So I know which ones are which, what I need to know is: Can I use both the RCAs and the speaker level ouputs at the same time with 3-way NW turned on (in other words, biamp a pair of speakers with the internal amp). My goal is to power a rear fill pair of speakers so I don't have to buy another amp, space is very tight in my rig.The unit has a switch on side of the chasis where you can select NW or STD. NW = Active mode and STD = passive mode. You would need to press the reset button everytime you change the mode.
In STD mode you can set the xover point for your sub LP and your mid HP. The passive xovers on your speakers would split the signal between the mids and tweets.
IN NW mode you can set both the sub/mid and mid to tweet xovers from the HU. This would apply even if youn were using the speaker level outputs i.e. no external amps. You would remove speakers passive passive xover and connect the drivers directly to the units speaker level outputs.
Hope this answers your questions.
Interesting, I had not seen that PDF before. That diagram makes it look like you can only use one or the other and not both.http://www.pioneerelectronics.com/StaticFiles/PUSA/Files/DEH-P800PRS_InstallationManual12010.pdf
Figure 5 tells you how to wire them....
