No, the ADA mics have a different configuration, without the LED. For Trinnov units, the mics have an internal battery. The LED was added to version 8 mics along with an internal preamp. The LED both marks the front and indicates the battery is good. In the case of the Reference, there is no need for a battery, as both the preamp and mic power are in the Reference, so no LED.
Trinnov Reported Levels. The reported levels are relative levels for all speakers on a scales from - to +20dB (like the volume control). Trinnnov measurement indicates you turned up your sub 10dB (from -5 to +4, including "0dB = 10dB of gain change). The goal is to have the sub level be near the level of the speakers. This is because if there are big differences between speakers, the required level correction to make them all equal eats up the system's headroom by the...
The reason behind this option is that many people buy speakers for their particular voicing. The value is that the correction keeps the L/R voicing, essentially a custom target curve.Trinnov corrects for room issues in L/R, and modifies the response of Center and Surrounds to match, within the limits of correction. The "matching to L/R is three steps:(1) Trinnov measures all speakers, (2), then smooths L/R response to their overall curve, and (3) correction is applied...
Hi All There are several 3D algorithms on the market that have real benefits to users- the discussion above indicates that Yamaha may have such a system and that it performs well. There are others that add wide channels, etc as a static choice (meaning that it's a fixed system). These implementations differ greatly from Trinnov Remapping, as Remapping is an active, automated process that takes place in your listening environment based on your physical arrangement. ...
If I understand your goal, you would like a preset for (1) full range speakers only and (2) speakers with sub, xover at 80 hz. Certainly, this can be done using two presets.For (1), full range speakers only- calibrate all speakers without the sub present. Playback with Trinnov engaged with this preset will be "full range, w/o sub" regardless if the sub is then reconnected.For (2), speakers with sub, xover at 80 hz This takes a bit more creativity, as you will need to...
Assuming all three speakers are in front, then of course you would loose the rear info, but you would in any case, with or without Trinnov engaged. I suggest you read the User Notes as it related to Quad.
Levels are relative: you have great results with only a 2dB spread. It is not necessary to be in a specific SPL range, only to do your best to have relative levels as close as possible. One wants to avoid having a big difference that usually comes from mis-matched speaker inefficiencies or a sub level that hasn't been matched to the speakers. Some level differences can't be avoided, such as having speakers situated from the listener at widely varying distances, like...
USB music playback- the R972 will play music from the USB input- but, for reasons not know to me, Trinnov correction is OFF/bypassed on the USB input. The ideal way to play "computer audio" is to connect from a SPDIF out on the computer to a digital in on the R972. There are several USB > SPDIF converters that are quite good for this purpose.
The "trust but verify" measurements happen regularly for those with the means, desire or need to make it happen. I've participated many times in independent verification measurement sessions, with motion picture studio clients as well as in several high end home theaters. The same can be done for the R972. R972 users are unique, because R972s are used anywhere from bedrooms, family rooms to custom designed home theaters that include acoustical treatments. It's a...
Wiki defines this well: " The group delay is a measure of the slope of the phase response at any given frequency."http://en.wikipedia.org/wiki/Group_delay_and_phase_delay Worth exploring if one wants a better understanding of the role time plays.Same measurement information, given in different ways. Of the two, phase is easier to relate to to see speaker/ room behaviors. Group Delay is often used as a benchmark for defining when we'll hear changes (relative to...
