For the output yes.

Gotcha. Thanks.

Perfect, Wayne. Thank you.

Both of these statements assume the input jumpers are on the 2.0V setting.

FYI- I changed to a balanced cable on the output side and now its back to being how it was without the minidsp....crisis averted.

Looking at getting a mini-dsp for my subs. I am currently running a Marantz AV8801 as a Pre with an outlaw audio amp. I have two subs currently running in my room. Which mini DSP do I need for this setup? I eventually will be running 4 identical subs but they will be sharing channels. I will be powering the subs with a LG clone. Which plugin should I purchase for it to? Thanks for the suggestions!

Ability to provide separate EQ, level control, and delay for each subwoofer.

I would start by not having the subs share channels. The degrees of freedom one gets by being able to vary individual level, delay, and to a lesser extent EQ make system optimization much much much easier.

I went with the 2x4 Balanced kit with the 4 way adv plugin. I am assuming I can connect the 2 sub out puts from the back of the AVR to the minidsp. Does the software allow me to choose which sub gets which input from the AVR?
post #1329 of 2293
You only need to connect one of the sub pre outs to the minidsp. They are the same signal.
post #1330 of 2293
are you sure the on the AVR8801 they are discrete channels? At least it looked like audyssey calibrated them separately. Maybe not.
post #1331 of 2293
Who manufactures the 8801? Which version of Audyssey do you have?

I haven't been following your posts but yes MiniDSP will allow you to pick what input belongs to what output.

Marantz, xt32

Ah ok. That's a different story. Audyssey in Your avr treats each one separate. So yes, as Audiophile said. You can choose each one in the dsp. You may also want to try using just one output as well just to see any difference. I know Gorilla83 did it that way for some reason and he has xt32.
post #1335 of 2293
I don't think XT32 invariably means separate EQ for both subs. I believe it also needs Audyssey Sub EQ HT (which the 8801 has).
post #1336 of 2293
Lots to play with when it arrives! From what I have read use the MiniDSP before running audyssey. Can anyone confirm this?

Not with the 4 way advanced plugin. Only with the mixer. The 4 way takes both inputs and sums them. Then sends the same single to all 4 outputs. Like what you would want with a 4 way speaker. Now the 2 way advanced plugin input 1 goes to output 1,2 and input 2 goes to output 3,4. This is the plug in I use with Denon 4311 with separate sub outs. Just email them and they will switch plugins for you if you decide you don't want it.

OK, I am assuming that is probably what I want since I will only be running subwoofers with the minidsp. Would there be a reason to want the 4way? Seems strange the 4 way plugin does not do the same thing as the 2 way.

The 4 way is just fine if you only have one sub out on your AVR. Take a look at these audio flow chart diagrams. This is the easiest way to tell which one is right for you.

4 way advanced. http://www.minidsp.com/images/documents/Product%20Brief-4way%20Xover%20ADV%20plug-in.pdf As you can see it sums the two inputs.

2 way advanced. http://www.minidsp.com/images/documents/Product%20Brief-%202way%20Xover%20ADV%20plug-in.pdf As you can see it keeps the inputs separate. Input 1 goes to output 1,2 and input 2 goes to output 3,4.

Mixer. http://www.minidsp.com/images/documents/Product%20Brief-Mixer%20plug-in.pdf This one keeps the two input separate until the final step where you can mix what inputs go to what outputs and at what levels. Most people would never get this one because of it not being integrated with REW and no PEQ or biquads.
post #1340 of 2293
I am assuming if I ever wanted to run one sub input to multiple subs I could 'Y' one out put from the receiver to both inputs on the minidsp. Is that correct?
post #1341 of 2293
The 2.1 Way Advanced plugin is the same as the 2 Way Advanced except it allows for summing the sub outputs.

Input 1 -> Out 1 and 3
Input 2 -> Out 2 and 4

OR

Same as above except Out 1 and 2 are summed mono.

Correct. In doing this your are sorta turning a 2 way advance into a 4 way advance.
post #1343 of 2293
Curious: Is there any reason to add a miniDSP to an 8801? Seems like it already has plenty of correction for the sub... Seems like the miniDSP would be more a geek toy, not that I would let that stop me from getting one... smile.gif
post #1344 of 2293
Depends on the specific situation. The Q on my AVH build was too high and I had to use minidsp to apply an LT. Once the F3 got low enough Audyssey could do its thing. And even if that were not an issue, eq can get you flatter response than most flavors of Audyssey can. Or you could add a house curve. Or high pass it to save headroom for more output. There's a world of possibilities.
post #1345 of 2293
The 8801 has XT32 and SubEQ. That said, your explanation makes sense, thank you.
post #1346 of 2293
I have a few questions about the shipping from HK to USA:

1. Can anyone tell me if the shipping method used by miniDSP delivers straight to your door?
2. Who is the currier once the products reach the states? USPS doesn't deliver to my home, so I need to know if I should have the item shipped to my physical address or not.
3. Do we need to pay import tax and what does this process look like? I'm planning to order a plate amp so the price is much higher ($1000) than the average miniDSP products.

Thanks for the help!

i have a 8801 and i still plan to hook up my mini dsp in between the 8801 and my amp

mainly to smooth my sub out a bit before i try audyssey, that and i need a crossover for my buttkickers.

I've had my eye on the sp1-4000, but the end user versions don't have DSP built in, so it would cost quite a bit more in the end ($1300 plus the price of DSP). Definitely a better amp than the PWR-DSP1, but I'm already over budget.

If anyone can help with the questions I posted above it would be really helpful. Thanks.
post #1350 of 2293
I'm actually going to do miniDSP calibration after audyssey in my av8801.

fix a couple of nodes audyssey didn't quite get rid of, and most importantly, add that needed L/T to boost the low end.
