Question about Pioneer VSX-D514 Receiver

1 Answer

Subwoofer preout and bass

My subwoofer is a different brand (TR-8200), but has L/R inputs that I use a Y connector to my receiver subwoofer preout. I also tried sending my front speakers through the subwoofer then into the receiver....Nothing! I've tried all different settings in the receiver itself from changing speaker sizes to PLUS and still nothing. No bass or sound (except I can tell it's on) coming from the sub woofer and hardly any bass coming from the 5 speakers. I tried to individually increase the bass through the reciever to each speaker, hardly made a difference. This system was working fine until I moved it from the basement to my first floor. Never banged it and it's not blown. What did I miss? Please help. Thanks

Re: Subwoofer preout and bass

Did you tell the receiver that you have a subwoofer connected (thru the quick setup)?

How do I get the powered subwoofer to work with a pioneer VSX-D510

You plug a subwoofer RCA cable into the Subwoofer Preout from the back of the VSX-D510 and to the input on the back of the subwoofer. If there is a red / white connection don't sweat it, just use the red. Should work fine.

I have a Pioneer VSX-1123-k receiver and a Klipsch SW 450 subwoofer and the connection is not clear. Can anyone help?

Should be an rca connector on the back of the receiver marked subwoofer or sub preout. connect that to the rca connector on the sub and it should be good to go.

Zone 2

I would consult your owner's manual but I don't think you can adjust the bass/treble levels on the zone 2 outputs.

I have a velodyne VA 806 subwoofer which I would like to connect to my AV receiver Denon AVR 391. In my receiver, I have a subwoofer out female connector (one) and where do I connect this line to the...

Get an RCA Y-adapter to feed both INputs on the sub. Define the sub in the Denon and set your other speaker settings as required to redirect the bass/LFE if they can't handle it.

Where do my subwoofer speaker wires get hooked up to on the back of the reciver vsx-815 ??

Hi there, the Pioneer VSX-815 amplifier only feeds out a mono LINE LEVEL output with the subwoofer signal. Therefore you would need to connect the SUB PREOUT jack at the rear of the unit to the "line level input" on a self-powered subwoofer. Hope this helps.. Cheers, Yusuf

Cant get bass, fuse is fine

You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.

Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.

Can I use front preouts for subwoofer?

First, you have to have a self-powered subwoofer (or two) with this reciver. That means the sub has its own amplifier. These are usually capable of accepting either Line Level (RCA) input or direct L and R amplifier channel speaker wires from your receiver from which it will react only to frequencies in its range. It doesn't actually use any if the power from your receiver's amp.

That is why you can extend your front speakers from the sub. Again, understand this - it is not playing any part in amplifying them. The amps in your receiver are just passing through it.

Setting your speaker 'Type' definition to Large will tell your receiver that they are capable of real bass (as opposed to small satellites) but won't necessarily steal anything from the subs. Set your LFE/Bass Out setting to Both if your front speakers are capable of handling real bass. Why would you want to deny them bass if they can handle it?

This part is confusing "If I can get the sub working on taking the lows out of the front speakers if I set them to large on the receiver then that is one thing less to send to the other sub on the LFE channel". The crossover feature allows you to define what bass goes to the sub. You would use the various points to smooth out the transition between your sub and the rest. Your quote of 47hz spec for something doesn't suggest your other speakers are great bass reproducers. One needs to see the +- db spec with less than x% distortion for that number make any sense.

Your receiver has two RCA Subwoofer Outputs but I'm sure they get the exact same level. If you're having trouble matching two different subs doesn't at least one of them have an adjustment for volume? Or maybe you could use physical positioning to adjust their comparative volume.

Very low ouput from subwoofer preout

The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
