Question about Yamaha RX-Z9 Receiver

1 Answer

Yahmaha rxz9 no output signal to sub

Hello, Just hooked up my new reciever and had the sub working perfectly. I turned off the reciever and left the sub on (new JBL L8400p) during the night I heard a low frequency hum coming from the sub. I unplugged it and the next day when I turned on the receiver I had no sound from the sub. I have checked the sub with another reciever and it works perfect. I set everything up in the gui as explained in the manual and still get no signal. I have also changed the cable with a known good one. Please help! I've been at this for 6 hours

    signal is coming digital from cable box or from blu-ray. It worked last night. I can hear an extremely low signal from the sub but it sounds full range not LFE. Thanks

    What are you attempting to generate the signal with? Test tones from the receiver, dvd with a 5.1 track, something else?

Trying to hook up a KLH sub woofer, S100ETH, PSW8-100 to a VCR reciever. Reciever has sub woofer connection but does not works on the KLH sub woofer. What is the problem ?


I suggest you go over your receiver set-up instructions. See if you need to set the receiver to acknolwedge the addition of the subwoofer. It should be in your receiver set-up steps. Just as a check, hook up one of your other speakers to the subwoofer lead to see if gets audio signal. I'm guessing the issue is your receiver settings.

How do i connect my subwoofer to my home theater


Easy. Your home theatre amp will have a sub or LFE output ( RCA plug ). You simply connect this output to the input ( usually the left side, or use a Y splitter and use left and right inputs, or the LFE input if your sub has it ). Then, you must turn the sub on in your recievers setup menu, and your sub should work.

I have a s108sp subwoofer with a right and left input assuming this is for a cable going to one input on my Sony reciever. The subwoofer also has inputs for speakers. Do I plug the speaker wires into...


Hey there houleo!
If your subwoofer has a stereo input and stereo outputs, then it's a good idea to send the signal from your receiver to the sub, then out to the other speakers you have hooked up. Some subwoofers will take the low frequencies out of the signal to the left and right speakers, so that the sub handles it alone. This often gives a nice crisp sound.

Sub doesnt do anything while plugged in ( Sunfire mk II)


Some subwoofers can sense the signal on their input and will only start when there's enough signal for long enough time for them to turn on the amp.

Try seting the "subwoofer signal out" on your reciever a bit higher, see if it does the trick, if not, try it with some other source (e.g. an mp3 or CD/DVD player) plugged directly into the subwoofer. If it still doesn't work, there's some other problem with your sub (bad connection inside sub, sub amplifier problems, maybe there's another fuse for the speaker itself, try to check it out).

If it works well with an alternate signal source, the problem might be either in reciever or the signal cable that you use, but could also be something else.

good luck

How to hook up my rem amp wire to this player it does not have


If by saying amp outputs you are refering to the RCA jacks on back of the head unit (Left and Right RCA jacks usually labeled FRONT, REAR, SUB, etc...) then you do have options even if your head unit doesn't provide a SUB channel.  These RCA jacks/amp outputs carry the signal (music or whatever) at a lower voltage (and is typically more like DC voltage as there is a ground reference which is 0 volts and signal rides on the positive voltage), providing a cleaner signal to the amp which does all the work.  The wires behind the amp that you connect directly to the speakers is typically amplified by the head unit itself and is a much higher voltage level and varies from negative to positive ( AC voltage.).

You could use the other channels (FRONT or REAR) if available, (a specific SUB amp output cuts all the higher frequencies out, passing just the lower subwofer frequencies inside the head unit).

if you want to strive for a more efficient use of your sub, use a low-pass/SUBwoffer filter (a crossover) in between the Head unit and amp, thus providing the amp with subwoffer signal, (or if for some odd reason you have SPEAKER level sub connections you can use a line output converter which will let you run RCA to the amp.)

Hope this helps u understand why I couldn't just say get a new stereo nor could I just say use splitters on available amp outs.

Still no sub woofer output


SET THE CROSSOVER TO "L.P.F."POSITION AND SELECT THE LOWEST FREQUENCY AS THE CROSSOVER POINT.
[AN AMPLIFIER IS SUPPOSED TO "AMPLIFY"(TO INCREASE)ANY OUTPUT.]

TRY CHANGING THE POLARITY OF WIRES FROM AMPLIFIER TO SPEAKERS /SUBWOOFER.{it leads to cancellation of bass output.}
if u still have doubt contact me again.

Subwoofer Connection: Speaker wire to Mono RCA


The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.
  1. Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
  2. connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
  3. make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
  4. leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.

You can even now turn off your subwoofer / adjust the volume easily now!
