All bass in the center speaker

[Labbrat]

I have homecinema reciever that works great with all games except RB2.

For some reason I get all the bass sounds (drums and bass) from the center speaker and it sound horrific.

If I switch to 2.0 I can barely hear the voice and the rest of the sound is kinda fishy.

For ur information Im on a PS3 and always go digital when available.

Any ideas why its like this? Would like to enjoy the game with more or less only vocals coming from the center speaker, as it should be.

Played some more when I came home today and its worse then I remembered from work. The vocal is crappy as hell even in 5.1 and the center speaker is about to blow from the drums and bass. And no i don't have the boost checked.
As I said before if I skip 5.1 sound I cant hear the vocals at all (almost).

It's funny coz it works perfect with GH and other games and ofcoz all movies and the digital box.

Welcome to the RockBand Forums

Are you using HDMI for Audio?

Perhaps one of the Audiophiles will chime in.

Nah Im using an optical cable from the PS3 to the reciever.
The HDMI is connected between the PS3 and my projector.
