20 Most Recent DBX Driverack-Pa Eq/Speaker Control System System Questions & Answers

Blu wait disply

I can not tell for sure without seeing the unit; however, this often happens with stereo receivers when the contacts on the protection relay start to go bad. You can try to polish the contacts with emery cloth or a fiber brush but it is best to replace the relay if you can find one that will fit.

Does the display light up? If so check ribbon cable connection. It is probably attached to display and will plug into connector on board. Maybe just unplug from connector then put back. Also look at capacitors in power supply area to see if any are buldged at top. If so replace with same type capacitor.

Apparently you can assign stuff like that. Get the manual.

does this help?

The DBX driveracks work well with about any PA. The only PAs you might encounter a problem with would be one of the newer line array and digital processing PAs. Let your audio person get creative, the presets for multiple PAs are just a guide. If your sound person is confident and is qualified, let him/her experiment and/or rehearse - you'll be amazed at what that system is capable of.

Try reversing the polarity (orientation) of one AC power plug at a time.

yes a thin one about 1/2 inch dis stores the settings in the memory

set it up as mono=common leads together and l,r,leads together,it will see left and right are in use and should load up

By far the best way to do this is to have an RTA microphone. Set speakers and amp to custom, then run the wizard to pink the room. Then make sure to set up the gain structure (pg. 41 of the manual available online).
Although it's satisfying to see the name of your speakers and amp listed, if you follow the procedures above you'll end up with the same results -- a properly EQed room and an optimized gain structure.

You should be able to spin the dial all the way to the end of the list of speakers and there you should see custom.

As far as I know, you just turn the dial so that you can hear the pink noise at what you expect to the the normal listening level, hit "next page" then the system starts "listening" and adjusting automatically. If you set the RTA to high resolution it can take a while. At this point you shouldn't be trying to hit next page. Just wait for a while. Maybe 5 to 10 minutes if you're on high resolution, depending on your room and setup. Let it go through and EQ. After a while you'll get a black progress bar at the bottom of the screen, sort of like a file download progress meter. Let it finish. If it's taking too long check the manual for how to change the auto eq to low or mid resolution.

I hope this helps. From your post I can't tell exactly what's going on. Reply with more info if you like and I'll try to help again.

Check the speaker wires coming out of your amp. Chances are you have a problem with a speaker wire and this is just a coincidence. I say this because the same thing happened to me during a live show and I about had a heart attack. We lost the front of house for about 15 minutes while I tried to troubleshoot the Driverack, the board, and everything but the speakers and speaker wires. The cables were a recent purchase and were premium grade with light wear so I mistakenly ruled them out. It was intermittant so it took me a while to figure out. Now I understand that that's the weakest link in the chain and from now on I start there and work backward through the chain (that is, if all sound is cutting out).

Do you use banana plugs (two metal pegs sticking out of a plastic rectagle) coming out of the back of your amp? There are little screws inside the holes on the back of the banana plugs. Those can vibrate loose, especially if they're just factory tight. Get a little standard screwdriver and tighten them down. That will probably solve your problem.

Okay, wait a minute -- could be one more thing. You mention that the loud popping can be heard. Do you have any gates turned on? Most compressors have gates. Check your compressors to see if you have your gates turned up too high. A gate set too high would allow the loud pop to go through to the PA but would cut off everything low to mid-volume.

I guess you can see that I don't think it's a problem with the Driverack. I don't work for dbx or anything, I just think these other things are far more likely than a problem with the unit.

You have to press the STORE button. Also, this will only save to the preset you're on and has no effect on other presets. So if you're on preset 1 and you disable EQ then press STORE you've only turned it off for that preset. #2, 3, etc. will still be enabled.

After you press STORE will show you something like this:

STORE: ROCK VENUE
Replacing
U1 DJ Setup
PRESS STORE TO ADVANCE

Rotate the DATA whell to select the program to be replaced and press STORE. The existing program (the one that had EQ turned on) will be replaced with the new program (the EQ turned off). If, for example, you do this to preset 1, now every time you dial to 1 you'll have the same, no EQ setting.

You can adjust the LCD contrast by pressing the Utility button and turning the dial one way or the other. Pressing the Utility button toggles back and forth between LCD contrast and Compressor/Limiter Threshold Meters, so since you can't see anything in the window you may have to press Utility twice, though I think LCD contrast is the first option.
