them as his own knowledge about QSC products was from back then. Anyways I steered him away from buying K-Subs towards PRX618S-XLF's.

It took QSC a long time to become accepted by the national act/touring market. Their first shot at it was the EX series but it didn't fly. They finally hit paydirt with the Power Lite series. I can see someone confusing general quality with the long lag time it took for them to break this market.
