Crown

[Odd]

The Crown Audio plant, part of Harman Professional, announced it will close its Elkhart plant. (http://www.elkharttruth.com/hometown/elkhart/crown-audio-to-close-workers-affected/article_063e9621-e9b9-5b41-bd43-e543ce131779.html)

what a shame... I FEEL BAD FOR ALL CROWN LOVERS, MOVING PRODUCTION TO ASIA?

[Wayner]

You guys, it's not just Crown. Harman Pro is shedding itself of roughly half its employees. Closing locations associated with Crown, BSS, Studer and Soundcraft. Some people are being asked to relocate to "centers of competence" but this is a wholesale jettison of people across the board. Northridge is one of these CoC sites but around 2/3's of the development people there will be terminated. Suddenly a pool of extraordinarily talented audio engineers, and other professionals, has become available.

I'll only add that I'm restraining myself from going into a rant.

Sad, they were such nice folks to deal with for the past 50-years! Recently Crown had taken over distribution of JBL parts, too. I wonder if there will be a yard sale of all that "obsolete" stuff they have?
:crying:

I'll only add that I'm restraining myself from going into a rant.I bet. Good Luck! Very sorry to hear about this shortsighted decision, and am sorry for you too.

Centers of competence. Honestly I thought Elkhart was Harmans last center of competence.

I held out hope that Crown would remain at least to manufacture the mission critical I-TECH line in the US. It appears that my pending I-TECH order will come from Mexico. They are over three months late right now. I don't plan on following Crown out of the country.

Who's still making tour grade amps in the US?

I haven't looked yet but I don't recall Ashly or ATI making DSP touring grade amps.

My next might Linea Research. Started by some guys that left BSS when Harman aquired them. I had one to demo and really really liked it.

I wonder what the crew at AE Techron have been up to? I should call.

Hi Barry,

Ashly still makes in the USA quite a few amps "Hand-built in Webster, NY": SRA series, NE series, NX series, TRA series, etc., in addition to some mixers and other stuff. Those made in the US are identified as such in each product data sheet. EQs and X-overs appear to come from China. Ashly is a division of Jam industries, a Canadian Company, remember your neighbours on the NORTH side Border? Jam operates in Canada under the Erickson name and is the largest audio distributor in Canada with many famous brands from everywhere. Divisions are called Erickson Audio, Erickson consumer, Erickson Pro, Erickson Music, etc.

Therefore, you still have the opportunity to purchase a good old American made Amp with a 5-year warranty, while the Company lasts, which is subject to people encouraging them by purchasing their products... Regards,

Richard

P.S. I'm considering some SRA series amps, but again I'm not in the same league as you are with DSP Touring grade amps.

FYI -

Many years ago QSC was under contract to build amplifiers for JBL. Harman made an offer to buy QSC, but Pat Quilter and Barry Andrews declined the offer. It was shortly after that Harman bought Crown. It broke my heart to learn Crown sold it's soul to the devil, now look where they're at. Kicked to the curb like so much dead weight.

HI Richard;

I have perused the sites and there is some nice stuff out there. Few have the power density of Crown, Linea or Lab and fewer still can couple that with DSP at the level of the BBS onboard the I-Tech HD's or Linea's IIR, LIR and FIR loaded amps.

Linea's 20kW 2u amp is something to behold but this is about Crown.

I lost interest in Lab when they were bought by Music Group.

I checked on my order and it has been pushed back again. Very disheartening. It sounds like there is some small building in Texas to serve as a distribution point from Mexico. Yipee.


HI HF!

At least the brothers still have Crown Broadcast, where it all started.

At least Harman spun off Techron (Crown Industrial) and TEF and didn't just kill them off.

I am a manufacturer and my be overly sensitive to this, in short it really pisses me off.

Barry.

[allen mueller]

Crappy news but sadly I can't say I'm surprised based on Harman's past history. I've always been a big Crown fan.

