Soundcraft DC2000 help
Try this.... A fellow named Alex will probably take your phone call and
refer you to a DC-2000 specialist. http://www.creationaudiolabs.com There's a DC-2000 across the hall from me right now and I haven't even checked to see if there's a way to hook up an external monitor to the desk yet.... our display is getting dark after an hour or so. -- David Morgan (MAMS) http://www.m-a-m-s DOT com Morgan Audio Media Service Dallas, Texas (214) 662-9901 _______________________________________ http://www.artisan-recordingstudio.com "JP Gerard" wrote in message ... Hi boys, I desperately need a DC2000 touchscreen... anyone knows where I could find one? Errr, a working one of course ;O) Looks like Soundcraft are out of those... Cheers, JP |

The man he will refer you to is an ex Soundcraft employee, in on
the design of the 2000. I have to talk to him soon as well, I have some metering crosstalk as well as the dimming touchpad. They just refurbed our PS last summer, so it's not directly associated with the dimming screen. DM "JP Gerard" wrote in message ... Thanks David, I'll check it out. I'm curently going through the schemos, hooking up an external screen+keyboard seems the most logical way to go at this point. I haven't opened the desk yet, could just be a PS problem, but I'd like to have the option of plugging an external screen anyway.

"Predrag Trpkov" ... Is that console functional at all without the touchscreen? Predrag Yes. One might be stuck with some odd-ball metering options, but if there are no 'saved' parameters from the automation side, and no session 'recall' data is loaded from the floppy, then it works just like any straight forward mixing desk. Most of the assignment and routing options (which are indeed a little different on this desk) are handled by physical switches. I've run a number of non-automated sessions on the desk and the only reason I touched the screen was to select peak, avg, or VU meters... and to select which source that the meters were indicating. JP is waaay ahead of me.... I haven't even *opened* the manual yet !! -- David Morgan (MAMS) http://www.m-a-m-s DOT com Morgan Audio Media Service Dallas, Texas (214) 662-9901 _______________________________________ http://www.artisan-recordingstudio.com |

I have heard that a comon problem with the DC2000 screen is the backlight failing - this is relatively easy to fix. Apologies if this is definately not your problem.

A friend of mine has one and the psu section for the screen caught fire,
destroying the pcb. I tried to bodge a fix but he hasn't had the time to see if it works yet. Anyway, the power supply required for the screen is pretty complex - high voltages positive and negative. It is derived using an oscillator circuit and the whole thing to me looks like a horrible bodge job. Which is why I have no qualms about trying to fix it using another horrible bodge job. The manual contains the complete circuit, so it should be fairly straightforward to find out if the required voltages are there or not. A good place to start anyway. You can buy EL sheets to fix the backlight if this has gone. Gareth. "JP Gerard" wrote in message ... There appears to be some regulation and general PS rail treatment inside the console though, so even with a brand new PSU, some problems could still be power related. JP |

Read my other post in this thread - sounds like the screen PSU has done the same as my friends one
 "JP Gerard" wrote in message ... When we powered it up the day we were checking it out, the screen was just non functionning... I was told that it shut down in mid-session and a puff of smoke came out from the console somewhere around the screen... that's all I know - but I'll find out more soon enough.

p.s. I have scanned images of the schematics of this section if anyone
needs them. |

I'm fairly certain that I have everything that there is to have on the desk as pertains to manuals. Between Gareth and myself, I'm sure we can get you any missing pages if the guys in Nashville run slow on you. I've been thinking about having a little hot-shot recent recording school grad come over and bring up the automation and then teach me. g DM |

Now that motorized faders, its main advantage, are no longer a big deal, can it hold its own ground based on sound quality alone? I think the 2020 has incorporated whatever 2000 users complained about. g After just a little reading on the two desks, the 2020 is probably a little more user friendly than the 2000. A big drawback to these desks is that the channels are not individually modular, but are removable only in groups of 8. As to sound quality, I believe the answer to your question is yes. Based on what a lot of folks are buying for consoles these days, given the average resale price of this desk there's a lot of bang for the buck there - and most everything about it is very 'Soundcraft'.... nice musical EQ, good routing, beautiful faders, yadda, yadda.... Of course, the fact that everything on the desk other than the mic inputs is routed through ELCO connectors, is somewhat of a pain in the buttocks. -- David Morgan (MAMS) http://www.m-a-m-s DOT com Morgan Audio Media Service Dallas, Texas (214) 662-9901 _______________________________________ http://www.artisan-recordingstudio.com |

I haven't bothered the guys at Creation Audio Labs too much yet, since they didn't sell me the board directly. I may end up getting back to you about that screen problem once our 2000 is pressed into real service. It may not have too much life left once the desk starts seeing some real operating time. DM |

For some reason I asssumed that the voltages produced here were to drive the display in total, but after your above reply I now suspect this is purely the backlight supply. (I didn't have the screen to check where the wiring went to.) This part of the circuitry produces +75 volt and -30 volt rails internally, and the output could well be AC - I'm afraid I'm not much good at translating oscillator schematics. If all that is required is a high voltage AC, just like most EL backlights, then you should be able to use an off the shelf inverter as you suggest above. My friend has already replaced the backlight with EL sheet so either this is the supply or there is a separate inverter somewhere. I'd be more than happy to post somewhere or email the schematics to someone if thay could tell me what the output from this oscillator circuit actually should be. Thanks, Gareth. |

OK, managed to answer my own question.
This section IS the backlight power supply and the backlight IS an EL sheet, so this circuit will produce in the region of 10 volts AC or so. My friend has successfully replaced the backlights with standard EL sheets, and as a result Soundcraft now directs all such enquiries in the UK to him, though he is not really interested as this is not what he does for a living. Apparently, according to a guy at Soundcraft, this circuit is known to be a bit dodgy, and any of the (11) transistors showing any signs of heating should be replaced immediately. A better bet, in my opinion, would be to replace the lot with an inverter . Except I seem to remember there is not a lot of room inside. Cheers, Gareth. |
