Wired my Jamo Sub650 from a pioneer VSX1017TXV reciever using the subwoofer line out to the "LFE" on the subwoofer and get no sound. Used the Jamo supplied line cable. Any Suggestions?

Is everything hooked up correctly sounds off I know also could be your amp is going on you cold be a multitude of problems or one of the simple ones i stated
The problem is in the powered sub, the buzzing sound is caused by one or more defective audio output ic's that drive the subwoofer directly, service is the only option to remedy the situation.
The Jamo is self-amplified and accepts Line Level input ONLY.
The HTP-2500 receiver drives a subwoofer directly with SPEAKER LEVEL output only and does not have a volume-controlled output for driving externally-amplified devices.
does this sub have an LFE output? if so, connect that to the LFE input on the reciever and make sure it is set up properly in the set up menu in speaker configuration. if the sub has speaker line input outputs, connect speakers to input of sub and out of sub to amp/recvr
What do you mean that it sometimes doesn't work? It doesn't power on automatically? Check settings of your receiver - if it has subwoofer output enables and if low frequencies from all channels are directed also to the SUB. By default only the LFE channel (.1) of 5.1 signal input is fed to the subwoofer. So Sub will work in this case only when you listen to 5.1 signal (DVD movie for example), but for radio or stereo music, only front speakers are used. By configuring this bass redirect, you can use subwoofer for all signal types.
Usually the LFE out is only a line out and is not amplified in any way, so first of all is your subwoofer self amplified or not? Cause if not, the LFE output won't be of much use to you. So if it's not self amplified you need an new amplifier to put between the receiver and the subwoofer. Any amp that supports RCA line-in input will do. Even a car stereo amplifier will work provided you can get a 12volt power supply to run it in the house. If the subwoofer is self amplified though, then all you need is to make an adapter cause none are readily available in stores to go from a RCA connector to 2 wires. You can buy a virgin RCA connector that you can wire yourself at The Source, Circuit City, or any electronics store you have locally, or if you have an old RCA to RCA wire you don't need anymore, you can just cut it in half, strip the 2 wires and you got you adapter right there.
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!
Dual Voice-Coil
The unique Dual Voice-Coil design allows both left and right channel
sound from just one speaker. Simply hook up both the left and the right
channels to the special terminals on the speaker. Hook up one channel
only, if the speaker is to be used in a conventional stereo set-up. I found this on jamo site hope that will help you
check all your plus sign and minus sign that connected to the receiver , if connected wrong you will not have any bass,because it going backward. Good luck!! any quest email me [email protected]
