ADA steps are transparent per se. markus has even posted some evidence that they are.

If people want to believe an additional ADA step does matter, or to take no view on it at all, that is fine....

Yeah - my subs (Submersive) only have XLR input but I use the XLR-RCA converter that they supply with the sub. (No XLRs on my Denon 5200). When I had the Onkyo processor that had XLR so I used it for...

Might as well use just one point, single measurement, which has already been done.



Absolutely. And I'd add 'ease of use' too.

True enough - but there are also wires to construct and the permutations of dip switches and so on seem more complicated, with additional complications for gain matching. And if one has a mixture of...

I have found that using unbalanced cables throughout has made life much simpler, with no downside (given that my cable runs are short and tidy). With the 88A, using balanced adds to the complexity...

Yes - he had a HTPC in the system. Something in it had apparently failed or gone wrong in some way and was the cause of the noise. Removing the HTPC temporarily has solved the issue. He is currently...

Scott, I think you need to develop more understanding of how this all works. To calibrate properly one needs to use all 9 mic positions sequentially so that Dirac can build a picture of the room,...

What makes that UPS suitable for power amps? I know nothing about UPS - this one has a VA of 700 and Watts of 400. Is that enough for 4 power amps - the 300 watt (into 4ohms) XPA-3, the 150 watt (8...

That's OK. AFAIC the 88A is transparent. Nobody has posted any evidence which shows that it isn't. If you have some, please post it. Otherwise you are saying I am just 'believing' that the 88A is...

Are you deliberately misinterpreting? The point with the measurements I posted is that the mic never moved.

How does that help with the variable height of the mic positions? The fact you can't come up with a way to do this shows that, contrary to your assertions, it is far from easy.

No if I say so - if everyone says so. Move the mic between measurements, the graphs will be different.

How do they ensure it is in the same spot every time? I guess they could suspend a golf ball on string from the ceiling so that it is where the tip of the mic is. And then repeat it for the other 8...

They do? People are all the time replicating mic positions when they use REW? That is news to me, and I've been a REW (and OmniMic) user for ages now.

Thanks Roger. I may add a rackmount UPS just for the 88A. For just the 88A, a relatively inexpensive one will do. I imagine almost any would power the 88A for ages. I don't think there's anything...

Not sure what you mean here. I have no doubt about the transparency of the 88A. The additional ADA conversion is irrelevant to anything audible IMO.



Just reiterating my position. If I believe...

Thanks for the hat tip but most of the Sub Distance Tweak Guide is the work of other people, as acknowledge in the guide. What I did was bring it together all into one place. Glad you found it useful!
