General DTS question but specifically related to JP3 in this instance

[Roy]

Hope that subject header made some sense:)

I watched JP3 last night and noticed a very strange difference between the DD 5.1 track and the DTS track.

Before you ask, I didn't watch it twice but there is a good bit at the beginning that is useful for a comparison.

It's when the Universal logo appears and the water ripples with the "thoom" sound.

When I played the DTS track the "thoom" was very weak indeed, barely any bass at all, yet when I play the DD 5.1 track it was much deeper and resonant.

Now, I should say I don't own a sub but I have got my amp set up correctly to allow for that and the config wasn't changed between track changes, neither was the volume.

I just wondered if this was typical? I would have expected the opposite tbh, as DTS tends to be louder.

Any comments/insights?

For info my amp is a Denon 1801, player is a Panny RV60.

I too have noticed very different bass performance with this film between dd5.1 and dts.I do have a sub and had put it down to different bass management between the 2 formats.I believe it`s possible to mix the sound in various ways as far as the bass goes,directing it mainly to the .1 channel or putting it in the main left and right channels.It was the release of Jurassic Park(one) that highlighted this when contrary to all expectations the bass performance of DD 5.1 seemed more impressive than the dts but it was simply that the DD mix had more of the bass directed to the main channels on the basis that most people don`t have subs.

well that sounds daft way to do things!

whats the point in the amps having settings to redirect the .1 channel if its gonna be mixed on assumptions that people don't?

[Roy]

Hmm, it seems a bit odd I just admit, I had my amp configured to send all .1 output to the main speakers, surely that should overide the way the sound is mixed?

Oi! Careful what you say about Co(n)ventry :P
