Genelec 8331 : Trinnov VS GLM Genelec [AUTO] page3

Casa-T SPDIF>AES
That cable is AES->Coax, whereas with the PO100 Pro, you would need Coax->AES.

The USB->AES converters I linked above have the advantage that you can use regular AES XLR cables without worrying about converter cables.

I didn't understand how to connect the speakers together if I switch to digital Is there a cable?
Here's the basic layout:
Blank diagram (28) (1).png

That diagram assumes the 9320A GLM controller is used, which has AES output built-in.

With the basic GLM controller, you'd have:

PC->USB->GLM->RJ45->Left 8331A->RJ45->Right 8331A
and
PC->USB->DDC->AES->Left 8331A->AES->Right 8331A

You really should EQ them with GLM, there's a massive 20dB boost from the corner at ~48Hz and ~120Hz. If you can see any wiggles in a 380dB Y-axis graph there's really a huge problem

I just received the GLM, I'm going to equalize otherwise I don't understand your message, what a huge problem?

It's all in my post, anyway make sure you add some low end after the automatic calibration using Sound Character Profiler, a +3dB boost below 100-200Hz is a good start

Excuse me, I'm French, I sometimes had trouble understanding English


Thanks for the advice
 
I'm moving forward with the treatment I have already placed the bass strap 2m high then the 3 plates with distance from the wall I'm going to move on to the measurements to check the intakes (RT) I still have a lot of work to do: the cloud on the ceiling, the area behind me





 
Connecting through XLR (on the speaker) to TRS (on an audio interface) can be achieved with an XLR to TRS cable, and I think will maintain fidelity without needing a second stage of DAC conversion since the connectors are just different versions of the same thing.

precisely, I am advised to be in AES and not to put XLR to an interface

Ah ok I see now - the Genelecs have AES/EBU inputs. That's very cool! For the absolute best fidelity, AES is definitely the way to go since your speakers support it.

Also, XLR is just a connection type. AES/EBU cables often use XLR connections since they are balanced. So there are AES XLR cables and Analog XLR cables. It's nice and confusing. Kind of like how Thunderbolt 3 and 4 cables have USB-C connections, but use a completely different protocol for data transfer than regular usb-c cables.

if you use an audio interface meant for music production, the interface will need to have AES outputs. I like the cost efficiency of staticV3's suggestions. I had a little trouble understanding but I think I got it after a bit haha.
 
next step the ceiling with Basotect 10cm, small diagramI


free album maker online

Basotect 10cm with air gap behind the desk,



will extend the treatment to enlarge the treated surfaces, still Basotect 10cm, 7cm and 5cm depending on the constraints

don't bother with basotect, it's just a fancy name for foam and it will change nothing under the desk or really anywhere outside of the first reflection points. If you used it in the corner you're stopping yourself from any real improvement, as it's not a bass trap. It's hard to see the spectrogram scale and details, or any graph you posted to be honest, but it seems like you have a massive 2 seconds resonance at 50Hz, this is something that should be addressed in the first place, not foam behind the speakers where they don't radiate in the range which this foam absorb anyway.

If you have the luxury of time, encasing sheets of Roxul (made for complete sound absorption) with 2x4s and covering with a bed sheet of choice for artistry can provide Excellent bass traps and early reflection killers. But this requires careful consideration if putting on a ceiling.

I only have experience with using this when I was on an extreme budget - but it worked (I did the ceiling ones without 2x4s).

ran blind tests in an audio forum I belonged to for an album I mixed in that room and the results came back strongly that the original mixes (when level matched) were better than the final masters. I attribute this to room treatment because the speakers were low-middle of the road (Alesis M1 Active Mk2). But what I got in the end was a clean enough sound that I could make pretty accurate mix decisions, especially as I referenced against headphones and other sound sources.

This my subjective experience as I don't have the tools to measure this. I'd just say that it's worth looking into as there is much snake oil in the acoustic treatment space ... just like the audiophile space :)

to tell the truth, I also count on the work of the GLM of genelec to help me with the bass
 
I am moving forward in the treatment,

I have revised the surfaces to be treated upwards

I must be at 60% of the way forward

actuellement en test avec un Trinnov afin de comparer en mode auto avec le GLM de Genelec contre mesure avec REW pour ne pas me laisser trahir par la subjectivité

Looks like you're going in the right direction and you already must have a pretty sweet sounding setup! Do you plan to add one or more subwoofers?
