Dirac is good technology but some problems cannot be fixed by Dirac. Room acoustics and speaker issues are on the top of the list. Microphone accuracy is not always good and they measure sound differently than we hear. Humans are very good at distinguishing and filtering direct and indirect sound. Dirac is a one speaker at a time optimization. Combing issues when multiple speakers interact are not addressed. I chose to buy well engineered speakers with flat response and without off-axis anomalies off, tol imit correction to bass frequencies. That also is not really necessary because my room large enough and my seating position is not close to a boundary or a particularly bad room mode. Dirac multi-speaker bass management has real potential because it concentrates optimizing bass frequencies using multiple speakers. - Rich

Having read the manual just once but taken it all in, I am quite excited about this implementation.
It does everything that Dirac Live for the XMC-1 does yet better in many regards and worse in none.
Yes, still 24bit/48kHz - I can live with that Yes, the Dirac Live Bass Control is not (yet?) an option Yes, there is a network interface box and ethernet switch to set up for the measurements but I'm into Home Theatre and Audio so that is well within my skillset and intellectual ability.
But: Optimisation is now possible for a narrow field main listening position (Either for a solo listening experience or if you don't think your partner will notice (or care) that they are off axis.) And: Additional options for Narrow or Wide sofa / seats arrangements for those that want to choose between 100% optimisation for one person, 95% for two people and 90% optimisation for 90% of people in a multi-seat environment And: Dirac can be applied to both speaker presets (All Large or All Small or Stereo Front or Atmos or whatever And: Three filtersets for each speaker preset to finetune depending on seating position, listening field width, different emphasis/curtains And: Dirac across 16 channels rather than the XMC-1 7.2 Ch And: A hopeful possibility for Dirac Live Bass Control integration in the future. In the meantime at least you can choose between up to 3 subwoofers to get an independent Dirac filters for each solo subwoofer room response, or you can Y-cable/daisy chain them together for a combined attempt at a Dirac filter. Neither is ideal but you also have the option to not apply a Dirac filter to multiple subs by moving the curtains and use an external sub-only equalisation.

I’ll probably read the manual after I get the hardware and the license.
Then I don’t have to read the manual twice. 😊

Are most of you going to do two setups, one for solo and one for when there are others watching with you? I’m not going to lie it was a little overwhelming on the first read through, lol.

What makes the whole process easier is getting a cheap microphone stand with a horizontal boom. For a few pounds it makes the task easy and accurate -
No crouching and ducking and hiding from the speaker / microphone No errant rustling from holding the mic.

I took a quick look and I’m not sure how Dirac’s delay and levels are saved. I just looked at the Monoprice manual and they even give a user adjustment to both the level and delay for each of their 6 presets. Shouldn’t the distance and levels be under each preset? Dirac 1 Distance Level Dirac 2 Distance Level Dirac 3 Distance Level PEQ Distance Level

Here is our User Manual for Dirac 2. Proofreading: Page 10 should say macOS, not iOS. Page 11 should say Dirac, not DIiac Page 13, thet insted of that. which speakers are active in thet speaker preset Mitch

This is certainly true in the XMC-1 where you cannot even access any distance settings for the Dirac preset

It is only an eq filter setting under the normal presets. Hence why I posted this on the first page. "So am I understanding this correctly: Dirac for the Emotiva will not set Distance, Level, or Size? It will only generate a EQ filter set?"

You select the size You can apply level trims
However, although the speaker preset has distance settings that you put in, these should only be active for PEQ or no equalisation. The distance settings should certainly not be implemented and hopefully Emotiva have it setup so that selecting Dirac equalisation will disregard these distances and use the measured and then impulse aligned delays from the Dirac filter creations.

We can only assume there is more below the Dirac setting.

Many users and even some enthusiasts have no way of knowing how to set their distances correctly, especially on subs. You cant just use physical distance. A lot of users don't know how to set levels properly either. Automatic room correction is supposed to remove a lot of the needed knowledge to manually setup an advanced audio system.

Based on the Monoprice manual, Dirac sets delays in milliseconds and levels. Dirac doesn’t set size.
