Cool thanks stereodude. That would save me $ also because ARC 2 or the Dayton system both sell for $299...the mic is less than a buck, IIRC...

MFREY, you have to buy a mic and measurement program (REW is free), they do not come with the miniDSP or it's plug-ins.

Ok that's what I wanted to know, if I bought just the calibration mic, could miniDSP plot Freq measurements like a room calibration program...but if REW is free then again it will save me $ because I only have to buy the miniDSP and a mic, instead of the three hundred dollar all-in-one room calibration systems.

I Have Omnimic with Software Version 3.+, what is new in 4.0. Any thing new? My miniDSP shipped from Singapore today..

Thanks.

Well, you do need the associated hardware to go with the mic, like a USB sound card with mic pre-amp circuit & phantom power.

Um, OK, all I have is my laptop A Toshiba Satellite A215-S6816. I have 3.5mm jacks for mic and headphones, and regular 2.0 USB ports. I do not, to the best of my knowledge, have a port that is USB and specifically for USB mics.

So if I get the Dayton Audio OmniMic V2 Precision Measurement System HERE, then I can just plug right into my laptop? Or do I still need a soundcard upgrade, preamp circuit, and phantom power?

EDIT: Nevermind, found the answer. It looks like with the Dayton package all you need is an active USB port...

Installing the OmniMic V2 Hardware:
Plug the OmniMic V2 into any unused USB port on your Windows computer. When properly connected to an active USB port,
the "Blue" LED on the OmniMic V2 will illuminate. The OmniMic V2 software will look for the microphone’s presence. If the microphone
is not connected to an active USB port, the top of the OmniMic V2 window displays the message "OmniMic not found."

My comment was based on the assumption you were referring to a microphone with an XLR connector on the back like an ECM8000 or EMM-6, not an all in one USB microphone like the Omnimic.

If he had gotten the balanced version he might. Dealing with those "Phoenix" connectors is a royal pain in the butt. Although it gave me the chance to make these lovely cables it wasn't something I really was dying to do.

post #1121 of 2293
So was I understanding the 10 x 10 HD box right, I can run all my 7.1 analog out of my Onkyo 609 and into the minidsp, eq each channel separately, and from the miniDSP to the speakers? Or is that only with something else involved in the signal chain, like a dedicated amp? Yeah, how would the miniDSP handle the amplification from the AVR, would be my first question...
post #1122 of 2293
You will need to connect the outputs of the miniDSPs to amplifiers.
As for Phoenix connectors, I think they are difficult too.

Or if I had an AVR with 7.1 analog input, would that work?

No it wouldn't unless you're referring to using a 2nd AVR with an analog 7.1 input as an amplifier for your system.

Right, of course...As a newb, I'm just trying to visualize the signal chain in my head...

(1) Source > (2) AVR > (3)miniDSP > (4) Sub Amp > (5) Sub...

So a dedicated amp would be placed...where? Between 2 and 3?
post #1126 of 2293
No the sub amp is the "dedicated" amp.

Sorry, I'm not making myself clear...I'm talking about a "what if" where in the future I add a separate amp into the chain for the full range speakers, instead of merely driving everything but the sub with the Onkyo.

Which also got me wondering about how, again in the future, if I wanted to use the 10x10 HD miniDSP (if it's even possible) on all 7.2 channels in my HT setup, where in the chain would I need to place the miniDSP?

Then that got me thinking about decoding...like, for instance, if I have to run the signal from my Onkyo AVR to an amp, how do I maintain the signal from, say, a Blu Ray encoded in Dolby DTS Master HD? Doesn't everything get downgraded to analog 2 channel in order to run a signal from the AVR to an amp?

Or am I totally confused? If so, I'll bow out and stop clogging this great thread...tongue.gif

I use a miniDSP to crossover my DIY speakers. It goes between the pre-pro (or receiver's pre-outs) and the amps. So its pre-pro-->miniDSP-->amplifiers-->speaker drivers. I have one amplifier channel for each driver in my fronts.
I have the older and less expensive "miniDSP in a Box" not the 10x10, although the 10x10 would also work.

How many speakers are you driving total? I assume with this setup you would have no use for the Audessey controls on the AVR (if it has them)?
post #1130 of 2293
I do use Audyssey. My front speakers have one mid-woofer and one tweeter each, six total for the L/C/Rs. I have two subs also using miniDSPs. I use a total of three miniDSPs.

