Any AV geeks on here?

[Supragal]

Well, I'm a fan of THX, but not enough to have gone with a THX bluray player. But the AVR and Speakers are all THX and therefore it kinda makes sense to me to use it to set up (pretty sure they can't brand things THX unless it is certified). However, effectively all the settings do is set the crossover points, which I don't mind changing manually if it resolves the issue. I don't think it's anything anywhere near that range that is causing a problem - most of the bass sounds brilliant, it's just the really low stuff that gives me the issue.

 

Yes it was definitely on When it's powered the light is red, when it detects a signal the light goes green. So in normal use it is green, with Audyssey it stays red.

 

Yes the settings on the sub are set to Phase 0 and cut off frequency THX (which is full) either way, when using direct in, those settings are bypassed. They only come in when it's connected via boundary gain. Unless I've completely misunderstood it entirely!

 

For the record, I have tried connecting it using boundary gain, and adjusting those seems to make no difference either. Same for the volume on the sub (which is the round dial on the top at the front)

Are you able to save the settings to a flash pen or other? Just thinking that it may be worthwhile going for the bog standard setup without any THX settings or anything. See how it sounds completely flat. If it sounds OK-ish, I'm guessing there would need to be a substantial difference given your description, then just change one thing at a time to see what's happening. If it's still missing mid level bass then I would imagine it being easier to pinpoint.

 

Are you checking the audio with music? I always find it much easier to get settings to my liking using music. Additionally there should be some free videos with various Hz ref outputs to let you hear what you are lacking the most.

Well it pretty much is bog standard - you have to set the crossover points to something.

 

Also to be clear, it's not midrange bass that is a problem, it's crazy low bass AND another issue where somewhere in the general midrange it sounds flat.

 

However, I have just been through all the settings and I have left the equalizer stuff "off", I thought I had set it up but now remember that my mate was here so I left it for another day, so I reckon that is the key, however I need to find a way of testing all frequencies to tell me where the issues are, the free software sounds good but the ones I found need special soundcards etc so it had put me off. I'm sure that will get me around the midrange problem, but not convinced about the bass.

 

Anyway, settings:

Sorry if this is teaching you how to suck eggs but this might be helpful, it's fairly brief too and doesn't go into TOO much depth

Your right sorry, my mistake the AVR is THX certified I had it confused with another model.

 

For speaker type "Normal" can this be changed to small?

 

Low frequency information below 120Hz is, for the most part, non-directional, meaning that even if the info is “crossing over” from a surround channel, you won’t know it. The effect will still sound like its coming from the surround, thanks to the principles of psycho-acoustics. If you are concerned with changing the crossover point for the subwoofer start at 100Hz then change to 120Hz and see if that helps.

 

Also, have you done a system reset as Scott suggested as it might help the AVR pick up the Sub when running Audyssey.

Might be worth banging your room dimensions into this calculator to see which frequencies the room will naturally enhance. If you can route your PC through your audio setup with all the EQstuff set to flat then you can play each predicted resonant mode and see which ones boom.

Very nice setup, first glance at you're dog he looks like his paw is over his head covering his ear!

Are the three speakers on the wall full range? Are they creating a massive bass speaker being attached to the wall, can you try with them not on their speaker hooks and not touching the wall?

Have you switched off the sub and seen what things sound like then? Stick the sub on a pillow. I'm just looking at the unobvious as the settings look good.

System was reset originally.

 

No, that setting is just for bi-wired or normal. The "small/large" etc settings are in the "2.2" menu screen where you set the crossover points - i.e. you set a number OR set them to "large" for full range. (May try to get another pic to show what I mean, as it's not easy to explain unless you've seen it!)

 

I'm not understanding the theory behind setting the sub to 120hz, how does adding to it's range help? I thought you could localise it above 80hz?

Will have a look at this, cheers!

Na, that's just his big massive head

 

No, they're set to 80hz cutoff so should be OK. I think at the beginning I tried having the sub off, however it's a valid troubleshooting step. I think I need to get hold of a prometheus BRD and work through a list of steps, in a logical order instead of a bit at a time, which I suppose is what I have been doing. I am confident it is the sub only producing the boom, but never say never!!
