I know that many of you on this board has experienced this,but I wonder if there was any official "reaction" from the Outlaws. I did a search and came up with nothing. The analog xover was one of the main reason I bought this unit,so it's kinda important to me.I use passive subs with pro amps,and they don't have any type of polarity switch on'em. So what's the word?

If it's actually 'reversed' you really don't need a polarity switch, do you?

When the sub is out of phase with the mains........then yes some type of fix is in order!

If using an outboard power amplifier, the easiest way to regain proper polarity would be to simply reverse the speaker leads at the power amp binding posts. ------------------ The Soundhound Theater

Hun- I guess a slightly better way of putting this is: If you adjust the mains to be in phase with the sub with DD/DTS/CD digital signals with the digital crossover in the 950, then it will be out of phase using the 6 ch input and the 80 Hz analog crossover. I just see this as an example of the $899 price. I just change to the inverse polarity input on my sub when I play DVD-A and SACD material.
Oh yeah, a strange observation. I have a std and inverse input on my sub, along with a variable phase knob. For me, it is easier to just switch from the std to the inverse input. OK, so I bought an A/B switch to do this. Now, the A/B switch is really supposed to be for switching between 2 components input into one input. So I'm kind of using it in reverse: 1 component to switch between 2 outputs.
When I hooked everything up, the position of the switch didn't matter! Instead of easily seeing in phase vs out of phase signals between both positions of the switch, I got no difference at all. Either a bad switch (but something like this is so easy, that that doesn't really make sense), or I'm not understanding how one of these guys operate. Never did get motivated enough to open it and take a look at the wiring. I have another kind of A/B/C switch now someday I will try... (Position C for no sub, for 2 ch bypass where the 950 also sums the bass to the sub if the speakers are set to small.)

It's only happening when I use the the 6ch input [listening DVD-A MC]. In all other operations it's fine. So I would have to pull out my amps and reverse the speaker cables,anytime I pop in a DVD-A disc? You kidding right? Kevin, I felt I didn't need to explain the whole scenario as it was discussed several times here before,looks like not everybody read it. I don't think that this problem is oK for the $899 price, and I doubt the the Outlaws would agree with that "philosophy" either. Was there any "acknowledgement" at all by them?

When it's in phase in 2.1 (stereo+sub), it's out of phase in 5.1 (DTS NEO/DPL II) in my system.

Perhaps if you are handy with a soldering iron, you could build a simple phase inverting stage for the 5.1 SUB output. All that would be required would be a TL071 op-amp and two 10Kohm resistors, not including the power supply and box etc. These parts could be purchased at RadioShack. ------------------ The Soundhound Theater

If you're inclined, you could connect your subs to the amp with banana plugs and easily flip them over when listening to DVD-A. It would be almost as quick as flipping a phase switch.

My Crown amps use Nutrik connectors only!
