Denon 3805 and LFE

[mtrycrafts]

Is that pre or post bass management? I was just analyzing the individual channels of War of the Worlds. 20min in(emerging Tripod scene) there is more bass in the mains then there is in the LFE channel, in fact the LFE channel hardly reaches below 20Hz when the mains hit peaks at 10Hz. I'd call that surprising. When you look at ID4 the LFE has almost no information stored on it in comparison to whats in the other channels as far as bass is concerned.

This would be post processing. All speakers large and a sub or two, monitoring the amp to the passive subs. The levels may not be loud much of the time but certainly able to see the meter on the amp constantly moving off the peg..

You could put a volt meter on the wires and see the voltages.

I was using Sound Forge to analyze the actual recorded information in the separate channels, and comparing the sub 100Hz region for the LFE, Left and Right channels. I was just surprised at the amount of bass recorded on the main channels(even the surrounds) in comparison to the LFE channel. It just seems the LFE channel is just to add more bass to what is in the other channels. So, IMHO, if the mains and/or surrounds speakers cannot reach as low as the sub(in most cases they can't) they should be set to small and crossed over appropriately, otherwise some bass information is being lost

I just checked the speaker level setup option to see if the sub's volume is the same or not with the amp's internal test tone - I did manual, and All Speakers Including the Sub is the same, All have 0.00db assigned next to them, is this normal, are they suppose to be at 0.00db?
I am still not sure what you mean by - (See if the sub's volume is the same or not with the amp's internal test tone (as opposed to the Avia)?
Thanks Bobby

Sorry I haven't responded sooner, been away for a few days.

What I meant was that the Denon can produce its own test tones from an internal noise generator. So instead of using the AVIA disc to generate noise for you to measure or assess that the sub level is too low, see if the Denon produced tones result in the same "low level". The speaker set up, leveles menu allows you to either let the Denon cycle through each speaker in turn, or you can manually select each speaker through which you want to have the noise produced. Then select the Sub and see how the level is.

TBH, to have all levels at 0 db sounds as though either you have done no level adjustments at all for your speakers, or there is a fault with the amp. I recommend a processor reset, you really do not have nothing to lose at this stage.

Yes, the Sub only has 2 RCA input, so the Cable is plugged into the Sub

How come you answered for george?
BTW,where is he?

In the test tones, where you can hear a hissing coming from each speaker, the Sub also responded as did all the other 5 speakers.
Yes, all the levels are at 0 db, but I haven't done any level adjustments on them, because I didn't know what to set them to, And I quess the previous owner must not of set them either.
Is there a certain db that each speaker should be set at? I Tried moving the Sub db up alot, and you could tell as you was moving it up in db's, but when you set it, I really couldn't tell that it help with music, movies, Ect.? Any thoughts? Thanks Bobby

The test tones generate pink noise and are used to calibrate the receiver so that each channel plays at roughly the same volume. You can do it by ear but it is far better to use an SPL meter. If you search the forums for 'calibration' you will get tons of information on the topic.

George's question has been answered, and the thread has been hijacked by
Bobby, that's probably why

Also Mtrycrafts and I went a bit off topic

cheers

OK, If you had the sub connected via the pre-amp outs on the 3805 then this proves they are working. How is your player connected to the 3805? Digital or analogue?

cheers

Sorry, I didn't mean to hijack this thread. For some reason I haven't gotton memberships yet, so I can't post? I Registered, but no luck so far.
Any, I am pretty sure everything is analogue (RCA Cables). Thanks for everyones help so far.

One other question, my Remote for the 3805 Freezes on me an alful lot, especially when I use the Off Button on the Remote, is this a common problem with this Remote, or is there a remedy? Thanks Everyone!

OK, What brand and model is your player?

Are you using the EXT-IN on the 3805? If so then the 3805 is doing absolutely no bass management, so your players bass management must be set up correctly. Also how many analogue audio connections between the player and 3805(EXT-IN) are connected(you'll need 6 for 5.1 surround over analogue)

And Why don't you use the Coax/Optical Digital connection because 90% of the functionality of the 3805 is not being used?

Don't press the big OFF button at the top of the remote, some of them have this glitch. Instead, put the remote in AMP mode and press the back-lit 'SOURCE OFF' button just above the AMP/TUNER button.

MACCA350, Thanks for helping me!

Ok, wait I may not understand what you mean by player (Can you clarify for me), I am new to this stuff, sorry.

Also, can you tell me what the difference is between analogue, and Coax/Optical Digital, and where can I get the Coax/Optical Digital?
I have only ever hooked equipment up with RCA, is it easy to hook everything up with Coax or Ditial, and get it setup right? Sorry for the dumb questions, I have alot to learn from you all. Thanks Bobby

Player = DVD/CD player, etc.

The digital connection allows for multi-channel transmission that include formats like Dolby Digital & DTS NOT SACD or DVD-Audio. You need to check your source (player) for which type to use: Coax or Optical. If it can use both, it doesn’t matter which you choose. You can get one wherever audio gear is sold.

If you can tell us how you have things hooked up that would help. If you’re only using the stereo analog connection, you won’t have use of all your speakers.
