Onkyo Pure Audio with Sub?

[TulsaSKD]

So when i connect using "High Level Inputs" i leave the Pre-Out LFE wire connected as well?

I dont think you have to have the LFE wire when you have the speakers plugged right into the Sub.

NO. One at a time.......... at least on my old BASH amp I would Not leave them both hooked up. Maybe someone that has more knowledge of this then I do will post up. Two signal at one time to my subs amp ????

ok i wasnt sure if maybe LFE had slighty differant signal for film and HiLevel was really intended for Music.

Didnt want to be missing any audio tracks.

Use EITHER the speaker level route OR the LFE/line level route. NOT both. Using both may or may not work and/or damage may occur. Do you feel lucky?

As for this "pure direct" or whatever they call the "straight through with no digital intervention" scheme on your receiver, the goal is to pass the signal through as few processes as possible. When you choose the "pure" signal, you forgo the LFE processing. That means no sub-woofer signal.

It's a choice you need to make.

On my newest Yamaha AVR RX-V1900 HD 7.2 it has a "Pure Direct" mode no LFE or processor to amps just pre/amp and amp are used. But this AVR also has a "Straight" mode no processor but my Subs work. So I can have my Subs wired with LFE cables and use them or not on these modes that by passes the Eq chip etc. I use to have tube seperates 30 years ago and we did not have a Sub I was Suprised how nice the wimpy Yamaha AVR amps play my old Cornwalls.

The OP may not have LFE signal thru the speaker wires but it does have ALL the signal. My sub in the bedroom just plays the Bass signal and sends on the complete signal to your front speakers. So he can have the sub on while on his "Pure" mode. Yes he needs to plug and un plug his sub when he changes to a Bluray etc HDMI being used.

This is the most "pure" way to pass a stereo signal through the receiver. This is what the "audiophiles" want: The signal, as pure as God intended with no additional processing. In such case, this choice means you get out exactly what you put in. Stereo has NO LFE channel to begin with so nothing is lost. It pays to have good mains here. If one doesn't, then one should not be playing the audiophile game here.

But this AVR also has a "Straight" mode no processor but my Subs work.

This does imply a minimum amount of signal processing to eke out some sort of common bass channel from a stereo signal. It's not pure but, to me, if it's available it presents a decent compromise, particularly if the mains aren't up to the task of handling the full range required for satisfying musical enjoyment. Whether or not this will still allow one to claim the highly desired "audiophile" status, I don't know, but that's a decision everyone has to make for themselves.

Of course, if one doesn't have something akin to this "straight" mode you describe, then the option still exists to run the sub at the speaker level, set the receiver to "no sub-woofer", the mains to "large", and take it as it comes. All the music, or whatever, will be channeled to the mains and the sub will still pick it up, albeit without any fancy bass management. This would work great with the "pure direct" mode that audiophiles love.

I personally use a sub but run the mains full range and use the crossover in the sub as a low pass filter to only send what the mains can't handle to it and, for music, use the "stereo" mode. Like Sholling said, I don't hear any difference between this and a more direct mode. I don't worry if people consider me an "audiophile" or not. I've been playing this game to long and have enough confidence in myself to worry about labels.

As long as you're in stereo mode and not one of the artificial stadium type modes I doubt that you'd be able to detect any processing other than Audyssey room correction.

i would never use anything like that ever, im fact i dont even know why that is even an option and why people would want to use it.

but yes that is all i have set is room correction.

I think my main problem the limited space in my room is my speaker position i can hear the bass fine i just dont feel the bass though my body i find the way 'markw' said "run the mains full range and use the crossover in the sub as a low pass filter to only send what the mains can't handle to it and, for music, use the "stereo" mode." works the best for me.

it doesnt take anything away for the fronts and adds a fullness to the sound in the room with out being over powering

I change the crossover to the 50Hz for music and set it set back to 80Hz for movies.

You clearly don't want Pure Audio because you want the receiver to do some processing. Your objection is philosophical and not practical.

No. I used pure audio in another room with the same equitment and it is fantastic.

Problem is this my room has limited space and speaker position isnt great at all which is preventing me feeling the bass.

sure it not PURE but i want to get as close to pure audio with minimal processing as possable until i can fix room layout. which i have gotten.
