To those who have the Behringer MX9000.....

I'm having an anomaly. My meter bridge LED meter registers at a lesser level than the bus and main mix meters do. When I turn the faders on each channel to zero db they seem to not match up! Shouldn’t they match up? I tried turning the input/mic trim up but that just increases everything including the buss led lights.

So I'll have the input faders set at zero and the meter bridge input LEDs will be at zero but the LEDs on the main buss will be registering at +4 to +7!! Is there a way to calibrate the LEDs? Am I going crazy?

Grego, do you have several tracks all playing at once when this hppens? The combined signals from multiple tracks will create a louder signal going to the busses or the mains. With each added sginal you are adding more gain that is making its way to the busses or mains. So in short, yes the busses and mains can register a higher level when all the signals are summed at the main buss.

Noize2u, no this is one input to one buss. I was testing out new mics I got, testing each channel seperatly.

EDIT**

I just tried it again with the LED on the mains lit up in conjunction with the Buss and input meters and the transient response of the meters for the mic inputs are dull and non existant(at -7db) when tapping the mic gently. However the Buss LED meters go all the way up to +7db and then the main LEDs going into +10db (the maximum that the LED ligts up to)
I've used a few mixing consoles and this is a first. It seems at each gain stage in the internal workings of the board are amplifying each LED to unrealistic levels! This will be a major pain in my *** when trying to get acceptable levels from the LEDs readouts. Maybe I should have went with Mackie. This is really ticking me off!

The channel meters are VU and the main bus is PPM would be my guess. Just giving you more information about your signal.

Gregor, I will email Walt as he owns a 9000. I am sure he may be able to shed some light on the sugject.

I agree with CS though that the meters balistics may be set to differant response types.

I know you have probably allready gone through this but I'll post it anyway.

Starting with every thing down you should have a button in the master section called PFL/SOLO with this button up to engage PFL (Pre Fader Listen0. This will allow you to only moniter the channel input level. I usually set my channel fader to 0dB to start with, but it doesnt matter if it is there or all the way off. Now turn your channel gain knob up untill you get a good solid green light on the channel strip itself. Only an occasional bounce into red if at all. Keeping an eye on the main meters. Set your level so that you again peak at the 0dB mark, with only an occasional shot over that mark. And you will get of coarse some signal over but that is OK as long as it is only a momentary peak. Keep an eye on both the channel meter and the main meter and see if this doesnt level them out some. I know they may not match perfectly but this should get them closer. But the main concern is your output buss or main meter. If you are monitering playback through channels on the board, this is when the channel meters will become more important, but again, musltiple channels will of coarse send more gain to the buss or mains.

Hope this helps a little.

Just got Noise's email and tried to duplicate the problem on my board. I can not create any such fee-nom-eee-non. There are only two scenerio's that I can think of off hand. Noise has already mentioned one, that being two or more channels playing into the mains at once. Obviously that is not the problem. The other scenerio that will create a larger than life reading at the mains is if you have the mic plugged into the 'A' side of the board, the direct out plugged to the input of a recorder/soundcard, the output of the recorder/soundcard plugged into the 'B' side of the board and you have the [assign to main mix] button pressed on the Mix B scction of the board. This will add the A and B sides of the same channel at the main out meters. The increase is usually about what you describe; somewhere between +4 and +7.

I'll keep thinkin on it, but for now that is all I can come up with.

Thanx Walt, I forgot about the A B thing. That sounds right though as again it is summing 2 signals and would increase the gain to the busses or main.

Thanx Walt, and good to see ya.

My pleasure Noise! Good to be seen and good to see you! New job, mega hours, nothing to report muscialy beyond a few rehersals since October of last year. I've got about 5 PO'ed bands out there. I did get all of the current contracts fulfilled, but all futures got put on insta-hold with the new job.

So goes the war!

The EQ settings influence "downstream", as would any "inserted" outboard devices...

I just wanted to say thanks for the replies! I will try what you said Walt. Thanks again!

I finally figured it out after almost pulling my hair out....... I had the left and right main mix buttons pressed! As soon as they were depressed (almost as much as I after trying to figure this out) every LED meter was exactly the same. So thanks to all for the help! I owe you one!

Gregor,

Just thought I would check in and see how you where doing. Glad to see you found the snafu. Gotta say I love the board. Maybe not the best board in existance, but it sure has produced some fine recordings.

Dear gentlemen

Newbie here (at the forum, at least)

I also have an MX9000 and experiencing the same situation as Gregor.

I have carefully read this thread and still cannot make my channel meter match the buss and/or the main meters.

I have even completely unplugged my multitracker in order to prevent unforseen signal summing.

If the channel is hard panned left or right, the difference becomes even more apparent!

Can anybody please detail master switch positions, channel switch positions, pot/fader positions and meter readouts at any given time?

Channel, buss and main faders are always kept at unity, but no matter what switches I try, meters will not match!

Please help! I'm about to torch this mixer!!!

Thanks!

Mike
