I have a level issue...I'm monitoring through a Mackie 1604 --2 channel stereo panned hard right n left. I seem to be getting more level out of the left side due 2 the meter running hotter...I've check all gain structure from my Mac running DP to my individual trim on the MAckie & master faders...all equal. If I even out the panning to straight up, all levels are even? Why when I go hard left n right for stereo spread do I lose level from my right side? Is this not the way to do it? thanks

Your 1604 might have ribbon cable & connector problems. Also, the Mackie pans are supposed to correct hard pan levels by +6db so there isn't any level loss (which there typically is on most consoles, engineer corrects at the fader). Could be the gain stage associated with the pan feature for your right channel is faulty. Check the Mackie users forum, they're a helpful bunch for all things Mackie.

just a question, when you solo the track and put the solo led readout to PFL, does it still have the same problem, if so its probrally from DP. So test it by sending out a mono signal from DP and solo the board in PFL mode, try different line inputs too. Thats going to show you the level hitting the board before any gain adjustments. Also are you using the steoe tracks rather than the mono ins that you have to go through the trim stage. And last but not least, are you leaving the master at unity and adjusting the faders level on the board, if so do the opposite, the master section has the most noise in the board, also you can go through the Aux returns 2 to moniter your signal instead of using the line ins on a strip, this gives you the least amount of gain staging in the whole board, also it bypasses the panning, trim, Eq, and fader section of the board, it sounds better. The signal flow off the Aux return is aux return trim, to the master fader, and once again leaving the aux return on unity and using the master fader for level adjustments, also by the way the aux return section on that board is the quitest section.

:) Just for the heck of it. Generate a tone on one channel only of your source. Apply it to any input. Set the fader in it's normal position (unity), pan center and adjust the trim for a reading of 0 on the output meters, making sure the output faders are at unity, punch up outputs to stereo. Pan left note the reading, pan right for the same. If there is a difference, swap the output connections, and try again. Sometimes the normalizing in the jacks can get dirty too.

There can also be some bleed from somewhere else in the board, from a send, or return. If this still does not confirm readings, then there is something going on internally, strap connections as mentioned, or an alignment. Resisters do change values over time, so an alignment may be needed. Trouble is, is it in the meter circuit? The summing amps? Or main output gain controls?

Good Luck, and I hope it is something simple.
