Question about Pioneer VSX-454 Receiver

Multiple speakers in same outlet

Is it ok to hook up two sets of speakers in the same channel? (not sure is "channel" is the correct termanology.) Is there a devise that can be attached to my receiver so more speakers can be hooked up to it? I only have a place to hook up two sets of speakers.

How this reciever is set up is there are left and right A and left and right B Only one 8 ohm speaker should be attached per outlet. if you exceed that your driving the channel at a much lower resistance then the units designed for and the channel will burn up.. Oh it might last a short time but bet your last dollar it will burn up the channel if you over load it. Please dont forget to rate this.

I have a similar issue...i have a decent sound system, mix and that i mean, i run a cable from my laptop, to a mixing board, then from there i run 2 cables to my stereo system, which is hooked to 2 speakers....basic....but i have 2 more speakers that the wires from each speaker are split to another 2 subwoofer enclosure...would 2 splitters do me fine if i do so decide to hook up the last combination to the stereo?

The suggestion is correct for Amps designed to run at 8 ohms. If you amp, like the Onkyo 8511 that I was attempting to search on, is capable of driving 4 ohms, then go for it.

I don't know how "Techman" got a "Guru" rating but his answer is completely stupid. The manufacturer rates the speaker outputs for 8 ohms. Plenty of people have reported running 6 ohm speakers just fine. What few people realize is that this impedance rating is not fixed like a resistor, it changes based on frequency. Anyway, all the rating means is that you have to keep the individual total speaker output rating near 8 ohms to avoid over or underloading the amplifier channel. You could put two 4 ohm speakers in series (some dual voicecoil subwoofers are manufactured this way on purpose), or two 16 ohm speakers in parallel. You could put four 2-ohm speakers in series, four 32 ohm speakers in parallel, two 2-ohm speakers in series with two 16 ohm speakers in parallel, etc etc etc. As long as the equivalent resistance presented to the speaker output is around 8 ohms. Also if you underload (present more than 8 ohms) you won't "burn up" anything, you just won't develop the maximum volume potential of the amplifier out of the speakers.

Hooked to surround sound, two front speakers, 4 wall speakers, 1 sub woofer. Restart unit and reduce volume unit is OK but normal talking is too low.

Voice tracks are usually routed to the center channel. You don't mention having a center channel speaker hooked up. If this is the case, then you need to go into the receivers setup menu and set it for no center. This will reroute the voice tracks to your front speakers.

2004 escalade speakers work but not left side balance on deck is ok all chiming sounds are from left side Are there fuses on central amp Fuses in hood ok Fuses in dash ok

If your wires are hooked up correctly then it is possible you have blown a channel in your amp or head unit , the amp does have its own fuse but most do not have a fuse for each channel it either works or doesn't . Only other possibility is somehow the amp has been switched to mono .or "bridged" these settings are used when the amp powers only one channel or a subwoofer

How do I connect jWin JS P701 to my existing appliances?

That is such a goofy speaker set up and a first for me.

OK here is what is going on. This is a powered speaker set with no Dolby decoder. It will accept for surround only 3 sets of RCA's from a DVD player. I will include a link to a DVD player that has theses so you know what to look for. Make sure to look at the back panel image.

This speaker set is really just a modified PC set of speakers.( note the three mini to RCAs adapters only available in the box mind you).

If you don't want to get a new DVD player you can get a home theater receiver with what ever digital audio connection you have, as long as the receiver has pre outs to hook up to the speaker set. Will include a link to the one that has this.But that is counter intuitive to buying a powered speaker set.

Your only other option is to hook to up to a PC with the correct 5.1 sound card.

If it is a new purchase I suggest take it back and get a 5.1 system that will work with your existing equipment.

PS also look up white van scam I think you may have been had.

Left internal spkr not working

Try connecting an external set of speakers or headphones, see if you get both channels, if you do, then the speaker assy is bad and needs replacement.

If you only get audio on 1 channel externally, then check all the sound settings in Control Panel (make sure correct speakers are selected and the playback settings are all correct.)

Emerson Television

With a cable or DTV converter box hooked up, the only channel the TV will find is channel 3 or 4 (depending on how the box is set). Make sure the set is on the right channel and you should be OK. Also make sure the cable is good. If you have several TV's connected to the same source you might have a bad cable or splitter somewhere in the chain. Hope this helps!

No dialog sound when watching DVD's

The problem is that your center channel is not functioning correctly.  Dialogue is typically routed to the center channel only in 5.1, so if you don't have a working center channel all you will get is sound FX and background sound.
Go through all your settings, verify that they are correct.  Verify that your center channel is working properly, and wired to the correct output.
Test the center channel speaker and I feel confident you will find something amiss.
