I cannot get my sub to work with this receiver. Everything seems to be hooked up right. I have a VMPS 215 sub w/ a Parts Express sub amp running to it. Any ideas would be appreciated.

Are you using the DVD Multi setting and inputs?  Your source has to have discrete analog outputs (usually 5 or 6 channels and a sub out) into the discrete analog inputs on the JVC.  If, for instance, you are using two channels and a sub, you should have 3 IC's running into the JVC.

If using optical or coax digital connection (not as pleasing as analog input sounds), you choose 'digital' on your remote and set levels for sub to work.

I am using the multi in. So I can't connect the analog outs on my player to the multi in's and the plug the sub into the subwoofer output on the JVC? WHat do I plug my plate amp into?

[TheChairGuy]

If using 3 channels for eg (stereo and one sub)...you'd put your main channels in the DVD/DVR inputs, the sub in the subwoofer input.  Then, your speaker cable to your main channels left and right and another IC from the subwoofer out on the JVC to your subwoofer (plate) amp.

(I believe) You lose the ability to set the levels of the sub to match your main channels this way; which is a major drag if you're overall preference is to have the sub integrated into your listening.  The upside is that your main channels never sounded sweeter with a  $250 amplifier before.

When I have my sub on (very rarely), I simply have it on pretty quietly for a bit more 'foundation'.  I genrally only use it for reggae and orchestral pieces.

Hope that helps.

I could be wrong on this point, come to think of it...it's been too long since I mesed with anything on the JVC.  I love it just as it is.

Perhaps you can set levels in the JVC for your sub...otherwise why offer a sub in and out?  Yuu could just plug your player outputs directly into the sub plate amp...making the path simpler and purer still.

I have a Modright tube modified 999es. When I go from the analog outs of the player into the multi channel ins of the receiver and hook my plate amp into the sub output on the receiver I get nothing from my sub. I can't get a peep out of my sub this way. I'm not using the 5.1 analog imputs on the player because that would bypass the tubes.

Sweet player Gongos...I got a bud with one and loves it.   Man, I love that your running a player many times the cost into the JVC.  My front end is about $4000 and I couldn't be much happier running into the $250 'Little Wonder'.  Well, maybe a little...we have to leave a little wiggle room for upgrade-itis in the future  

I'm a bit perplexed myself.....you have checked to make sure your sub and sub amp are working, right?  Just take the sub out from the Modwright directly to your sub and see if you get sound this way.  If you do, it's the likely best way to hear it...entirely bypassing the JVC in-between.  Or, are you saying that in doing this you will bypass Modwright tube-goodness?

On the Modwright, are there separate/dedicated 2 channel outs AND another set of  5.1 channel discrete outs...only the 2 channel analog outs have been modded? Is that what I am understanding?

Are you sure that the analog outs have not been defeated entirely and that they still operate?  I suppose a purist-oriented modder (I'm not sure if that is what Dan is) might defeat the multi-channel outs for purer stereo reproduction - I s'pose.

[gongos]

The 5.1 outs work and have been modded to some extent, but the tubes go through the analog stereo outputs so if I use the 5.1's the tubes will be bypassed. I'll try the sub right to the back of the player.

[mcgsxr]

From my short time with the JVC, I recall that you MUST use the multi inputs to get any sub.

Could you run the tube outputs into the Multi L and R, and then the sub output from the player, into the sub input of the JVC?  That should make some sound.

Or, I misread how you are hooking this up, and I am suggesting that you do what you already are... ow, my head hurts!

Yep, let us know.

I know what ya' mean Mark   , it's tough diagnosing without knowing or having the playback equipment and/or sub/speakers right in front of you.

[gongos]

Here's what I've found out. I've used the analog out of my player into the multi ins. I tried to hook up the sub to the 5.1 subwoofer out on the back of my player and got nothing, which is probably because I'm not using a 5.1 SACD for playback so no signal is traveling to the amp. I then tried to plug the sub into the 5.1 front output of the player and that resulted in some bass. So now here's what I have. The stereo analog outs of my player hooked up to the multi ins of the JVC, and the sub amp directly plugged into the 5.1 front output of the player, bypassing the receiver. Now if I want to watched movies through it I have to change the sub wiring everytime.  I'm still trying to figure out how to get the damn sub hooked up through the receiver. New problem!: just before the CD starts to play my speakers have a strange crackling noise go through them. I guess another option is to hook the stereo outputs into the VCR ins-the sub works through the receiver when it's hooked up this way, but everyone says the multi ins are superior. If this doesn't work out I might try Kenwood.

A couple thoughts, in case you haven't tries these:

- Make sure you have the subwoofer turned on in the F10 setup menu.  Using the front panel buttons, you click the Setup button on the left, and then use the input selector  knob to move among the choices.  The other front panel buttons also have functions for setup, but I'm not at home so this is from memory.  When you get to the Subwoofer choice, make sure it's on.  There may also be other subwoofer-related items in this setup function.

- You may have to use something other than DVD-Multi to get your subwoofer to work.  Have you tried the regular DVD choice on the input selector, with your sub hooked to the subwoofer out and your speakers hooked to left and right out?  If this works, you should also be able to set the crossover frequency.  It won't sound as good as the DVD-Multi, but if it works at least you can try it out to see what you think.

KCK has successfully used a subwoofer and two speakers with the F10.  Hopefully he will see this thread and post to it.

Edited to add: If you switch from the DVD-Multi to another amplifier circuit in this amp like DVD or DBS, you probably have to do the setup menu again to make sure the sub is turned on.  I think the F10 saves its choices  independently for each amp circuit.

#1 is all good.

I can use the non-multi inputs and get the sub to work, but that's not really what I want to do.

[JohnnyLightOn]

I just looked over an e-mail from KCK about this.  Here's what he learned from his F10:

"First observation on the multi - it does not play the subwoofer, regardless of settings. Front = large, front = small, sw set = LFE, LFE+Main, nothing. I do not have time at the moment but will review the manual later; maybe it is in the threads also."

I will e-mail him in case he was able to make it work.  But my guess is that there's no way to do what you're trying to do.    

[gongos]

I guess I'mm a/b the multi and other analog inputs without the sub to see how much of a difference there is between them.

[ooheadsoo]

Wow, still confusion over this topic?  In mch mode, the sub only works if the sub input is fed a signal.  You can deal with this either by running the sub off the speaker level or you can use an rca splitter/joiner to split the signal to the sub input from your tubed output.

[TheChairGuy]

ooheadsoo reminded me of the splitter....which, DOH!!, I use    

It's a decent way to get your sub in line with the main channels, but make sure you buy an all brass one with a teflon liner (ACI here on AudioCircle makes a nice looking one).  The wire type Y-cable splitters muck the music up....at least the Monster Cable one I got a while back.

I might just be an idiot, but what does running the sub off a speaker level mean? What would I be hooking the sub RCA to?

[ooheadsoo]

You wouldnt

If your subwoofer has speaker level ins, you would just split the jvc's front speaker outputs off to the subwoofer instead of using the jvc's internal sub management.

[gongos]

No level ins on the sub so it looks like I'm stuck with the splitter option.
