I am using an Onkyo TX-8255 receiver with the ION Profile Pro USB Turntable and I'm hearing distortion through my speakers at all volumes. The speakers and the receiver work fine with the radio and the turntable has no problems when connected to my friend's receiver. So there seems to be a problem with the connection between the turntable and the receiver. Any ideas?

remove rca plugs from speaker wires and wire the speakers to speaker connections on the back of receiver. The receiver may already have a phono input for a turntable.

The Onkyo TX-8255 does not support any internet or Bluetooth access directly. You may be able to use the Onkyo remote interactive (RI) dock, DS-A5, to get the wireless streaming, if you can find one on E-bay or a similar resale site. See https://www.onkyousa.com/Products/model.php?m=DS-A5&class=Accessory . Onkyo has discontinued manufacturing these docks. The dock connects to the receiver via an audio cable. The features and manual for the Onkyo TX-8255 are available at the product page on Crutchfield, https://www.crutchfield.com/S-Q75dK8s0iLY/p_580TX8255/Onkyo-TX-8255.html . The current link to the manual is https://pdf.crutchfieldonline.com/ImageBank/v20080824133600/Manuals/580/580TX8255.PDF .

Unfortunately, if you can't find one of these docks, you'll need to connect use an audio cable between the TX-8255 and any dock for some gadgets or a direct connection for other internet connected devices. I wish that I had better news for you. Cindy Wells

Make sure you have not put it into tape monitor mode.

The problem is you are dealing with two different brands of speakers, I know because I ran into the same issues you are facing now, I had a Bose sub matched up with two Radio Shack Satellites and sound was not balanced it was awful. Finally I broke down and bought a pair of Bose Satellites and I have never regretted it since. The point I'am making is that when you mix brands the sound will be unpredictable, the problem with most subs is they have a very low roll off frequency even without the crossover making almost impossible to match speakers.

I had the same problem. You must turn on the remote speakers via the reciever and then adjust the remote speaker volume control that is only located on the remote control. The volume buttons are on the top right of the remote. It is briefly discussed in the owners manual which can be downloaded online.<!-- from fixya rte -->

Check speakers for distorted or dead drivers . Disconnect and repair. receiver will blown if not disconnected.

try to change the center speaker.
if the distortion happens when you rotates the volume control . clean the volume control using isopropile alchohal or any head cleaning solution.,

Try some troubleshooting to check whether its the turntable or the the receiver.

What happens if you exchange the output cables of the turntable from left to right. Does the problem shift?
Does the sound changes from left to right speaker?

Similarly try on the inputs of the Receiver.. does the problem shift...?
This way you will be able to isolate the problem, whether with the receiver or the turntable....

Let me know, we can trouble shoot it further....

It's the Tape 2 button - unclick it.

I have to ask the obvoius, did you get the manual, have you used the onscreen menu to set up the speakers, you can calibrate the speaker levels on the TV screen if you use the S video or RCA vidoe connection .have you turned off tape monitor?
