Question about DBX DriveRack 480 Processing Unit Home Equalizer

1 Answer

I have a dbx driverack 480 that was professionally installed 3 years ago at our church, we have had to return it to dbx once for repair (just stopped turning on...) and it came back working like a champ. now a year or so later the outputs have begun cutting in and out and there is an audible "clicking" sound from the unit itself, as if something is arcing inside. all of the leds on the front appear to be working normally and there are no clip lights. i have no idea whats going on. help!

Test the XLR cables that go in and out of the dbx. It's kind of a long shot but I think it's the best place to start.

Driverack pa plus sends this message WAITING FOR FLASH DOWNLOAD V. 0.109. i tried hard and soft reset but nothing happens, is there a solution?


The unit has been put into the mode to reload the operating system. You need to connect it up and load it with fresh download of the system. You can probably download the firmware from the manufacturer's site in their support section. There may be no other way to restore it. Be careful as any corruption during a flash download can be fatal requiring return to the manufacturer for reloading. Find the firmware for your unit here:

Good day..The common problem in a closed pa system setup is feedback.It limits the capacity of unit to give a higher intensity of volume..With this I just want to ask if DBX Driverack pa+ will work well...


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.

DBX PA+ no settings for Yorkville EF500P and LS801P


yeah that is because Harmon makes JBL speakers and Crown amps..for Yorkville Speakers use the VTC DLMS4080 Speaker processor, it blows the Drive PA away...

No access to driverack 480 with belkin adapter


Hi there,

The Driverack Series all use a Null Modem cable for the connection to the Serial Port. A standard serial cable or female to female lead will not work, as the wiring has to be of the Null Modem type. A suitable lead should be available from your local PC supplier, failing that DBX can supply you with one also.

Hope that helps.

DBX DriveRack PA power failure


repair the transformers,,,using a digital voltmeter when both transfrormer are good the measure like 56 ohms, if one is good and the other is bad is gonna measure like 120 ohms , if both are damage it will measure nothing, all this with the switch in its on stage.

If you dont find anyone that can repair the transformers buy them.
