This just in -- we pulled all the modules and tested resistance between the 18v terminals and ground (as well as the 24v terminal and 48v). In each case, the...
Oops, I lied. Here are the actual resistance readings I just got (chassis ground, no PSU connected, all modules pulled) +18v = rose to 400 ohms -18v = rose to...
Matt, The ohm meter rising is normal. You are charging the caps on the DCC board. Don't worry about the paint flaking. It is conductive paint anyhow over...
Now this does not make sense unless the Positive and negative leads on the ohm meter were reversed? Tom ... Oops, I lied. Here are the actual resistance...
That board is quite simple; it's not a regulator at all, but basically a distribution point, with some capacitors for additional power supply filtering. The...
Jeff, I don't remember them being there? I can only imagine Karl put them there to discharge the caps at shut down of the console? I will pull out my manual...
The 18v legs are working again, but blow a fuse when I plug it into the console. I haven't fully investigated the 24v leg yet. Thanks, Matt ... basically a ......
Matt, You are turning the supply off before plugging it in? Are you sure the correct cinch plug is in the correct female plug on the back of the supply? One is...
http://www.mpja.com/prodinfo.asp?number=15785+FU You will need some of these Tom ... The 18v legs are working again, but blow a fuse when I plug it into the...
Tom & Jeff -- Thanks for your patience with this. I just re-checked the resistance making sure the leads were properly oriented, and got the same results. I...
Matt, Real dumb question. Check the L brackets that hold up the heat sinks in the power supply. Make sure one is not cracked or broken shorting the heat sink...
... Figure out the problem with the 24v supply before we go any further. Don't know what wrong there, but maybe it's related to your other problems? And lay in...
I guess I have a little too much time on my hands so I'm back to messing with the automation again. After lots of testing, prodding, and re-testing (and great...
I have an extra automation psu that I don't need. Douglas Ferguson mobile: 512-293-7279 office/fax: 512-462-0408 skype: stillrecording aim: DaAmericanRuse ...
Dave, I have a complete Automation upgrade kit. It was meant to upgade a non automated console to automated. It is all the boards and the display boards etc. I...
Here's a wacky question -- has anyone tried using the fader automation info from an MXP to control the faders in Pro-Tools (or other DAW)? Our MXP 3036 came...
I've given this a lot of thought actually. It would be really cool. I'm using Nuendo though. Nuendo has a really nice control api, but it is midi based.. So...
... I'd be REALLY surprised if anyone's been able to do that. It might be possible, but it'd take a serious hacker some serious time, for little end value. ...
Need information on fader calibration for AFB faders on MXP3036......also is there a pan pot calibration? some are off and not all faders are the same...
... Look in the files section of the Sony-mxp-3k group on Yahoo. There are calibration documents there (Thanks to guitarrone2001). I don't believe there's an...
Hey guys, I don't need schematics after all! While working on the console yesterday I found the binder with schematics etc. Apparently whoever was unpacking...
That is fantastic news! Not cool about the previous owner. Soon you will enjoy a great console. BTW the lamps are 28V Bayonet 35 MA lamps. Have fun Tom ...
... Far from boring the whole list, this is exactly what the list is for. Other members (present AND future, via the archives) might find useful information...
Tom, I replaced the P8251A (I hope that is the driver chip)chip on the CMB board, and the problem is still there. I even tried a second chip, same result. Any...
That is not the driver chip. IC18 is the output and IC 1 is the input buffer. For the RS232 which is the commands. The RS422 is the Data IC 25 and 26 but that...
Tom, I replaced, on the CMB and IRR boards LM2490, 1488, 1489 on the CMB board LS32, LS31 and the problem is the same, all the automation lights are lit up...
Dave, That problem does not sound like a communication problem but either the HPB or Fader Buss Processor board FBP. I did not realize the faders are locked...
Tom, when I turn the auto power on the led's do the top to bottom thing then the mute led stays lit, the readout says L and the on off switch stays lit and...
