Vij, here is my best guess: The disc may have been mixed without LFE content. This isn't uncommon for multichannel music. To be sure, pop in a DVD-A/SACD that you know has subwoofer content. If that disc is as bassy as it has always been, then you have nothing to worry about. Perhaps, you could use bass management(in the player or in the receiver) to send the left & right channel lows to your subwoofer along with whatever else is running to it now. If this doesn't work, then you may be hooking up the sub with speaker wire from left & right speakers(not just LFE pre-out). In this way, you won't need to worry about the mix on each individual disc, anymore. I hope this helps. Let me know how it turns out?
I was watching the "speaker setup" of a recent DVD-A purchase (Tom Cochrane & Red Rider's "Trapeze") and there's a part where a voice is coming out of each speaker with a graphic on the screen to tell you out of which speaker it should be coming. Everything was fine until it got to the subwoofer. When the voice said, "subwoofer", the voice came out of my centre speaker, and at a slightly lower volume than with the others. I then unplugged the centre speaker from my receiver to hear if anything was coming out of the sub -- nada. I even turned up the volume of my sub all the way (even though it shouldn't matter -- when using the "Direct In" of my sub, the sub's volume control is overriden and the receiver's is used), and still got nothing
I've got subwoofer cable going from the "Direct In" of my Athena AS-P400 subwoofer to the "Subwoofer Pre Out" of my Yamaha RX-V750 receiver. I've also ensured that the analog cables from my Pioneer DV-588A universal player are correctly hooked up, going to the multi channel input of my receiver.
Has this happened to anyone else? I remember someone saying that correctly balanced bass isn't noticeable in music. You notice the absence of bass by the music sounding thin or airy. I didn't notice any bass in the music, but I guess that just means that it's perfectly balanced on the disc.
So if I don't notice it in the music, then that's good. But why does nothing come out of the subwoofer when the voice on the speaker setup says it should? Thanks for any help!
L Alpert, I definitely made sure the subwoofer was switched on in my DVD's setup. I also had all the speakers set to small.
Nselson, you may be right about this particular disc being mixed without LFE. Although it does say 5.1 clearly on the cover. I went back and listened to a couple of advance resolution tracks and the receiver on "multi ch input" and the little light on my subwoofer never came on (it blinks on when it receives a signal). Then I listened to one of the DTS tracks and the receiver on digital input (I've got a crossover of 80 Hz on my receiver) and not once did the subwoofer's light come on. To be honest, I've never noticed my DVD-As nor SACDs to be terribly bassy, so I can't really compare it to anything.
But yustr may be onto something . . . I think maybe my receiver can't handle bass management when using the analog inputs, and here's why: I popped in my Blue Man Group "The Complex" DVD-A, and listened to some of the DVD-A tracks -- the subwoofer didn't receive a signal. Then I listened to a DTS track on the same disc, with my receiver accepting a digital signal and with the receiver's crossover set to 80 Hz, and sure enough, the subwoofer DID receive a signal. And the point in the song that it did receive a signal for DTS, it didn't receive a signal for DVD-A. Which makes me think that my receiver doesn't do anything with bass regarding the analog inputs. In fact, I'm sure that's it, cos I listened to that same track on DTS, but with my receiver set to multi channel input, and the sub didn't receive a signal.
Man, this sucks. This means that for SACD and DVD-A, I no longer have any bass. I don't want to hook up the sub to the front speakers with speaker wire -- I've got too much clutter back there, and it's a pain to clean. I think I'm gonna try using the bass management in my player: I'll set the fronts to "large" -- even though they go down to only 35 Hz. The centre (down to 60 Hz) and the surrounds (down to 50 Hz), I'll leave as "small". I'll try that for a while and see how that sounds. yustr, I also like your suggestion of hooking up the sub directly to the player. I'll try that too.
Thanks for all your suggestions! You guys are stellar!
yustr, your suggestion of hooking the sub directly to the player -- would the sub receive much of a signal? I mean, the whole idea of using a receiver is to amplify the signal; otherwise, it's gonna be pretty weak. And I'm not sure I want to get up and manually switch it every time. It really works for you?
Okay. I figured it all out. I had always thought that when using the multi channel inputs, I'm bypassing everything in the receiver: all the speaker levels and distances, the crossovers, everything. I figured that in using the multi channel inputs, I'm using only the settings on the player. So imagine my surprise when I go back to my receiver, increase the gain on the sub . . . and see the subwoofer blinking on when using the multi channel inputs. (I'm not proud of being this stupid. Really I'm not.)
The weird thing was, the settings I had previously worked very very nicely with movies and DTS music, as well as 2-channel music. I guess now I have to up the gain on my sub whenever playing hi-res music (I'll check later to see by how much). What a pain! But at least now I know.
Thanks again, everyone. I feel like a total bo-bo head on this one.
