I'm still in the process of planning my install. I will be keeping the stock head unit in my 2015 F-150 and will be using an Audison Bit One to take the high-level outputs from the stock Sony amp/DSP prior to sending a somewhat clean signal to my JL Audio HD900/5. I really want to achieve an ambiance effect with the rear speakers and was initially planning to go the modified RCA cables route. I was planning to do L-R on the left channel and R-L on the right channel. Then I had a thought. Since I'm using the high-level inputs of the Bit One, why not invert the channels at the high-level inputs instead of at the amp inputs? Seems logical and easier than having to modify RCA cables. The only thing I don't know is if the Bit One is capable of inputting and outputting discrete channels (pass-through), or if it will simply sum all the channels that are inputted and then allow you to output discrete channels.

What I need the Bit One to do is sum channels 1 and 2 for a left side full range signal, 3 and 4 for a right side full range signal, and then allow me pass-through channels 5 and 6 (un-summed) for the rear ambiance. I still need the Bit One to de-eq channels 5 and 6, be able to tune them, and apply time alignment. Does anyone familiar with this processor and it's software know if this is possible? I've never used the processor or the software before and cannot find the answer in the owner's manual. Any help would be appreciated. -Pablo

I'm not familiar with the Bit One but I have played a lot with my DSP and crude summing the LR to output to the rears. I ran both rears mono for a bit and while to did add ambiance it caused a mudding in singers voices. I really needed to have them separated to their original L-R signals and apply timing accordingly. Can't say thats the case for everyone but in my setup I was not pleased summing the rears. Sounded better to not have them at all then not tuning them accordingly. Long story short, I'd rather have no rears than not being able tune each.

i just got home from work after wrapping up tuning a car utilizing l-r/r-l rears using the helix for the first time. i definitely like it. curious how you do this with rca's though..

From what I understand, to achieve l-r/r-l with modified rca cables, you use L+ to positve and R+ to negative on the left channel, then R+ to positive and L+ to negative on the right channel. You would need an amp with balanced rca inputs to make this work. Seems like unnecessary work if I could somehow manage to get the Bit One to accept this setup as high-level inputs and send it straight out to the designated outputs for the rear channels. I'm afraid that the Bit One is just going to take all my high-level inputs and sum them up. I hope that's not the case. I'll be playing with it this weekend so I'll let you know if it's possible, unless anyone else chimes in to confirm/deny if this DSP is capable of this.

MORE details please...where in the software is this located??

in the input matrix. for the rears, you drag and drop both left and right full range onto one of the rear speakers. lets use the left side for example. now when you do this, you will see left is at 50% and right is at 50%. since your doing the left rear speaker, double click on the Right Full Range signal that you dropped, and click invert phase. repeat vice versa for the other side. your pretty much summing as mono, then flipping phase of the opposite side

+1, I'm also curious. If the Helix software can do this, the Audison might be capable of this too. I know the Bit One software has an option to invert a channel before outputting it to the amp but I don't know if it's capable of outputting this weird inverted l/r summed signal I'm trying to achieve if I just fed it a normal stereo signal. That's why doing this summing/inversion at the high-level input seems more logical, but I doubt it would allow this signal to go through unsummed with the other high-level inputs.

I wonder if this would output a true l-r signal. It seems logical but differs from the modded rca cable method I mentioned earlier. Or maybe it doesn't and my brain isn't processing this software method correctly. Doesn't hurt to give this a try on the Bit One software if it allows this drag/drop method you speak of. Thanks for the tip.

I tested it last night with the 7 drum track. It works

Don't think the Bit One has an input mixer that can do that.

Well that doesn't sound promising. I have the software just haven't installed it. I guess I know what I'll be doing when I get home from work. I'll post what I find.
