Besides the
Audyssey manual which is quite detailed, I am going to update this thread with important steps that need to be done when setting up Audyssey measurements and settings, to ensure that the resulted output sound will be as good as possible with this software:
-1) Measure correctly, in all 6 positions accepted by the MultEQ, the red ones from the image below, because more measurements means more data that will be used to calculate the equalization filters. With MultEQ-X the maximum number of measurements supported is 32, but unfortunately this version is not supported by the CINEMA 70s, so we'll need to rely on only 6 measuring points.
Bad vs. good microphone positioning, straight to the ceiling
For MultEQ measurements you can only use the 6 red measurement points
-2) Purchase and use the MultEQ app from AppStore/Play, so you can visualize and later edit per your own convenience the measurement results. After everything has been properly done, just push the Audyssey results straight to the AVR from your cellphone. Worth mentioning that there's a no. of max. two Audyssey listening positions that can be measured: one for Speakers Preset #1 and another one for Speakers Preset #2. In my case I've used them for: Couch and Pouf (bean bag in the middle of the Livingroom). Each listening position can have more measurement/settings (one with less or more bass, another one with less or more trebles etc.).
Both Apple Appstore and Google Play store have the MultEQ Editor for Denon/Marantz receivers
-3) Properly analyze measurement results for each speaker and do again the measurements if you spotted any inaccuracies there.
- 4) If you have full range speakers then MultEQ will turn the crossover off and mark them as Full Range, but if you have a good subwoofer then I suggest to change this setting to 40 Hz instead, so the subbass to move gently from the front speakers to the subwoofer. This will lower power consumption on your AVR, but will also increase sound quality and minimize unwanted subbass reflections that now will come only from sub instead of sub + two frontal speakers.
Crossover settings recommended by Audyssey can later be altered. In my case I changed the Full Range for Front speakers to 40 Hz, like above
If the Distance or Level are not very accurate it's OK, you can later adjust these settings per your liking
Do not expect wonders from MultEQ, though my small JBL Control 23-1 speakers acting as front Dolby Atmos have been EQ'ed pretty well above 200Hz
I really like how my SVS SB-3000 subwoofer has been EQ'ed, hats off here Audyssey!
Audyssey is for watching movies, so trebles roll-off seems to be a must, though it can be later adjusted to get a flat response
My JBL Control 28-1 surround speakers are having their crossover at around 2kHz, which can be seen from the above green measurements, hence I'll turn on the Midrange Compensation for these speakers, as per Audyssey recommendations (red) to not emphasize the midrange around 2kHz
Given the green result from the above images, I decided to check the Midrange Compensation for my JBL speakers
You can later adjust the freq. response per your liking by adding multiple inflection points, including for the trebles.
Green is what Audyssey recommends based on its measurements, while red is trebles frequencies modified by me temporarily.
The desired frequency response (without the EQ coming from the measurement corrections) recommended by the Audyssey
If trebles roll-off is an issue (although it can be set to Flat earlier) then drag the curtain to a lower frequency, shadowing this way the trebles to be rolled-off
Dynamic EQ is strongly recommended because it acts as a loudness. When volume is increased then this loudness will get automatically notched down or canceled
MultEQ set to Flat will disable trebles roll-off, while setting it to Reference will enable trebles roll-off
Dynamic EQ acts as a loudness, while the Offset setting sets the level of this loudness effect
The default crossovers can be adjusted later as well
Of course, performing additional REW measurements with ca calibrated microphone might help in double checking the Audyssey measurements and later to manually adjust the settings to perfectly match your room acoustics and your preferred audio curve.
However, after I was properly performing the Audyssey measurements and setup I am now able to enjoy my daily listening to both movies and music from TV/BD/SACD discs. It's all about setting Audyssey properly, although room treatment plays a huge role in this as well. Dolby Atmos is absolutely terrific when playing supported movies, while Dolby DTS-HD is incredible when listening to large orchestras.
