So your saying use xlr cables for output?

Yeah, he is but i'm not sure if it's a requirement for the input. I don't think that it is as I think that it somehow converts it to a balanced output. For the time being if you don't have xlr cables then use some cheap rca's that you have lying around. I have mine connected that way for now and it's enough to drive my crown into clipping.

For the output yes.

Gotcha. Thanks.

The picture shows a shielded two-conductor cable, while the standard RCA cable is a shielded single-conductor. For that, the RCA’s red (center) conductor goes to the Phoenix (+), while the shield goes to the shield screw with a jumper over to the (-).

Perfect, Wayne. Thank you.

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?

You only need to connect one of the sub pre outs to the minidsp. They are the same signal.

are you sure the on the AVR8801 they are discrete channels? At least it looked like audyssey calibrated them separately. Maybe not.

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.

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).

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.

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?

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.

2.1 advance flow chart. http://www.minidsp.com/images/documents/Product%20Brief-%202way%20Xover%2021%20ADV%20plug-in.pdf

Correct. In doing this your are sorta turning a 2 way advance into a 4 way advance.

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...

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.

The 8801 has XT32 and SubEQ. That said, your explanation makes sense, thank you.

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!

u could buy one of these http://www.speakerpower.net/

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.
