DEQX Beginner seeking advice


Hello DEQX Users,

I have a demo PreMate on loan for 2 weeks. That is not much time, given the complexity of setup. For now, I am skipping speaker calibration and trying to get room EQ running well. It is the bass in my sealed basement room that's the problem most in need.

1. Is there an online tutorial on this?  I looked at Nyal Mellor's YouTube entry, but I'm looking for something a little more detailed (but less than the manual).

2. Is it true that DEQX room EQ (unlike the TacT 2.2X I own) is applied to both channels, and can't be used to equalize each channel independently?

3. Is it also true that (unlike the TacT), a DEQX main/sub configuration does not automatically set time delays and levels relative to the mains? If so, how do most users accomplish this?

I will appreciate for any tips/help. At first impression, the DEQX DAC and xover sound considerably cleaner than the old TacT, but the complexity of setup is rather daunting.

Thanks!
Mike

P.S. I trust that starting a new thread is the right thing here, rather than hijacking the long, interesting, existing one.

make sure you guys read this long thread "Is DEQX a game changer" 

https://forum.audiogon.com/discussions/is-deqx-a-game-changer

we've discussed many of the questions you are asking in this thread.....
thanks.
Thanks for chiming in bombaywalla. I actually read almost the entire ""Is DEQX a game changer" thread before posting. It took me a few days to get through it! I didn't see any of my specific questions/comments addressed. Of course, it's possible that I missed something, but I really tried seeking out the info I was looking for prior to posting. 
Blang11, welcome to Audiogon! As you can see in my system description thread I am using an HDP-5 in my system, which serves as my line stage preamp in addition to providing its signal processing functions. However my system does not include subwoofers or any form of biamping, so I can’t comment knowledgeably on some of your questions. But I’ll give them a shot:

1)I’m not familiar with what Devialet has done in that regard, but I’d imagine it would probably be impractical for DEQX to either do that sort of thing themselves, or to provide enough different speaker manufacturers with their equipment for the measurements to be comprehensive enough to be worthwhile.

2)As you may have seen in the thread Bombaywalla referenced I performed my measurements with the speakers moved to the center of my living room, with large acoustically absorbent panels placed against nearby walls and other reflective surfaces. But the one or two or three second tone bursts that are used for each speaker measurement are typically set to automatically repeat numerous times, which under most circumstances apparently allows the software to pretty much filter out and ignore extraneous outdoor noises.

3 & 4)Many analog volume controls operate similarly, of course, with respect to the resolution of the adjustment becoming coarser at low settings. The gain structure of my system is such that for my critical sources (LP and CD) I use the control in the upper half of its range, where I find the resolution to be satisfactory.

Ideally I too would certainly prefer a numeric readout of the setting, that would facilitate precisely returning to a given setting, but I can live without it. And although it is less convenient, it is still possible to do that using the up/down buttons on the remote, by going a given number of steps above or below a setting at which the light changes color.

Also, as you have most likely seen, the HDP-5 and also the Premate+ provide a volume slider on the touchscreen in addition to the indicator light that is provided on the earlier models. That is of course still less than ideal compared to a numeric readout, but I find it to be a marginally useful feature.

5 & 6)Can’t comment knowledgeably.

7)I don’t do any critical listening off-axis. But many users including me leave profile 0 (the others being numbered 1, 2, and 3) in its as-delivered bypass configuration, so that the speaker and room corrections can be disabled with one press of a button on the remote.

8&9)Can’t comment knowledgeably.

10)I didn’t use the DEQXpert service, but I am somewhat familiar with the experience of one of the members here who posted extensively in the "game-changer" thread and did use the service, and who has a room that is particularly challenging from an acoustic standpoint. The session involved a few hours, with results that he found to be satisfactory at the time. A few months later he purchased another session, which also lasted a few hours, and resulted in some further improvement.

11)I’m not 100% certain, but I believe the answer is "yes," especially given that one pays for the service. Also, I believe that Nyal Mellor can provide a comparable service. I purchased my HDP-5 from him, and yes, he was wonderful to deal with.

Good luck. Regards,
-- Al

Re: #7

In my previous apartment, my most comfortable seating was also off to the side a bit in what could hardly be described as a sweet spot. I never got around to it (and have now moved into a much better situation: most comfy seating in sweet spot and room for my speakers to get away from the walls), but I'd thought about making one of the profiles specific to that less than ideal seating spot. On that profile, you could just place the mic at that location in the room. If you'd be moving around in the room, do multiple mic measurements (from spots in areas you'd likely find yourself) and get the best possible room correction from those measurements. 
Roscoe, congratulations on the new digs, and on the improved acoustical situation!  And thanks for posting the links to the John Darko reviews in the "game changer" thread.

Best regards,