Hi,

Just received my mindsp. I have 3 subs, hence, i went with 4 way crossover adv. I have omnimic with 4.02 version which can now work with minidsp. From Omnimic's manual, I can create the file for minDSP, BUT,

I down loaded the plug-in and opened it and I am completely lost. Can somebody be kind enough to tabulate/list the steps I need to go through to set-up the miniDSP... Please.

Thanks in Advance.

Just got my miniDSP today! Wow, hooked it up to my laptop and I love the options, Q up to freakin' 50?? Sweet...

All the options are currently boggling my mind...like...6 band PEQ both on input channel and one each per output channel?? Ha!

I can't even begin to comprehend the possibilities with this plebeian grey matter I possess! Who shall deliver me from this paralysis?? biggrin.gif

post #1134 of 2293
I am currently happy just using this version to power one home made subwoofer. However, I am rapidly starting to feel like I'd rather use a miniDSP to EQ all my speakers instead of just the sub.

So...

What do I need? The 2 x 8 version? I have an Onkyo 609 7.2 channel receiver running a 7.1 setup. No amps or preamps, just the AVR.

How do I make sure I still get the proper signal from my Blu Rays? For instance, if I'm watching something in DTS MASTER HD 7.1, how does that get to the speakers using the miniDSP? Wouldn't it only be relegated to 2 channel when running the signal from the AVR to the miniDSP and then to the speakers?

Now, as far as just dealing with the device I have now, is there a preference as to power supply? Is there any advantage, distortion or voltage wise, in using a DC power converter instead of a USB cable?

Should I be using the .9 or 2v configuration?

Since my receiver has 2 sub outs, would there be any benefit to running both to the miniDSP and then either an RCA y splitter or single output to sub?

Would there be any benefit to using the low level inputs on my sub amp versus the LFE? If I use the low level, won't I lose the .1 track info on my audio?

If you want to EQ ALL your speakers you will need the 8x8 kit AND get an external amp. The MiniDSP will not be able to power your speakers itself and you will not be able to use the amplifiers in your AVR. If you want to use you the MiniDSP then your Onkyo will act only as a processor.

Your current sub configuration will be fine. You do not want to plug both LFE channels to the MiniDSP. You cannot combine the signal anyway. Each of the inputs on the MiniDSP is for the respective outputs. CH1 in --> CH1/2 out, CH2 in --> CH3/4 out. I'm assuming you meant to ask if you wanted to use the high level inputs on your sub instead of your low level inputs. Low level is the RCA connector. That is what you should be connected to if you are using the MiniDSP. The high level input is if you have no dedicated LFE channel and are running the signal from your L/R speaker outputs from your AVR. If you use the high level inputs from the AVR L/R speaker channels you will lose all your LFE .1 channel information unless the Onkyo can be configured to mix the LFE channel into the main channels.

OK, tks for the info, duc...question though, why would I need a separate amp if my AVR is putting out 100 watts per channel? Can I just run the 7 analog speaker wires from the AVR to the 8 x 8, and from the 8 x 8 to the speakers?

I really like this thing. Already set up a high shelf/low shelf for the 30hz spike...

Anyone comment on whether or not I should stick with the current .9v config or go to the 2v?

The miniDSP is a LINE LEVEL device, not a speaker level one.

Right, we already covered that, didn't we...has to be put in before amplification...

You seem to have quite a bit of confusion. You CANNOT use the AVR you have to eq the speakers. You don't have any preouts for the speakers.

You can however eq the subwoofer ONLY using the subwoofer preouts. Look at the purple connections on the back of your AVR. Those are the subwoofers preouts. Normally you would connect your subwoofer (subwoofer amplifier) to those subwoofer preouts. What you need to do is connect the subwoofer preouts to the Minidsp THEN connect the Minidsp to the subwoofer (subwoofer amplifier).

Hi Mfrey,

To add to what LJwelr said, you can't use the miniDSP for the other seven channels at all with that particular Onkyo. Separate amps wouldn't help.

The problem is that it has no line-level outputs between the point where the audio is decoded into multi-channel and where 100 watts of audio finally exits at the speaker terminals. So there is no way to get line-level audio out of the Onkyo to feed to the miniDSP.

If you could get the decoded audio to the inputs of the miniDSP (if the AVR had pre-outs), you would then need to feed the outputs of the miniDSP to amplifiers. That is where you often need additional amplifiers, as not many AVRs have separate line-level inputs to their amps.
