Your settings are nothing like what's in the video nor what's in the manual. I'll try what you have and keep adjusting til I get good results.

Your settings are nothing like what's in the video nor what's in the manual. I'll try what you have and keep adjusting til I get good results. A few things about my setup. My 13A's are powered by lower gain tube amps, so that's what I start with in the Volume Calibration. They stay a 100%, I arbitrarily set the mic to around 75% or a little less (I've been trying different gains here). Then the Master Volume is raised so the sound level is brought up to -24dB to -25dB. I want Master Volume to be high enough, but not so loud as to be as loud as what a movie would be. The actual volume during measurements is in the low 90dB SPL range, so it's pretty loud. I plug my ears. The Volume Calibration level for the subs is set to 100% - but be cautious here. I set the LFE volume knob on the subwoofers to zero. Then, when the sweep is played I turn up the gain knob on the sub to adjust level to match the other speakers. All the other speakers are set the usual way by using the sliders to adjust. I set the slider very low, then press play to sound the sweep. edit: To make the measurement sweeps louder when measuring you make the Master Volume level higher and Mic level lower. They are relative to each other. |

I still can't get a measurement result no matter what combination I've tried so far but will keep frustrating myself until I get something to work. Thanks to all who are contributing.

Did you bring the Mic slider down to around 75-80% ? This effectively raises the actual output of the pink noise so it overcomes ambient room noise by enough. |

Bring the Mic slider down so the Master Volume can be higher. This is important. You need the sound level higher to your ears.

OK. Willl try that shortly. I got some different errors (will get screen shots next time) and had to reset the dirac hardware box and restart a few times. It was quite loud at one point but I still got the low signal to noise level error.

The only screen shot needed really is one which shows the Master Volume so that'll include out to your Center Sub.

Still no luck. Round 1 Screen shots. Still the same error  |

looks like your mic needs to be turned up closer to %100 |

Sorry, just saw your response on the screen shot to send. Will do that next time.

The problem with turning up the mic is the overall volume is LOWER. Not good. Your problem is probably something else. Please list which speakers are set to Large. Are you using Width for anything? Also please list exactly how your subs are setup using the Menu headings. Mine are Dual Mono.   |

Bring your speaker levels up to be closer to -16db instead of -25.
For troubleshooting, bring the mic up to 100% to eliminate that element. Play all speakers to find your lowest playing speaker and raise your master volume to bring it up to -16 db. Then lower your remaining speakers to bring them to -16db. For your subs, you might have to manually bring their level up or down with their gain knob.

Speaker setup can have an effect on Dirac not "seeing" a speaker properly. There's a known issue with setting Left/Right Subs to Mono and Dirac is not aware that there should NOT be a Right Sub and tries anyway and gives a Noise Error. That's why I was asking about speaker setup. Try what Nick suggested. Also see below. See the attachment for a progression of setting the sliders. My Right and Left Fronts are the weakest volume so their sliders are always at 100%, and everything else is adjusted down from there. Going from left to right the speaker volume sliders are adjusted without moving the Master Volume or the Mic sliders. The Subwoofers are adjusted by a different method and that's why they are also at 100%, I have adjusted the gain knobs on the subs to a lower value.  edit: Please note that even though the Master Vol and Mic sliders never move - the dB's shown will change based on which speaker is sounding at the moment. I made these screen shots while the pink noise was sounding, so this is why the dB's on previously adjusted sliders "seems" like it's different from slide to slide. |

My two front left and right speakers are set to Large. They are Martin Logan Summit's. Everything else is set to Small. My left/right sub is set to Dual Mono. My center sub is set to Mono. I'll try again tomorrow. I'm frustrated out for the day. I didn't have these sort of issues with the XMC-1 and Direct Live LE.

kbuggs FYI Dirac 3.0 had problem with Noise. If you downloaded Dirac recently you probably have the "current" version which fixed the problem. I only bring it up just in case it's the older version. Current version is 3.0.2.

kbuggs You know what? Maybe just setup Preset 2 for a simple system until Dirac can get past the Measurement tab. Fronts Large Center Small Center Sub Mono Just to make it quick to check things. This is what I've been doing the last hour or so while moving my subs around, exactly the configuration above.

I've actually got the system sounding very good but figured Dirac may make it better. Greed I suppose. I like your suggestion and will take it and see if that allows us to narrow it down to an equipment issue (microphone, sub, digitizer, etc.).
Great call-out!!!

The pink noise is "fairly loud" correct? In other words, it would be difficult to have a conversation while it's sounding. |
