How the fudge to i connect this sub to my amp (Onkyo605)?

No idea where the setup mic is man :( Things get tidied away by the mother faster than anything, you tend to learn to work with one arm tied behind your back for them :D

I'm guessing its user error as well Howard :p, tried the level control and get no difference...

Subwoofer option is set to yes and i've fiddled with most of the options its just not actually that noticeable especially over the 4 ceiling speakers, you can hear it just about making noise. But even the level adjuster is not enough to even trip the auto on, on the sub, it just seems "quiet"?

There are bigger problems than this atm though, i need to track down a new Input circuit for the Sammy TV because the HDMI went on it ages ago and i've been routing everything through component and optical SPDIF don't know what difference that makes with the likes of DTS etc... although i should think it wouldn't it still means i've got about 12 extra cables i don't need!

This is why i hate coming home :p Cheers chaps, i'll try and fix everything up before i retackle this problem, then i'll update this thread if there are more problems sub related down the line. I do believe the sub and the amp are working they just aren't setup right :)
 
OK heres a few things, its most probably because you've missed something in the setup that the auto mic fiddles with. Finding that mic would make things mighty easier :p.

Anyway.....

Speaker types - Large/Small etc. Some amps, if the fronts are deemed 'Large' will send LFE to this aswell as a subwoofer. Somewhere in your settings you will have something like -
LFE OUT - Front/Sub/Both
Set it accordingly.

Crossover - This is the frequency at which the amp will send signals to your subwoofer. You'll notice this will be a dial on your sub also. Set this dial as high as it goes, set the volume as high as it goes also. Use the amps crossover and sub volume settings to calibrate (normally set by the mic!).

Also, get some DTS or DD through it, will make it much easier to tell whats going on, especially if you have decent floorstanders. Bare in mind, your fronts may well be up to the task of bass in a lot of songs, and the subwoofer may well be sparingly used. Get some thunderous soundtracks on there (Saving Private Ryan beach scene is incredible) and you'll soon know if the sub is on :p.
 
Also subs aren't supposed to be blow you away loud, it should integrate with the main speakers for stereo so you can't tell it's there.

For the LFE (low frequency effects) stuff, just find a DVD with test tones on and try some low frequency sweeps :)
 
Not sure if it helps you much, but under settings and speaker config, on my onkyo 606 this is what I'm running and it works perfectly. My setup was doing using the supplied audyssey mic - resulting in a good enough sound. I'm sure it could be better but 'it works' :)

As said above, on the sub whack everything up - well I'd turn the crossover up as that will be handled by the amp anyway. Also, you have By Pass set to ON... should this not be set to off? Though you say it worked when plugged into a CD player so it must be the right position.

you'll have to check the literature buy by-pass generally bypasses the built in crossover on the subwoofer itself, which is always the preferred option if the amp is handling the crossover.

if you getting bearly any output at +12on the amp, with the gain up full on the sub, then something is wrong with the amp. try another cable if you havent already to rule that out.

other than that, try a reset on the onkyo (hold vcr/drvr and power it up). just be warned that it, you know, resets everything lol
 
According to the manual for the VW8, when using a single LFE (Low frequency effects) feed you should be using the R input, not the L input.

LFE isnt a digital feed, its simply a pre filtered "bass only" feed.

The switches should be set to Auto (or on), Phase you set after its working, normally 0, but some rooms, and positioning of the sub cause it to be out of phase, in which case 180 can sound better. Finally the bypass can be set to on, which disables the built in crossover, and lets you set the crossover point on the AV amp instead. This avoids having multiple crossover filters in the path of the bass.

Monitor Audio make some nice speakers, and have had a pretty good reputation as a manufacturer of british hifi speakers for many years.

The reason the VW-8 comes with stereo inputs, is because its usable as part of a "2.1" Satalite/Sub music system with any amp that has stereo pre-out, OR part of an AV system with a single sub-out.

