This thread is to post your questions about TacT.
Hopefully an Emotiva representative can answer or get answers to our questions before the XMC launches.
Here is my first one.
I have read that TacT only needs one measuring point to do its magic while competing products use several.
Since the common conception is that more is better, why in this case would less be more?

Will Tact let you control and measure 2 Subs as Audyssey XT 32 does so well?

If this is a fair place for "newbie" questions. For measuring response/room, does TacT do sweeps (pings, etc) similar to Audyssey?

Good thread to start hopefully Keith from Emotiva will jump in. That way everyone can get a jump on the release of the XMC-1 and be fairly knowledgeable in how TacT will work with the XMC-1.

I would like to know how well it will work for stereo 2.0/2.1/2.2 setups and if it can support setups for different modes like 5.1 or 7.1 and still have a different setup for 2.x
Also can it support setups for say 2 different rooms...i might have a fully bal setup in one room but rca in another room but just use the triggers to select one or the other amps...gear is all in one room

It looked pretty plain to me (wherever I saw the pic) certainly nothing like the Trinnov mic with it's multiple capsules.

So I hope they don't abandon their roots, or change things in favor of Home theater. Djoel |

I'm curious to better understand sub diversity too. I thought it was something like "handling 2 unique subwoofers, or handling 2 subs separately"......... but a google search yielded little info.

I would definitely be curious to know how, if any, the tact computations change when playing stereo vs multi channel.
I guess I didn't know whether or not it effectively measures and computes corrections for each channel or really wants to do it for all channels.
I am 80/20 music/video, but am really looking forward to Tact for my stereo music. I've always wanted to try it.

Per Dr. Boz..."the man" himself...his data shows that measuring mulitple locations is correlated perfectly to the data coming from 1 measure. So, 1 is all that is needed and more is just more data to have to collate/compute. He indicated with a grin that those marketing options touting the advantages of multiple measurements are basically touting marketing hype and not the science of sound (my words paraphrasing his...so not his exact words).

Tact will determine if there is a null created by one of the subs. It will then attempt to use the output of a second sub to correct for that null. This works because nulls are often caused by a sub's location in the room. If you have a second sub in a different location, it may not be affected by the null and can quite possibly correct the null in the first sub by increasing the output in that particular frequency. Tact calls it Sub Diversity and was explained by Dr.Boz at Emofest. It can be switched off BTW.

I'm familiar with SFM as explained by Dr. Toole. |

TACT really has my interest in the 2 channel realm. Yet I'm heading towards a XSP-1 based pre. Does anyone think Emotiva eventually may be headed in the direction of offering a 2.2 based outboard TACT implementation that could be leveraged through the woderful external processer loop that the XSP-1 offers? Or is this just not possible due to how TACT works.

Mark Is there any detailed information why only one single measurement would be enough? Most other approaches use multiple measurements. Here's an interesting link from Dirac: www.dirac.se/media/12044/on_room_correction.pdf |

Mark I find the remarks by Boz to be interesting. Maybe taking just one measurement with TacT is fine but maybe other RC systems like Audyssey are best suited taking multiple measurements. I have to be honest and say I'm not a fan of someone that slams other companies as Boz is with RC systems that use multiple measurements. I have read a number of posts from those that spent big money on the TacT TCS Mk II prepro and did not get any service when there were issues with them. I can contact Audyssey and get advice fairly quickly. Owners of the Tact TCS Mk II can not so one should be careful when slamming your competitors products IMO. Bill |

I'm no audio engineer, but just in my feeble mind using logic, it's impossible to optimize the audio for multiple seating positions. The response of the room changes depending on your location in the room. You can take multiple measurements and maybe end up with the best compromise between all of those seating positions, but it will never be fully optimized for any one seat. I believe that's why Boz says its just a marketing ploy basically. By measuring multiple positions you are only adding data to the mix that will ultimately degrade the optimum response from the main seating position, so what's the point? Maybe someone wiser and smarter can correct me. Just figured I'd toss that out there.
