So, as jcmccorm knows, I am pretty much mirroring his build, albeit with different positioning of the enclosures in my room. That said, I'm getting ready to order the electronic components to go along with the enclosures that are under construction and want to ensure I am getting the correct connectors, wall plates, and enough wire. Here is my understanding on hookup of the four enclosures (4 8 Ohm enclosures resulting in 2 enclosures wired in parallel to present two, separate 4 ohm loads) to an NX6000D:
1) Yamaha AVR LFE Output 1 to NX6000D Input Channel A via single RCA (male) to single XLR (male)
2) Set NX6000D to BIAMP1
3) This is where I have questions, the NX6000D manual uses a traditional hi/low bi-amp configuration as an example, which is not what we are doing. What is confusing is their example describes the ouput as all done via Output Channel A and a 4-pole speakon, but then goes on to say that the low frequency output uses Channel B, 2+/- and the high frequency uses Channel A, 1 +/-, even though it only describes using Output A. So, here are my questions:
3A) Does the BIAMP1 setting combine the output from A and B all into Output A and then split it between poles 1 and 2 within the speakon (i.e., the physical Output B connector is not used)? This is confusing because I always thought that biamping took a single input and split it into two separate output channels (i.e., Input A crossed over to send high freq to physical Output A and low freq to physical Output B), but this is not at all how the manual reads.
3B) The manual describes setting the crossover frequencies for Channels A and B based on the traditional bi-amp (high on one, low on another), but I assume for our application, we are just setting low on both and that the amp does not prevent identical crossover settings for each channel?
3C) Assuming one physical output like the manual describes, the amp is then placing output channel A on pole 1 and output channel B on pole 2, so, I would need to split the 4-pole output into two 2-pole outputs, with each of the 2-pole outputs then being split in parallel, one to each enclosure, correct?
Now, here what how I THOUGHT it was supposed to work:
Using LFE input to Input A, set amp to BIAMP1, set a LP crossover (e.g., 80 Hz) for both Output A and B, then run a 2-pole speakon out of Output A and another 2-pole speakon out of Output B (I would then split each of the individual outputs via a parallel speakon, which would give me the four total outputs, one for each 8 Ohm enclosure)
Obviously, depending on how the amp handles this, it will really affect the quantity of wiring, connectors, and wall plates I need to buy, not to mention how I build the speakons.
I appreciate your help!!
