Hi All;

I know a few of us use the 260 and I wish to experiment with the phase compensation portion of it however I can not get it to make any difference. Here's what it says on page 38 of the user manual for the 260 in section 4.12

"The output section 480, 481 and 482 DriveRack units provides the user with the ability to control output levels of the unit and adjust phase compensation of loudspeakers within the signal path. The output level control is located in the signal path before the compressor/limiters; this means that the compressor/limiter directly affects the output level. The parameters for the Phase Compensation effects are as follows and are adjustable.

Shift On/Off
This parameter is used to turn the selected output phase parameters on or off. When level is off, phase is zero degrees and polarity is positive.

Polarity On/Off
This parameter is used to reverse the polarity of the output signal.

Phase 0 to -175 degrees
This parameter sets the amount of phase within the selected output path. The phase is referenced to the upper frequencyof the selected output crossover band. "

OK, one thing jumps out, the fact that it says "The output section 480, 481 and 482 DriveRack". Well this is in the 260 manual AND when you are connected to it via GUI with the crossover page open, you double click on the channel of interest (1-6) and the menu group opens just like the manual say it will.

So far so good, you can toggle on the shift swith and flip the polarity and it works (measurable and audible), I can also slide the phase button however it has zero effect. I finally routed it (the 260) straight through my TEF for a electrical only transfer function measurement and can read zero shift at any frequency.

No one on the DBX Forum could answer this and referred me to ProSoundWeb. I have not poised the question there as yet nor have I called DBX Tech.

Anybody know if this is a functional parameter within the 260? It would be VERY cool to be able to insert a sloped correction for group delay into my subs!
