Hey, got a problem that I need some direction on I am swaying towards a fader being bad . Ok here's the problem .

I get to a show last weekend and got everything plugged in, testing the mic in channel 1 and nothing . Unplugged it and tried different cables and different channels in my snake thinking it was that. So I checked the pfl to see if I was getting any signal . There was signal coming through, so later I checked the monitor to see if it was coming through the monitor aux and it was so I am wondering if it is the fader or something else before I take it to the shop. I did hook it up at home and it was doing the same thing. Any suggestions?

Dear Jimmy,
Did you check that the "Main" button for that channel is engaged? You can find it at the bottom of the channel strip by the fader. If this is not engaged on a given channel, that channel will not reach your main mix. If you need further assistance, please contact our CARE department. You can reach them at 702-800-8290 (US), +44 1562 732290 (UK), or at [email protected]. Feel free to also reach out to me here anytime.

Is parts hard to get for this board?
 
Re: Behringer sx2442fx fader might be bad.

If out of warranty just mark the channel bad and don't use it. I'm sure that's what most of us do with those. They are basically a throw-away mixer, not easy (or cost effective) to service. I have a 2222 with channel #1 bad myself.

Hello

Problem with budget boards is, that while they are easy to build, some of them are next to impossible to service. There might be a pc-board, that has 8 channels on it - with soldered jumper wires to next board. To open that you should open bottom plate, pull out every knob of all 8 channels, open huge amount of nuts and screws, then see if you could turn the pc-board out without unsoldering jumper wires - naturally the whole chabang must be supported in upright position. Then you can start looking for actual problem...

It could be, that there is channel ON- or MUTE-switch simply in series in audio chain ( even modular Soundcraft Delta / Venue had a flimsy switch like that...) - those go bad now and then - there might be bad solder joint in audio chain. Or the fader could be gone. If fader is separate from board, it is easy to replace, but if it is on board - which is likely in this case - you are up shit creek again - sorry

Looking for something like that on double-sided pc-board with modern miniature surface-mounted parts is pain i.a. but it can be done. It is quite time-consuming, so there is no point paying for the labour, while it can take hours to find and fix it.

On the other hand - if you have SOME electronic skills and plenty of time, you might try it some day. Quality soldering tool with good solder removing tool are a must !!!

Generally, faders don't tend to suddenly go dead. Most likely it is the main assignment switch. Test if the subgroup switches are dead as well. Also check if you have aux sound on both pre- and post-fade.

Hey John,

I called music group this morning and they told me that it had to be a authorized service place before they could sell the parts. The only thing is that we don't have one around my area , is there any other route that I could go to get what I need?
 
Re: Behringer sx2442fx fader might be bad.

Hey Guy's , a little update on my Board, I took the time to check it out and the fader isn't bad so its got to be in either the chip or something, we also checked the resistors or the transistors one or the other , I cant think of which ones we did. which ever one we checked those aren't bad either.
 
Re: Behringer sx2442fx fader might be bad.

How did you confirm that the fader isn't bad?

Faders do go bad, as do solder connections and the like.

If PFL works there is good signal down in that general area, but it is getting lost.

Pretty simple circuitry. Look for something obvious, maybe tap around with a pencil eraser while listening.

We tested it with a meter.

Hello

John is giving good advice - we had once a Fender Pro Reverb, that was occasionally giving grief - one night I took it apart and started tapping it with plastic handle of screwdriver, while powered up - surely I found a resistor that was actually physically broken in two pieces, that were leaning against each other - meter reading was o.k. but tapping caused intermittent connection.

Hair dryer and cold spray are good, too in low voltage circuits.

In the workshop we used to call this "percussive maintenance" :D~:-D~:grin:

See, I thought "percussive maintenance" was beating on something to make it work. The technique JR has outlined is a perfectly valid, very useful troubleshooting technique for intermittant equipment. It is also much more delicate than what I've seen referred to as "percussive maintenance"...