Hi Barry,

Years ago I lost interest too in Music Group even though they have some nice names such as Midas, Klark Teknik and Lab Gruppen. Uli Behringer has had the idea, from the beginning, of making just about everything he sells in Asia for lower cost. No thanks for me. Though I don't live in the US it breaks my heart too to see these things happen repeadly, even in Canada going to the US (not much anymore) but more often than not going to Mexico or China... with no word said or effort done by the Prime Minister! What a shame!

I don't think one can be overly sensitive about this. The manufacturing base, and the good jobs that come with it, in the US and Canada are being given/traded away for little in return... I'm as pissed off as you can be about it.

BTW The vast majority of my audio gear is older and was made in the USA, like: E-V mics, Mackie consoles (from the time Gregg Mackie owned the Company, and still working fine!), QSC/BGW amps, Rane EQ/crossovers, Audio Logic EQ (DOD's great high-end line but for a short period), some Furman Sound, etc. Plus I drive and enjoy (even if not popular in "auto circles") a small Buick Verano also made in the USA. Finally, every year we take our vacations on US beaches... No wonder I'm considering some Ashly amps to replace an aging BGW, plus an Audio Control Real Time Analyzer. Regards,

Richard

Looks like you're out of luck all around then: "The Verano will be phased out from the US market after 2017 model year. The second generation Verano will be sold exclusively in China,[14] (https://en.wikipedia.org/wiki/Buick_Verano#cite_note-14) leaving Buick once again without an entry-level sedan in the US market."

Hi BMWCCA,

Sadly, I had a good laugh about that one from you. Thanks for the humor well placed in the circumstances... Looks like Harman will make Crown "obsolete" some day... Even though I don't own any Crown (it was way too expensive in Canada previously), I've always admired the Company for many of its products, such as PSA2 and Macro-Tech amps for example (not the cheap Chinese stuff). I still have on walls in my home studio, along with many more from other manufacturers, old Crown amp adds, one of them says in bold letters, above amp picture, "Imagine Getting Slammed In The Chest With A Sledgehammer." I guess these were the good old days now...



Looks like you're out of luck all around then:

As for the car, I knew some time ago it would not be replaced after 2017. Since I don't do a lot of mileage and tend to keep my things for a long time, it doesn't bother me any time soon. In case of total loss or stolen I'd buy a good used one again!

As for sound Equipment, I'd rather purchase quality and reliability and have it going for a very long time, like the gear I have now, than a lot of cheap disposable stuff we see today. I once purchased a Yamaha P series amp and after not so long it ended up on the side of the street next to the garbage can (seriously)...That's how build quality was, not worth the money to have it fixed. Sadly, It is getting more and more difficult to find good quality stuff made in North America (excluding Mexico) at a reasonable price... Regards,

Richard

Hi All;

As many of you may know, AE Techron is the industrial division amplifier company in Elkhart Lake only several miles from Crown. They shared many models together over the years from the D75 to the MacroTech line.

I dismayed as the list of Crown amps that Crown would service in the mother ship dwindled rapidly over the last couple of years literally down to only current models.

I have had near zero success with the four amps I have in the two current “Crown Authorized Repair” repair centers here in Las Vegas. Two of them actually worked properly when I picked them them up. Three of them went back multiple times and two are still, months later still there. One actually dropped burning embers out the bottom of it during it’s second hour of post repair operation. Pretty cool.

Two weeks ago I called Lisa at AE Techron as I now have one of their 30 year old amps that shut it’s self off and needs repair. Here is what I learned:

AE Techron is now not only a Crown Authorized service center but a warranty repair center as well. They picked up five of the best techs from the Crown facility and have opened a fourth division dedicated to the repair of Crown audio products.

Having utilized both facilities in the past (I have more than 20 AE Techron amps) I can say with absolute confidence that all our great experiences with the Crown mothership will be equalled or better with AE Techron.

The list of repairable models is very long so I have half a dozen amps going back this week that Crown said no to.

Also I think I know what my next two mono amps will be and where they will come from, a non shareholder owned company with old fashioned values that actually wants to stay in business. Discrete component, 900Watts from DC to 300kHz, current product made in Elkhart Lake Indiana USA. Hell yeah!

