I'd sure hate to get rid of my Denon AVR 5800 for one small issue (well, I suppose there are some major benefits with new units, like more decoding modes and HDMI switching), but...


I seem to get no signal out of the LFE output (Effect/SB), either the left or the right. I run the speaker test and get silence. If I drive my subwoofer (Definitive powered unit) from another channel like center or front, the sub thunders away nicely. But I really prefer to drive the sub via the LFE channel. I am telling the AVR in setup that there is a subwoofer connected.


Are there any sneaky settings I could have screwed up or is it likely the LFE circuitry in the Denon is fried?


Any thoughts?


Thanks!

Isn't the 5800 just a 5.1 receiver. You should get the redirecter bass from the surround channels - not effect/surround back. Can't remember what options the 5800 has for surround back if any. If it has a 7.1 input you'd have to use an anlog 7.1 source. It may not be able to do bass management on the 7.1 input.

I am taking a stab in the dark here, but are you sure you are plugging your Sub into the LFE out and not the Pre amp's Subwoofer connection?

There is only one output. It's labeled SW and not LFE. Sounds like he has it connected properly because he gets redirected sound from fronts and center.

I'm going out on a limb here ... but do you have the subwoofer set to On or Yes in the receiver's configuration, and all speakers set to SMALL? If they're all set to large, it won't redirect squat to the subwoofer - the only thing that will play is the LFE track from a Dolby Digital/DTS soundtrack.

Hai,


The 5800 (with or without update ?) is a 7.1 with all the formats pre HD formats. It has infact 2 bassmanagerment systems one digital and one analog that is used in pure direct mode. I would first use the test tones to see if you have the correct output and volume is ok. Then check for speaker sizes and mode, you can select things like THX, LFE+MAIN etc etc.


Btw Effect/SB is the wrong output, thats Surround back (left and right) the one under center is the subwoofer, with the SW lettering.



Good luck,


Daniel.

I don't own a Denon AVR 5800 but given this information I feel I could be correct insofar as it being connected in the wrong slot...What I am curious about is if rlavalle is talking about a stand alone subwoofer or what is in his powered Def Tech towers, which I have no experience.

I think that you are thinking of the 5803 and the upgraded 5803A. I don't think that the 5800 had any upgrades. It doesn't even do Dolby PL II let alone PL IIx.

Here is a review I found stating it is a 7 channel AVR: http://ultimateavmag.com/avreceivers/12/

I believe Daniel was talking about actual codecs and not 2 channel re-processing.

Thanks for the info folks... it turns out I'm a moron.


The mention of an SW output finally clued me into looking at the manual more carefully. That's the output I need to plug the powered sub into. When I shifted the system around after years of using the first gen 65" Mitsu HD TV, switching to a 65" Mitsu DLP, I must have seen the Effect/SB and thought "Low Freq Effect/Sub".



Duh. When I get back home tonight, I bet when I plug the RCA cable into the SW output (under the Center output), I get my remaining '.1' of my 5.1


I'll test it on my favorite test scene: The Building Attack/Helo scene from the original Matrix.


BTW, the speaker setup is as follows:

Fronts: B&W 640i's

Surrounds: B&W mid sized, forget model.

Center: CC6


I have my speaker sizes set for:

Fronts: Large

Center & Surrounds: Small


This thread has helped in 2 ways: I'm sure my issue is fixed and I'll now try LFE + Main to see if the B&W 640i's can add and smooth the deep base.


Thanks!

Way to go!
Nothing like a cheap fix. ;-)

This does not sound like a good idea to me.