I have included a link to the user manual for the VW-8

LPF of LFE is a separate low-pass filter for the LFE channel in encoded material. 'sounds more complicated that it is, though im still not convinced it needs to be there at all.

for some reason, onkyo decided that you might want to set the the low pass for LFE seperately from the crossover on the main channels, and there are two schools of though on this. 1) you should hear everything intended by the producer of the soundtrack and 2) it should be set to match the crossover from the main channels.

I personally am firmly in the second camp. my sub woofer crossover over at 60hz - why then would i want to hear 60-120hz of LFE content on my favourite film? yes, content does get discarded when you set the LPF of LFE low, but if i dont then it just sounds....out of place as you can probably imagine, my sealed 15" is quite peaky about 80hz.
 
James...

I see what your saying :). I had assumed that most AV amps mix the LFE channel into any available full range speakers above the set LFE crossover point. I have my processors LFE crossover set at 50Hz, so the sub really only gets the lowest stuff, as my floorstanders dont even hit the -3dB point untill well below 50hz.

Nothing ever "seems" to be missing so I have not even given it a second thought :) But I am pretty certain that my AV processor diverts anything above 50hz on the LFE channel to my Left/Right mains.

But it does leave the question.. if you have small main speakers, which are filtered to avoid distortion, and dont let the sub fill in..

Just curious, dont you have a hole in your low frequency's.. Your front, center and satallite speakers are being filtered at 150hz, and your sub at 100hz.... Whats going on between 100 and 150hz! :)

I don't know :( I'm not very clued up with this - I just used the audyssey setup mic... worth changing?

I dont know much about Audyssey, but its room correction isnt it.. so it probably is able to set "hidden" settings which can probably close up the gap between the crossover points anyway. That said, I would imagine that most satallites could handle 100hz to some degree, or are there any settings inbetween like 125hz for both speakers and sub... And then let Audyssey do its magic again after you set that?

i've got a 605 and my subs connected fine via the stereo out jobby as yours is (its a velodyne )

Have you tried turning bypass off on the back of the sub ?, i think the Amp handles the bypass setting ?

I'd have thought 100hz is somewhere around the middle of the crossover setting on the back of the sub ( youve got it on min according to the picture), do you need to turn that around a bit more ( not sure what range your sub is )

I'd also turn the sub up a bit more on the back, again try the middle ish for starters and repeat audessy if that works.

Have you adjusted the channel level setting for the sub in the 605 and tried playing a 5.1 dvd etc , make sure your DVD is outputting via optical / coax and its sending bitstream etc out so its proper Dolby Digital or DTS .. the front panel on the onkyo should tell you if thats happening
When Audyssey plays it does play the sub quite loud , so you should hear it.

Thanks Corasik! (sorry OP for slightly derailing) I'll actually take a look at all the speakers and check their range and re set that, probably knock them down to 100Hz... Maybe do the same with the sub, though should 100Hz be about right?
 
After Running Audyssey , and you getting Fullband this needs changing to 80Hz (your already Rolling of near 80Hz Due to Onkyos Implementation of Audyssey)
Lpe-Lfe = 120Hz if using Audyssey ..

Recently added to the site http://ask.audyssey.com/home :)

Remember you can not Raise the Crossovers after Audyssey , But you can Lower them .

what do you mean by this?

you mean LPF of LFE, right? Audyssey has no bearing on this setting

I'm assuming the same, if the receiver doesnt have a separate setting the equivalent of LPF of LFE. i don't actually know for sure :p

That is what i mean , Audyssey Does not Adjust the Lpe-lfe on setup. This why 120Hz needs tobe Inputed.

you should no this Anyway James , with the Avs thread and Avf conversations ;)
 
you said 120hz IF using audyssey. my point was, using or not using audyssey makes no difference to this decision. You either set it to 120 if you believe you should be hearing everything, or you set it to match the crossover frequency of the main speaker, irrespective of using audyssey or not.


anyway, it was this i was referring to:
