Onkyo skw 150 powered subwoofer output code

Oknkyo SKW-791 has build in amplifier. So it can be connected through Line Out Connector of sansui amplifier. If speakers out is connected with subwoofer, the circuit board in subwoofer will be blown.

You need a RCA sub-woofer cable (analog mono) to connect between the receiver's sub-woofer Pre Out and the sub-woofer. This cable has a single RCA plug at each end of the cable. The cable is somewhat thicker than some audio RCA cables. You can use any RCA cable temporarily.

The manual for the HT-R758 is available from Onkyo here: https://onkyousa.com/ht-r758 . The current link to the manual is https://assets.onkyo-av.com/product-manuals/HT-S6500_English_2022-11-02-204020_ivkn.pdf?v=1667421620 . See page EN-13 (page 13 of the PDF) for connecting to the subwoofer. The original package came with a 10' RCA sub-woofer cable, see page EN-1 (page 81 of the PDF) for the speaker list.

I hope this helps.

The thumping sound might be originating from problems within internal parts, like capacitors or resistors, which could be contributing to the issue

Hi Kenny, sorry you can't. The TX=SR505 requires a powered subwoofer. The SKW-360 is passive. Thank you, Onkyo USA

It would seem that a call or email to the mfr, should be your first move.
Are you certain that the transformer is at fault?
These normally outlive most everything else-

does the green light power up on the back? If not the power supply is bad

It's possible that you have accidentally switched off the sub-woofer outputs on the receivers. Onkyo have a speaker set up test. You should run that and see if the speakers are on and that a signal is getting through to them.

sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty
damaged sub woofer eg. torn cloth-
Thanks for rating good luck

You amp has no OUTputs for a sub, but if you really want to attach a sub you'll need to get one that is self-amplified and accepts >>>stereo<<< High Level or Speaker Level inputs.

Otherwise your amp's volume control won't also control the sub's volume.

You would feed it full-range audio from the speaker terminals on your amp and its internal amp would use that to develop its own power output for the sub.

Here's one example.

The amp output stage or the power supply is shorted. Service shop type repair.
