Am I crazy? Are there no Left-Right output level trims to calibrate? The only adjustment I see is the balanced o/p symmetry. If there is a level discrepancy...
There are no trims. They were factory set and matched to less than 0.1 dB. If there is a level difference between the left and right channels you need to look...
I am seeing about a .25 dB difference in the following scenarios- -1k tone on any input module, panned to the middle. -Slate (any freq) "mix" assignment...
One of the line inputs on my console is about 7dB lower than the rest. I can fix it with the line trim, obviously, but the VU still reads at -7dB. Just...
... Sounds like your missing a polarity. Did you try patching a known, good +4dBu to the input? Check that both + and - are getting to the input, no broken...
With the pan in the middle with input to a channel there is +/-0.5dB difference between panning left to center or right to center. The slop in the detented...
Sounds like a wiring problem. Either one side of the balanced input is bad or not connected, i.e. shorted to ground, if you are running an unbalanced input. ...
Again I don't understand the real problem as the two mix SLATE bypasses the mix amplifiers, ACN. It goes directly to the DLO or diff output. Sounds like...
Best of Luck. I have not seen this and we designed the Board to eliminate problems like this when Calibrating Tape machines. Later Tom graefe@... ... ...
Hi everyone, Thought i'd let you all know i have some Forssell Inline channels for sale. Five to be exact. I've put one up on ebay with the option to buy the...
Can these be used along side the standard modules? How is the extra aux send implemented? Douglas Ferguson mobile: 512-293-7279 office/fax: 512-462-0408 skype:...
I e-mailed fred a while back about these modules. You can used the forssell modules with the standard modules but they do require Analogue faders though. they...
so for the truly MXP knowledgeable out there.... My tech and I spent the last day or two replacing a voltage regulator in the PSU and still having to deal with...
The voltage regulator is a 723 opamp not a transistor. The Darlington pass transistor usually blows do to poor ventilation and or a silpad under it, or a...
thanks Tom! That is immensely helpful. Now for a couple of more queries, perhaps they are easily answered, but .... Do you have any insight as to why plugging...
Matt, Perhaps a resistor standing up on channel 7's card touched the back of channel 8 then smoke. The switching of the mic line is a common problem USUALLY...
Hi -- After a power outage last week, the power supply for our MXP has lost its +18 and -18 rails, in addition to the 24v rail which had died previously. I've...
Hi -- After a power outage last week, the power supply for our MXP has lost its +18 and -18 rails, in addition to the 24v rail which had died previously. I've...
... Are you saying that it's lost ALL 3 rails this time? How about the 48V? If I'm not mistaken, there is a fuse on the input side of the transformer that...
The 48v seems to be fine, but the 24v and both 18s are down. We've tried unplugging it from the board, but it exhibits the same symptoms. The fuses seem to be...
Matt, Everything Jeff said is correct. About heat sink compound, it is mandatory! You have a continuous 10 Amps through one Darlington transistor. It will...
Thanks for the help -- it's greatly appreciated. The fuse holders look OK, but I'll ohm them out tomorrow. (By the way, the 48v supply has never failed, so...
... That's good, you can pretty much assume that everything on the primary side of the transformer is ok. ... First, you should get all the power supply rails...
Jeff, That is exactly the way to go! Except this sounds like a short in the console and not on a module. The modules all have fuseable resistors on them....
Hi Tom & Jeff, You guys really seem to know your stuff. I'd like to ask your advice. I've had my MXP 3000 for about 4 years now. I NEVER turn it off. Unless...

Steve, The inrush current on a cold bulb blows it. It was already past its prime. I would turn the console OFF on the days when you don't use it. All...
When my console was at the studio that originally owned it, it was on 24/7 for almost 10 years. Our major problems over that time were a couple of failures of...
Thanks Tom and Jeff for the quick response. I guess I'll be turning it off on when there's nothing going on. It makes total sense. You're right. What's a...
