My digitech rp 250 guitar processor seems to be frozen. everything is all lit up and its all zeros in the display screen.

Here is a link you will need to the latest firmware update: Make sure you follow all directions carefully. Look in your owners manual at how to reset the pedal. If all this fails contact support at their website. Also you didn't mention if you were using a Mac or a P.C. so I gave you the P.C. link. The Mac link can also be found there. Hope this helps.

I need an IR led of 4.3um for my project capnograph thats basically a medical application, so please if you can tell us the manufacturers of that product.

The best way to fine your answer for your capnograph is to call your local hospital and tall to a hospital engineer. They always work on medical equipment and can give you who the manufacture's name and phone numbers. And you may never know, maybe they just might have extra parts or the same equiptment just lieing around taking up space. Papabear

Dbx Driverack PA LCD problem

I just read in another forum that the LCD display appearing black (but backlit) could be due to the ribbon connectors being loose behind the screen.
You would have to open the unit to check...
However, this would most likely void your warranty if your unit is still under one.

Hope this works...

If you have set the EQ curve to the typical "disco smile" ( where the curve looks like a smiling mouth) that everyone who is inexperienced seems to do, then you have turned down the midrange area. Human vocals appear between 200hz to about 5kHz. If the vocals are clear when the unit is in bypass mode, then you are not operating the eq properly. If they are not clear when the EQ is bypassed, you have another problem. The best way to run an EQ is to leave most of it flat across the entire range, at zero gain and CUT only the stuff that is annoying, or caused by your room or speaker limitations. Try this first, before assuming you have a hardware fault.
