Hi Keng,
Dynamic Volume has a very simple mission: to prevent things from getting too loud. In fact, for music it can be very useful because the levels for each song are so different. If you don't want to constantly keep changing the volume control between songs then you should use Dynamic Volume.

Hi Chris:
So in this case, for music (stereo) it will be better to have Dynamic Volume off? In other words, it will sound more "true" then with Dynamic Volume at Light? Assuming listening at decent volume at daytime. Appreciate the feedback. Thanks!~Keng

At home, the Center speaker is often in compromised locations (on the floor, in cabinets) and is not pointing to the listener. Getting it to point to your ears is a good start. Running the MultEQ calibration is a good next step.

The amount of compression changes continuously with content in Dynamic Volume. That's one of the innovations we brought to this. Fixed compressors can cause artifacts. Dynamic Volume uses a look ahead buffer to estimate the needed changes and then applies them to the content before it is played.

I really like the dynamic volume feature working together with dynamic eq. For movies i always set it on light to hear the widest dynamic range and crips clear dialogue just like in the movie theater.

I got some questions:

how come in movie theather's the dialogue is crisp and clear and at home not ( without using dyn eq dyn vol ) even if you have good speakers?

If i have dynamic volume engaged on light, how much is the compression for gun shots and explosions?

Dynamic EQ has no effect on dynamic range. It is there to make frequency response adjustments so that the variations in human hearing at lower volumes are compensated and the octave-to-octave balance of the content is preserved when you listen at levels below film reference. It also adjusts the surround levels so that the reference surround impression is maintained at lower volumes.

If you want to avoid changing the volume between dialog and explosions then you need to engage Dynamic Volume. It uses dialog level as a reference and makes sure that nothing gets too loud or too soft around that level. The three presets simply indicate how wide a variation from softest to loudest will be allowed around the reference dialog setting you choose. The reason numbers are not given is that the compensation depends on the content and the master volume setting. Unlike past methods that set a simple dynamic range compressor with a fixed reaction time and compression range, Dynamic Volume uses a look-ahead buffer to identify the timing of the level changes in each channel and then applies dynamic range compression with the appropriate time constant to avoid the pumping artifacts that past methods have suffered from. It took a very long time and many hours of observing and recording listeners in our labs to come up with this model of “reverse engineering” human reaction to changes in volume level.

Does Dynamic EQ also change the dynamic range at all? Meaning if you set the volume on a receiver with only Dynamic EQ on to a comfortable listening level, will you have to constantly adjust the volume to hear people speak / turn down the volume for explosions? And can we get more detailed information about the different settings of Dynamic Volume – “Heavy” compared to “Light” to Dynamic Volume being turned off corresponds to about what level of dynamic range compression? For those who like details, saying “heavy” is akin to saying “large speakers” – unless you know what it means it means nothing or worse it means you will use the settings incorrectly.
