I usually wouldn't slam a manufacturer. But these people want nothing to do with there customers. I volunteered to try to help Gsteg fix an amplifier he sent me. So I call up and request a schematic. They say "sorry those are under copyright protection." LOL if an egineer wanted to copy a design it wouldn't be difficult. I don't know any other manufacturer that does this. Even Sony will sell you a schematic to all of there equipment. Just Yesterday I asked Soundstream for two schematics to the amplifiers I own. They sent them to me free of charge the very next day.

Heres the bad part DEI is going to decide for you when your product is outdated not you. All they have to do is stop supporting the product then you are forced to buy a new one. IMO if you really like your equipment and want to invest large money into it I would stear clear of them.

 

DEI is not crap


my 1100D directed amp is the **** and im looking for another one, so what if their customer service sucks, big deal

im a directed fan for life

 

Until the day you do something to your amp and they say sorry we no longer support that item. Your $600.00 or whatever it cost is down the tube.

If I was going to "invest" in audio equipment I would look into finding someone that looked out for the customers best interests.

If your looking for throw away audio then great. But I can think of a few manufacturers that they now own that I wouldn't consider throw away audio.

 

ok well its different from me i don't get warranties nor do i keep equipment long or reallly give a **** about it its material things


you should have said DEI customer service is crap not DEI itself

i just hate to see someone call a product crap because of the company, no offense

sigh....

 

i've own two DEI 1100d. the old one (i loved that amp) and the new one (i think is worse compared to the old one).


i've only talked to John Durbin of DEI for help and he was helpful.

But talking to others on other forums, DEI service=teh sucky.

Guess i got another paperweight on my table now.


time to find another one of those older DEI.

 

Sounds like bad install.

People ask us for schematics all the time, and we don't give them out either, so it's not just them.

There is more than one way for an amplifier to go bad. Electronic parts wear out over time exspecially semiconductor devices and electrolytic capacitors.

Gsteg,
I'll get it to work it will just take more time. They scratched off the markings on the Pulse Width Modultation controllers so I can't even look up a data sheet for the part.

If they had some leading edge technology I could understand the secrecy. There is nothing that spectacular or leading edge about amplifier design. The same approach has been used for years. There are some main differences class A, classB, class AB, classD you pick one and go with it. If you flipped through all the major designers I think you would find some extreme similarities. Class D is the simplest.

I have access to just about every other schematic there is. This is not common practice. Like I said I requested one from Sounstream and recieved it 30min later free. Along with help from a very helpful representative.

 

heh, heh... yup, Bassisliffe is very brand loyal...
i'll say that Directed makes decent amps, but Bassisliffe, you will never know what else is out there if you think you have the best... there is much better equipment. like a Sony CDX C90...
nsxextreme, e mail me a pic of the board, top and bottom, and a model number in case it's not printed on it. if any of the FET's or chips are not visable in the pic, im going to need to know what they are. im on 3 Meg cable, so pics can be as high resolution as you can get.
also tell me the problem with the amp. i'll draw up the appropriate schematic, or, we can just troubleshoot it right here.

Hi Dave,

Thanks for the offer of help but I think I will be fine. I am an EE I just wasn't intending on backwards engineering a design.

Regards

 

take as long as u need nsx.

i have a whole life ahead of me anyways. lol.

not too concerned with it. I'll use a different amp for now, even if it meant dragging out the Road Gear.


but really, i'm patient and i trust you. lol.

heck, i even forgot about the amp until you made this thread. LOL!

i never said directed was the best, but i know its better than any sony amp ever made

 

uhhh... you better check out Sony's M1, and M3 amps from the old XES systems. having worked on quite a few Directed amps, i can tell you that Directed does not make an amp of this quality. ( including the Orion HCCA 2100 that i have sitting in a corner of the shop )
you keep slamming Sony... what you have no idea about, is that they used to be into audiophile grade car audio. what they made back then, is still state of the art now, and better than 95% of the mass produced crap made now.
sure, the Xplod stuff is not so good... they have the knowlege and technology, but they also have a marketing dept... lets face it, it's more profitable to sell 100 cheap units, than it is to sell 10 high end units. so it goes... oh well.
nsxxtreme; i too am an EE/ME. i was just offering because depending on the model, and revision of the board, i may have already reverse engineered it, and may have a folder for it with schematic. i have done at least 1500 amps and head units this year, and have been keeping extensive records for the last 6 months. ( i have no idea why i diddnt for the past 5 or so years... )

Sony stuff is great exspecially when ES actually meant something. Speaking of I can get any schematic for any Sony product in a matter of minutes LOL. A lot of the low end sony stuff does suck.

Dave Orion is now owned by DEI if you have schematics you better hold onto them.

If I run into a problem I'll let you know. My biggest problem is finding time to work on it. I have waaaaay to much stuff going on.

 

yeah, DEI customer service is pretty crappy

i know all about good sony products, i had an amp that was a classic 400 x 4 it was blue don't remember the model, my friend has a sony double din radio with features from here to mars and is the most solid unit ive ever heard


i just think 'explod' when someone on here mention sony, just because i figure no one uses the old good stuff again, my bad

 

nsxxtreme;
yeah... just like Xtant got bought by MTX, Soundstream got bought by... i forgot, and Orion got bought by Directed... thats why i mentioned my HCCA 2100. thats the 100 x 2 SPL competition amp of the old days. almost 3 feet long, and more N Channel FET's than i can count. 1/2 ohm stable. 2 x 100 = about 1600 right ? i have no idea what im going to do with it, ( too dirty for SQ ) but it's been decorating the corner of the shop for a few years now. i'd make an SPL car, but i cant stand the sound quality of an SPL system. ( im too old maybe ? )
bassisliffe;
yup, i have no idea what amp you had... but if it had blue heat sinks, that was the first generation of amps that used the IRF 540/IRF 9540 FET's. it also happens to be pretty close to the design of the first generation Xplod amps. ( the new amps still use the same FET's ) however, the blue heatsinks ran a _lot_ cooler than the new amps with no fins at all.
however, it is pretty sad about the Xplod stuff. Sony has proven that they can make some of the best out there, but i think marketing is now a much stronger department than R&D... oh well, there is other good stuff out there.
