Of course ADA is supreme, but it's like having a Buggatti Veyron and you cannot take advantage of it.
First I need to thank Dan for the being so extremely precise and to RefTheater for the wonderful comparison as I have always been fascinated by Buggatti. To both of you, I couldn’t have said it better myself. Again, thank you.
But for those that have somehow misconstrued Trinnov as being too complex, I would like to simply take a moment to provide my two-cents having worked with the technology intimately for several years now and I am by no means as close to capable as some of our esteemed folks here on AVS.
To me, Trinnov is a piece of cake to set up with extremely favorable results. As I see it, setup takes place in two steps, three if you have some flexibility in moving speakers
The first step involves your systems speaker configuration. ADA provides both 2 and multi-channel presets for either ITU or SMPTE that include configurations and even a start-up target curve (modified SMPTE curve we created with Curt’s assistance). You select the preset that most closely matches your system and then save it into the first preset position. From here, you can customize your speaker setup should one of our presets not exactly match your speaker array. If you are doing active crossovers, then there is more to do and here I would definitely defer to Curt or a professional like Dan for advice and support.
Once you have your inputs and outputs setup along with the routing of signals, you proceed to take your first measurement from the primary listening position. Here the trick is all about aiming the microphone placed at ear level from the primary listening position. Taking the center mic element and the front mic element, you stand behind the mic and aim it at the center of the screen paying attention to see that the mic head appears level. After your first calibration (measurement sweep sending pink noise to all channels one at a time), take a look the center channel azimuth measurement to make certain you within 2-degrees (meaning your aim was true). If not, then re-aim the mic and repeat. Getting within 2-degrees should be a piece of cake by simply eye-balling.
Once you have a good fist measurement, the TEQ provides detailed information about where speakers are found in the room. This is unique to the technology- and is a key feature of acoustic image remapping. There are both the top-down and horizontal views where you can note the standard speaker placement (solid green-colored speaker) as well as the actual speaker positions (noted by two-colors).
You can now choose to physically re-align your speakers to conform better to the playback standard of choice, or you can simply allow the TEQ to perform it’s remapping of the acoustic space with the given speaker placement.
Then simply take all the measurements your heart desires. You can label each position so you have a reference of where the mic stood. In say a multi-seat theater, I would take measurements at each seat location as well as measurements high and low where no “head” will be situated in various parts of the theater just so we can get a sense of what is acoustically taking place in these locations. Each position can be individually weighted (relative scale where 1 is low, 0 is not used, and the higher you go, the more importance that position has in the calculation). For a preset when the theater is full, you might weight the money seat slightly higher than the others. I then suggest saving this same preset under additional presets (up to 29 presets capable). Like the measurement points, you can label each preset (theater full, 1st and 2nd row only, 1st row only, center money seats, etc.) where all that changes between these presets are the weighting for each measurement position.
I have personally setup theaters all around the world never leaving my desk in White Plains, NY. The results are massive and yes, there is still more one can do. As Dan notes, this is where having a professional do the installation really pays off huge dividends.
