"Can this unit run several separate subs with separate responses from one Mini"

yes.

Thats too cool...

Been reading this thread for some time now.

I'm thinking about using two 8x8's for room correction on my 9.5 channel system going into my new room. Can anyone see any problems / limitations with this ? The other option (QSC) that's been suggested is about 10x the price !

It's a shame they don't have an 8x8 in a box.

Cheers,

Seems like it should work well. There was some discussion about an 8x8 in a box, but so far nada...

Hi,

We will be exhibiting in THE Show Las Vegas (same time as the CES) a new pair of monitor speakers from Japan that use miniDSP boards as active crossover and equalization purposes.

For those of you who interested about miniDSP and REW, it might be a good opportunity to meet if you were planning to visit Vegas next week.

Best regards,
Cedric Segal

Peter M, why not a 2x4? Save some money and get a case that way...

Surely 2 of your 5 subs are co-located and can share an output.

Pretty sure because he wants to use them on a 9.5 channel system

I'm currently using one 8x8 for room correction with 7.1 channels and it works great.

I have seen pictures of an 8x8 in a box but have no idea when it will be available.

Ya, but like I said, as long as its just to eq his subs, likely 4 channels of eq is adequate. If the cost and box matter enough. Likely cost not the issue on a 9.5 system.
post #851 of 2293
Thanks for all the responses. My 5 subs are all in separate locations so I'd like individual control. The 9 channels are the normal 7 with the sides doubled for the two rows of seating. I'm also thinking of 4 x DCX2496 which doesn't come out much more and at least there's no fiddling around with boxes / connectors etc. Decisions, decisions ...

Cheers,

For a 3 or 4 way speaker design should I just use the 2x8?

ANd what plugins?

I have never really looked to much into this because I was to busy with designing subs. But these will be for a L/R 3 or 4 way design. Most likely a 3 way design.

Just want to make sure I order the right one when the time comes and make sure I know what the budget needs to be.

Thanks.

I think I will just look at Not's thread and put mine in a 1U box so I can store it in my rack.

new FIR filtering platform

When it's a 2 in and 6 or 8 out xover/EQ unit it will be far more interesting.

Ditto. Or better yet, a 3-in/6-out, so one could do LCR's with one box.

Stupid question, but is it worth having an amp with controllable gain on it? Im about to pick up a used LPA-1 to power two 3 way speakers with my two minidsps. Im guessing you can control levels just fine in minidsp so unless i want to "tweak" things like tweeter volume without hooking up the minidsp buying an amp with no controllable gain on it is fine.
post #857 of 2293
OK - I just finished reading 25 pages of this thread, whew.

My situation:
Yamaha RX-V1065 Receiver with 1.0V preout
Crown XLS5000 amp (sub use) which requires 1.25V for full tilt @ 4 ohms
Currently using a cleanbox pro to boost output which works great

I do want to buy a MiniDSP but I'm torn between buying the balanced and making connectors, etc vs. buying unbalanced and using my cleanbox pro with it.

I guess I wasn't clear if the MiniDSP balanced version will actually BOOST my voltage to 2.0V or it will simply just pass through whatever it receives up to 2.0V. If it actually does increase the voltage (which it seems it might) getting rid of the cleanbox would be pretty sweet and I'd clearly choose the balanced version.

TIA,
Andrew
post #858 of 2293
I'm sure someone here can confirm that for you, but I just purchased a Balanced 2x4 miniDSP for the same config - Denon AVR to a QSC amp. The input sensitivity on the miniDSP Balanced is selectable via dip switch (you can change the input sensitivity range from 2v to 0.9v, if needed), and it will output a standard balanced signal to the pro amp. Based on my understanding, you shouldn't need the cleanbox.

I'll let you know for sure once mine gets here and I get everything setup, but if I'm wrong, I don't see why they would even sell an unbalanced vs. balanced version w/ reconfigurable input sensitivity.

This review would seem to confirm my understanding: http://www.hometheatershack.com/foru...dsp-howto.html
post #859 of 2293
Blackcat - thanks a ton for that link. I will likely order the balanced version to give it a whirl.

Is it possible to run OM and MiniDSP at the same time, split screen on my laptop ?

I've run FuzzMeasure and the 4-way Advanced Plugin at the same time on my MacBook. One would assume similar things are possible with other OS's, so long as you have multiple USB ports.

Cool, it would avoid stop and go adjustments....
post #863 of 2293
I guess i sould ask before it gets here, creating a filter with a lowpass at 40hz and a hipass at 80hz for my AUX sub, how would that be done, almost sound like a midrange type bandpass. I almost want to avoid the hipass not to interfear with the receivers 80hz XO.......i think hahaha

...oh, and which on do i want for an active XO... Not sure i understand the diff

You have your terms backwards. You want a HP at 40Hz and a LP at 80Hz. If your AVR supplies the 80Hz LP for the LFE out, then you won't need to add it with the MD.

Ok the hipass is 40hz... Now that i think of it the speakers are set to 80hz, but the LFE is 120hz..... I think i may want to LP@80hz so it has a speceific bandwidth
post #866 of 2293
OK, I have read the whoole thread and think I'm more lost than when I started, so I appologize if I missed something. I have a denon avr 3311, emotiva xpa 5, left, center, right, and two surround speakers, and a sub. I am wanting to add another sub off existing lg amp, and eq those independently of each other, and also eq at least my left and right front speakers. If I use the 4x10 plug in I can keep 96khz. Could I use the digital output of my avr for the left and right channel and then analog for my subs? If its not possible then I will just use the 48khz 10x10 plugin. Thanks!

i seem to be confused on what DSP to get REV A or REV B for my subwoofer project..
One LFE in, and three sub out's ........

The only difference between them, is that Rev B has an attenuator at the input so that it needs 2V for max output, and A needs 0.9V because it has no attenuator.

You need to know what level signal you will be providing to decide exactly, but if you can't/won't measure, then B is likely safest choice.

I could be wrong, but I thought it was the other way around.

Either way, info is at MDSP site, somewhere.

You are incorrect. I know the chip used and how it works and is specified.
