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.

Drewan77, I would like to thank you !

I have been playing with my DEQX Express II for a while and I thought I knew most of the nuts and bolts, but in your post above on subwoofer time alignment, you offered a major league trick I didn't know and even ever think of: measuring the actual delay between mains and subwoofers at the listening chair : really smart !

So far, I have only used the DEQX utility to calulate the required delay based on the distance between the subs and the mains, which provided what I thought, a good result. When I modified those values with the actual measured values using your process, wow, much better, without any doubt! The result is a convincing demonstration of the benefits of a well  "time aligned" speaker system and while I will not describe those benefits because you all know them (!), I can't resist to say that the improved "soundstage"/"imaging" was what striked me the most !  

So again, thanks Andrew for sharing your knowledge with us and if Alan (Langford) is reading this... Alan, this is something that should be added in the DEQX user manual !

Regards,
Denis 
Thanks Denis, you're welcome & glad you're enjoying your system.

(I guess I must be telepathetic (!) or something as I rarely look into this site but just glanced at it within 30 mins of you posting!
Hello Mike. I was the OP on a lengthy DEOX thread,perhaps the one you've seen. Countless gents graciously contributed to it. I would suggest you browse the thread and send questions to those who addressed your interests. Good luck. Pete
The result is a convincing demonstration of the benefits of a well "time aligned" speaker system and while
one correction (major, in fact. :-) ) - once you did what drewan77 suggested you’ve corrected your speaker system become more time-COHERENT (not just simply time-aligned). Time-aligning is aligning the acoustical centers of the drivers while time-coherent means making an effort to ensure that the sound waves from each driver arrive at your ear at the same time. While you might not have achieved full time-coherency (you probably need to tweak DEQX a bit more) you’ve certain made a step in that direction. In time-alignment there is little guarantee that the sound from each driver will arrive at the same time at your ear but the action of time-aligning is a requirement for time-coherency.