Barry.

[SteveJewels]

That is good to know. Techron amps are used in my work, I see them all the time.

One of the tests we do to electronics for commercial aircraft is to generate audio frequency interference and either couple it through a transformer onto the power input line. Aldo we create either an electrical or magnetic field and expose the avionics to that.

Hi Lost...,

Since you requested it in post # 14, and considering the fact I see No copyright indication anywhere on the document, here's a picture of the Crown ad. No sledgehammer anywhere in the pic though! Bottom left, talks about "...bone-rattling bass..."

Because its been pinned for 20-25 years or so, maybe more, on a wall in my audio room, along with many others from different equipment makers, it has changed color a bit over the years...

Funnily, bottom right of the page, Omnimedia Corp. Crown's Canadian distributor at that time was previously the distributor of BGW amps in Canada for many years, as well as Gauss and others. Regards,

Richard

Great News Barry about AE Techron servicing Crown.

Thanks for sharing that!

:)

[SteveJewels]

I use Crown amps to power my turntable. 🙂🙂🙂🙂🙂

[LostInTennessee]

Thanks RMC for posting the add. I own 2 PS-400, 5 D150A Series II, 3 D150A, 3 IC-150A, 1 SL-2, 1 SL-1 (AMCRON version), DC300A, and 2 XLS 1000. Big Crown fan here....

What do you use for a signal generator?

Barry.

[SteveJewels]

What do you use for a signal generator?

Barry.


For version one, which is the version that was working when I last had it setup, I used a Hewlett Packard/Agilent 33120a. It is an arbitrary waveform generator.

It has Option 1, the high stability time base which is frequency stable to 1 part per million per month.

Version two, which I will set up when I get the gear to Rockford, uses two of the Arb Gens linked together. They have the ability to run one as the Master and the other as the Slave so that I can remove the phase shift capacitor from the turntable motor and power the two sets of poles separately. The slave Arb Gen can be adjusted to be phase delayed relative to the Master.

I haven't figured out how I will determine the optimum phase shift to use nor how to monitor it. I do know that more phase shift (as induced by the capacitor) is needed to start the motor than is needed to keep it running. I am hoping that I will be able to determine by listening the optimum phase shift needed to minimize lobing. Here is a link to a paper on ESA, Electrical Signal Analysis, of electric motors. https://oaktrust.library.tamu.edu/bitstream/handle/1969.1/156349/Li%2C%20Yong.pdf?sequence=1&isAllowed=y

By using Arb Gens, I can also program the shape of the 'sine' wave. It is possible that having a more rounded shape to the top of the wave may reduce the lobing effect.

Using Arb Gens will also eliminate the inherent V vs I phase shift that occurs when a sine wave voltage passes through a capacitor. If V and I are in phase before the capacitor, I will lead V after the capacitor, adversely affecting the Power Factor. A Power Factor of 1 is when V and I are in phase. Anything less than 1 is undesirable. ELI the ICE man is everywhere. LOL

I grabbed a pic of a Techron 7700 we are presently using in the lab to generate electric and magnetic interference to test avionics for a 777X. I will post it when I get a chance. 2,585 watts into a 2 Ohm load. Several can be ganged together if you need more power.

….I haven't figured out how I will determine the optimum phase shift to use nor how to monitor it. I do know that more phase shift (as induced by the capacitor) is needed to start the motor than is needed to keep it running...
Thinking out loud, and simplifying as I go, if the motor is elastomer mounted, make contact with anything perpendicular to the shaft on its case with the stylus of an old turn table and o scope the magnitude of the lobing forces in the shell, adjust phase to minimum? See, I really am a hack.

I love those things! I have four 7782's, perfect for audio.

interesting link on motors, still chewing through it.

[SteveJewels]

It has been a while since I have torn it apart but IIRC the motor is hard mounted. Here is a pic;

I was thinking of trying a 3 axis accelerometer, using just X and Y and adjust as you suggested, for minimum vibration.
