thx loudness plus vs onkyo dynamic eq

[DonRSD]

after racking my brain i just decided to post
should i leave BOTH set to ON on my onkyo 806?

i notice that the thx loudness plus enhances the surround sound at lower levels

http://extranet.thx.com/technologies/loudness_plus.html

i just want to know if both should be on OR just one or the other?

i dont ever listen to my movies, videogames or music at reference, if that helps at all

This is the description of THX Loudness Plus from their website: "With THX Loudness Plus, home theater audiences can now experience the rich details and ambient sound in a surround mix at any volume level."

This is the description of Dynamic EQ from Audyssey's website: "As you turn the volume up and down, Audyssey's Dynamic EQ maintains consistent bass response, tonal balance and surround impression"

Before you run the Audyssey auto calibration program, it is a good idea to turn off the Night Mode, Dynamic Range Compression (DRC), and Dynamic Compression (D. Comp) in the receiver/processor as well as the player. In addition, if your receiver/processor has the THX Loudness Plus or Dolby Volume, you should turn them off as these may possibly have an adverse effect on Audyssey Dynamic EQ and Dynamic Volume.

After calibration, it is a good idea for most people to turn the THX Loudness Plus, Dolby Volume, and Audyssey Dynamic Volume off. Turn Audyssey and Dynamic Eq on.

Don,

I believe you have babies in your house. It may not be a bad idea to turn the Audyssey Dynamic Volume on and set it to Day, Evening, or Midnight mode to cut back on dynamic range in order not to disturb the little ones.

i turned OFF thx loudness plus & dolby volume.
i do have audyssey dynamic volume ON

my 806 doesnt have dynamic volume
it only has dynamic volume for dolby sources, so if i watch a dts hd movie i cant control the volume which sucks.

im really looking into getting sarge sc-27 in the trading forum.......any thoughts?

I am not sure I fully understand your post. Audyssey Dynamic Volume is different than DRC option. DRC is only available for Dolby sources. Audyssey Dynamic Volume should be available for all sources.

I've actually been using THX's Loudness Plus this whole time without the Dynamic EQ (despite running audyssey and everything). So now when I click to use Dynamic EQ and shut off the "Preserve THX Settings" option, what exactly is that turning off? I am still using THX Select2 Cinema (with Re-Eq Off) but what exactly gets shut off?

Audyssey Dynamic Equalization and THX Loudness Plus pretty much do the same thing. According to Audysey, their Dynamic Eq is more advanced.

I really do not know the exact answer to your question. My receiver does not have THX and I am not familiar with your Onkyo receiver. It may be a good idea to consult the manual and/or send an email to Onkyo or Audyssey.

The following is from a post by Chris Kyriakakis of Audyssey

Audyssey MultEQ creates room correction filters to two specific target curves. One is the Audyssey Reference curve that has a slight roll off in the high frequencies above 10 kHz that has to do with the translation required from a large movie theater to a smaller home listening room. The other is Flat that has no roll off. Some AVR makers decide to give the user a manual choice and others, like Onkyo, make the switch automatically.

Re-EQ is not an Onkyo function, it is part of THX. We recommend using the Flat room correction curve so that the intent of THX Re-EQ is preserved. Onkyo allows you to switch Re-EQ on and off separately from the other THX functions and so you could listen to Audyssey Flat if you turn off Re-EQ.

There is no interaction between the Re-EQ button and Audyssey. If you are in THX mode then you are listening to Audyssey Flat regardless of whether you have Re-EQ engaged. Of course, if you do have it engaged it applies a high frequency adjustment that takes you away from Flat. I recommend using Re-EQ with Audyssey Flat for movie listening.

There is no way to have Audyssey Flat in Onkyo products without having the THX mode engaged.

In Onkyo receivers with THX, if you turn on Re-EQ and you are not in THX mode, then you will be using the Audyssey Reference curve plus Re-EQ.

DonRSD & ClaytonMG, I hope you both have THX-spec'd speakers.

I'm assuming that Onkyo uses the flat set up without the high frequency roll off.

So if I am reading this correctly, I should use Dynamic EQ with THX's Re-EQ enabled?

I'm not sure about this. My understanding is that the Audyssey MultEQ calibration completely ignores AVR settings.

A quote from Chris Kyriakakis on the Audyssey thread at AVS Forum (post #10516):

" ... any settings you make prior to running the calibration are completely ignored when you run the calibration. So, if you want to make a change it will have to be after the calibration is completed."


Another one (post #2940):

During calibration it completely ignores the internal settings of the receiver, so you will end up with the same results.

Are the setting you cited exempt from this general rule?

I agree. I guess someting got lost in translation. I get bombarded with private messages and questions. In my haste to answer the question, part of the answer got lost and went into a black hole.

Check https://forum.blu-ray.com/audio-theo...hnologies.html thread under How to Run MultEq.

This is what I meant to say:

1. Before you run Audyssey auto calibration program, it is not necessary to turn off Dynamic EQ, Dynamic Volume, or any other options. All internal settings are ignored when the calibration is running, including the volume, level trims, delays, and speaker settings. They are set after you are finished and saved the results of the auto calibration program
2. After calibration, if you plan to use Dynamic EQ and Dynamic volume, it is a good idea to turn off the Night Mode, Dynamic Range Compression (DRC), and Dynamic Compression (D. Comp) in the receiver/processor as well as the player. In addition, if your receiver/processor has the THX Loudness Plus or Dolby Volume, you should turn them off as these may possibly have an adverse effect on Audyssey Dynamic EQ and Dynamic Volume.

Thanks! That makes sense.
