SYSTEM PROCESSOR TUNINGS
The following table includes the tunings for the dbx DriveRack 260. It is always a good idea to check for the
latest tunings on the JBL Pro web site at http://www.jblpro.com/pages/tunings/tunings_main.htm. If you have a
processor for which VRX tunings are not developed, the following table can serve as a starting point for setting
your processor.
Note to DriveRack PA users: The DriveRack PA does not include a POLARITY function. When using the
DriveRack PA for a tuning that requires the polarity parameter to be set to “INVERT” it will be necessary to
invert polarity at the amplifier output cable connection or by using a specially wired cable or adapter between
the processor and the amplifier channel.

NOTE:
For VRX932LA systems in passive mode use the suggested Xover For Sub filter as is and adjust the subwoofer gain for desired performance.
For VRX932LA systems in bi-amp mode use the suggested Xover For Sub filter settings and implement it to your matching bi-amp fullrange table.
