Digipro 1000 RCF/ DB Technologies
Hi.
Them assholes at Db Tech refuse to send me schematics of their Digipro 1000 Bi-amp, smps unit. I stay in South Africa, and have about 8 of these units faulty that come from their various products such as S09.S20 Subs.....
They want me to courier these units which way about 5kg, back to Italy for repair. WTF? The importer here in SA says not even he can get the schematics from them, and we have tried believe me!!
What to do know They all have the same problem. Thing is its a bit difficult to pin point the exact fault etc due to the dark colored double sided Pcb. Also they have PFC circuit on smps and a load of SMD components.
Anyone willing to help?????

DigiPro 1000 - Copied from the board, errors are possible. Need to register for free. Enjoy.

I feel for you as far as not releasing schematics.
And that dark colored PCB is tough to trace out (ala Bugera).
It may pay you to return all of the equipment, seeing that you have so many failed units.
(You can spread out the freight charge/ unit)
They just may have a factory "fix" for the failures.

I can't seem to register. Even if I translate.

I do not fix SMPS on a daily basis but in all cases when I needed to fix such a power supply I managed to do it just by checking for shorted output diodes, shorted power MOSFETs, open/burned resistors and failed controllers. Did you check semiconductors for shorts? Any burnt resistors, ICs? Are you able to identify controllers? Any signs of fire?

They probably got tired of supporting people. Many audio repair techs don't have a clue how the switchmode stuff works and would just blow it up even further and end up having to send it back to DB anyway.

If you are serious about trying to fix the things, do as Markus says, start by checking all power semiconductors. You don't need a schematic for that. Sometimes a MOSFET or diode will just blow up and all you need to do is replace it.

If that doesn't do it and you need to start troubleshooting, you'll need an isolation transformer in addition to the usual audio tech gear. At least one third of the circuitry is unisolated from the mains. An understanding of how Class-D and SMPS work would also be important.

1. I have aforementioned schematic.
Due to 6MB volume it's impossible to upload it here.
One who wants to obtain this shematic - send e-mail address.

2. The power amp schematic is correct.
SMPS schematics may be correct as well.

3. Registration process at referenced site has some bug.

J M Fahey 7/25/2012 11:06 PM
Dear diyididi , I can't believe the situation you are in.
Here in Argentina (country comparable to SA) official products importers or representatives are forced *by law* to offer local servicing, including stocking parts, and if they don't , face heavy penalties.
Sending stuff back out to original Country is *not* an option.
I'm amazed that the SA distributor is not forced to do something equivalent.
Of course, if you brought stuff personally, or bought it from a touring band, or got it used, it's on you.
The only way out for somebody who sold you new but unrepairable stuff is to offer you twice your expenses, starting with the price you paid for it and ending with any other expense (including Legal) you incured into.
Ask a Lawyer, (or a Consumer Help organization), I think some equivalent Consumer Law must protect you.

thank you again

diydidi 8/27/2012 10:32 AM
Just some feedback for you all Since having started this thread, I have successfully repaired many of these units. But I've decided to send these repairs away, as they can be time consuming to repair. So be warned.. The parts are a bitch to get and those smd's are small. A tip for you all: check those through holes and smd capacitors!!!
 
paleeman 8/27/2012 1:39 PM
Thank you, Diydidi! You helped us all. A nice slap in the face for the "secret society of DIGIPRO" :-). My tip:check the 4R7/5W resistors on the amp board, resolder and reglue if necesseary.
Greetings and thanks to doctor and sentim!

These schematics are the result of the reverse engineering.
The author is unknown to me, but definitely he is the professional.

Clearly schematics may contain some inaccuracies.
Nominal values of some elements especially SMD capacitors are not marked.

But this is more than just concept and really can help.

Good luck to whom it may concern.

It is not that difficult of a thing to do.
If the file is too large, use Cute PDF Writer to knock it down.

scheme stadium entrance rcf art 712 (digipro 1000s), good morning to you all and thank you for accepting me among you. as the title suggests I am looking for service manual schematic diagram
rcf art 712 (digipro 1000s), I have already consulted your valuable schemari Publicato you and thanks to you I managed to fix the final stage of this case, but it is not 'over yet, I have a problem on the form where you connect the tallow where audio and adjusts the volume. someone can 'help me? I thank you in advance and sorry for the trouble the mind. a warm greeting from john
 
J M Fahey 1/13/2014 10:35 AM
Caro Giovanni , there's some problem with the translator you used, your question is not clear.
Just for this time, repost it (in English) and also in Italian.
You must be very careful with Translators and write in perfect "literary" language or they miss.
Also perfect punctuation, spaces after semi colons, etc.
And they don't understand dialects, even technical ones.
 
alieno68 1/14/2014 12:11 AM
Hello to all the community, I apologize if my previous post was not clear, but I use google translator.
I'll be synthetic. They have a RCF ART 712-A.
I am looking for service manual, schematic diagram for stage inputs signals (I'll explain: where are inserted the audio input jacks, BALANCED, INPUT-LINK, where ilregolatore volume and the button to switch to FLAT - BOOST). I hope I was clear and concise.
I apologize again for the trouble with all of you, I wish you a good day. John

You are still being careless.
Google will understand and translate "il regolatore" , but not "ilregolatore"
That said, what JPB posted and doctor originally provided is all the data that is available around here.
Hope it's enough, and if not, ask it straight from RCF
Good luck.

By the way, JPB underestimated the interest as "300" askers, fact is that his later post already has 500 downloads and growing.

Hello All

i'v had a problem in one of my digipro 1000psu and i guess i found the problem (zenner D8) and now i have all right voltage at the connector between psu and amp. (i have open the new speaker, mesure the voltage in one psu module that was ok with and without the amp connected to the psu)

When i turn on the main switch the speaker lights the "On" led, the "status" and "clip" led and then turns off the status and clip and stay only the power led ON, but when i insert signal in the channel it does not get any sound. i can hear a light zzzz on the horn

To do the voltage mesure i turned on the digipro without connect the speaker(12' inch and horn cables) connector in the amp module.is there any protection for this case that could mute the outs?

now i have 2 cabs with the same sintoms, that starts ok, have the power led on, but dont gives me any sound when i insert a signal at the input connection.

any suggestions??

thanks
 
chickenwatt 2/11/2015 2:55 PM
Hi, I'm servicing a rcf 4 pro 8003 which use the module Digipro 1000S, it workss but with 2 defects:

1- when I turn on it does not turn on in less than 5 seconds as it should, the power led start to blink each second with half led intensity for let say 20 seconds and then turn on

2- When playind loud bumping music it clips early maybe and the woofer sounds like the voice coil is hitting the magnet, like an extra excursion happened


Thanks in advance
