Question about Audio & Video Receivers

Open Question

I have an old Marantz 2245 receiver. It has a single RCA jack on the back marked "Quadradial." I connected my subwoofer to this jack using a splitter cable to match the two RCA low-level input jacks on the subwoofer. It works just fine on FM radio. I recently added a CD player and it feeds through the "Auxilliary" jacks on the receiver. The subwoofer is silent when playing CD's. I re-connected the subwoofer using the high-level input jacks from the remote speaker terminals on the receiver. This works OK on all inputs including FM and CD. I would rather use the low-level input to the subwoofer. What does "Quadradial" mean? Why won't it work using the "Auxiliary" inputs? Olephredd

SOURCE: receiver works with digital signal input jack only.

Are you talking about the 6 channel input with all RCA jacks? Please explain a little better, it is very hard to know how you have it connected without a very good description since I can not put my eyes on it. You may need to check the settings, it may have the rears muted. More information from you will help me to be able to help you.

SOURCE: No Soound on Subwoofer from Yamaha RX-V363

I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

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.

SOURCE: Old receiver, new subwoofer- how to connect?

NOOOOOOOOOOOOOOOOOOOOOOO! Never connect speaker outputs to anything that looks different, like RCA connections. Can you say crispy critter?

Your receiver sounds like it won't send specific Subwoofer of Low Frequency Effects information to the Sub so we're cheating by adding a sub. If you named the model of each we may have a better shot at naming the output you need to use.

I'm curious. How did you have the old passive sub working?

Basically what you may have to do is feed (probable) full range audio to the Sub using an RCA splitter to combine the L and R outputs found, oh, at any Tape Output that you're not using. The Sub will only reproduce what it can. The presence of higher frequencies won't bother it. If it has its own volume control you'll be able to balance its volume with the rest of your speakers.

I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

Marantz SR-66 Shut down!


Sounds like the protection circuit is tripping. With power off, check for loose speaker connections. Also, look very closely for shorts in the speaker wires. Even a single loose strand can touch another connection and create a short, which shuts down the receiver.

I would take take the frequency splitter out of the circuit and see what happens. Check for acceptable impedances in the manual. The receiver may not like the load the splitter presents.

The receiver may have settings for bi-amping. Then you use one set of terminals on the back for treble, and a different set for bass.

My reciever has only one jack for the sub out but my klipsch sub has two jacks (left and right). how do i run the cable to set it up ?


Use a Y splitter , 1 RCA to 2 RCA
OR simply connect just 1 RCA to ! RCA
OR use a 2 RCA to 2 RCA from the receiver's pre out.

How can I hook up my jvc rx-6018v to a gemini xga-2000 amplifier?


you can do it a couple of different ways, depending on what you're trying to do with your set-up.if you're trying to do something different than what I describe here, add a comment.
for independent volume control (each unit contols volume to a set of speakers independent of each other) use the rca 'tape' out of the jvc into the rca inputs on the back of the gemini.this puts a stereo signal from the jvc to the gemini. if you want your gemini to power your subs, get an rca y-splitter (single female to double male) and a single rca cable, hook single rca cable to sub out of jvc, connect y-splitter to gemini rca inputs, and single rca to y-splitter.

Which jacks to wire the subwoofer to?


Your receiver should have an RCA connector on the back panel that will be marked "sub woofer" or "LFE out". That connects to your sub woofer with a standard RCA type cable. Also, some powered subs have left and right speaker level inputs and outputs in which you would indeed run the sub woofer through the speaker outputs. The down side of that type of connection is that the line level converter inside the sub woofer will take a slight amount of your receiver's output power, although that is rarely detectable. Also, if you have a Dolby Digital receiver, using this connection method will take away systems ability to accurately control the low frequency effects of a soundtrack.

Good Luck,

Speaker wire for subwoofer


Usually, a subwoofer will have its own built-in power amplifier. Thus, it will be designed to plug into a standard RCA jack (the type used for DVD players, etc). rather than having wires to connect to a speaker terminal block. Look for a jack on the back of the receiver called "Subwoofer", or simply "SW". If your subwoofer has 2 single wires, it WON'T work with your reveiver's subwoofer output, as this output only carries a line-level signal and is not amplified. You would need a separate power amplifier for this type of SW. If your SW speaker has a DVD-type plug, it should work fine with the receiver's SW output jack.

Yamaha RX-V1200 subwoofer connection to Mirage BPS-150i subwoofer


just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out
