No signal coming from sub woofer out

Normally the sub woofer is driven by a separate amplifier, unless the main speakers, such as in a pro audio setup have a special LF out set of terminals on the back of the speaker cabinet, in this case there is a hi powered low pass filter, fitted in side the speaker to route the LF energy to a sub woofer. Else you need a line lever LF signal spliter and a power amplifier to connect a sub woofer.

Usually, it's the "stereo-audio-output" from your amplifier that goes to the sub-woofer, and then outputs from the sub-woofer to the left/right speakers. Or, if your amplifier has a separate output labelled "sub-out", then your connect your sub-woofer to that mono-channel output.

if you have your front and centers set to 'small' you want your Bass out to be subwoofer only, and the rca jack labeled 'sub out' is the only place to connect your sub to if you want to control the frequencies with your reciever. I dont know the brand of your sub, or the inputs on the back of it to advise you where to connect, but it sounds like it worked for you at one time, but suddenly it does not

Hello
There are four possibilities that the subwoofer doesn't gives any aoutput. They are:

• Subwoofer's power not turned

on.

•The "Subwoofer" setting at

"Speaker configuration" is set to

"No".

•The subwoofer is not properly

connected.

•The subwoofer's volume is
turned off.
Go to its manual setupscreen, come to speaker setup, speaker confuguration, come towards Sub Woofer, select "Yes" and press OK.

hi,
if u want to hook up the sub with ur av receiver the connect the sub woofer output of ur AVR to any one (left or right) input of ur sub woofer. then connect its power . set the frequency range between 90 and 120Hz. set the volume of sub woofer to 40% of its total. also check the av receives speaker setting. goto speaker setup and make ON the sub woofer out.

if want to connect the sub to a stereo amp without sub out. then connect the amps speaker line to the speaker input of sub woofer and connect the speaker out of sub to left and right speaker ( make sure to connect the red to red and black to black). set the volume and frequency as above
ok

hi,
first of all check ur sub woofer is it working or not. for that pull out its RCA connection from the receiver. power on the sub woofer and touch RCA's middle pin with ur finger. if its working it will produce a hum. if ok, go for the next,

do the following setup in ur av receiver
press menu and select manual setup and press enter
in manual setup select speaker setup and press enter
in the speaker setup select sub woofer and turn it on .
ok

Please recheck the connection of subwoffer once again..
thankyou...

i have the same tuner.on the back you will see all connectors bottom row of rca jacks you will see subwoffer if your sub has to rca. red/white use a splitter monstor cable gold ..works best. i use Home Theater Reserch speakers... you can also plug your subs power plug into the tuner snd you never have to power it on seprate .........

Some systems don't send signal to subwoofer if speakers in SPEAKERS SETUP are set to LARGE, they redirect signal to center and front speakers. Maybe that's problem.

If sub has two signal outputs and if the monitors are full range (passive crosover built in), put mixer outputs to the sub and signal outputs of the sub to amps in.If not mixer outputs to th amp and its signal outputs to the sub in.Or you can use main out of the mixer for the monitors and rec out for the sub.Its just few XLR or jack cables extra.Just make sure that the mixer,sub and the amp are on the same power phase otherwise you'll have brrrrrrrrrrr on the speakers
