How do I hook up my blue tooth headphones to my onkyo SR 605


You cannot rig up a blue tooth headphones to this receiver with out a blue tooth transmitter ( the Onkyo does not have one built in ). If you have a transmitter it can be plugged into the headphone out socket of the Onkyo ( in front ), just remember that it will cut out the sound from all your speakers when you insert the headphone jack . The advantage though with this connection is you can control the headphone volume using the Onkyo remote.

I cant get the surround sound to work after connecting the Samsung BluRay Player to my Onkyo reciever using a optical digital connection or directly with the HDMI cable ?


Hi

You will have to assign the optical input to the input you are using, so for instance if you have plugged the optical cable into opt 1 on the onkyo reciever and wish to use the DVD input on the onkyo reciever, you need to go into the set of the onkyo to digital assignments or in/out assignments, dependent on the model, and select OPT1 for the DVD input. You can find out how to exactly do this in the onkyo's manual under 'digital assignments' or 'input assignments'.

Reciever says there are headphones plugged in, and there are not!


Possibly a bad connection in the jack or bad solder on the jacks circuit board. First clean the jack with a very little wd40 or similar lubricant then plug in a head phone in and out 5 to 10 times, this should clean the contacts of the swtich in the jack, that signals the micro that headphones are being used. If that doesn't do it take the top off and look at the circuit board for and rings ir cracks in the solder near the jack. Depending on the model could be very easy or fairy difficult.

Good Luck.

Headphones only have left channel on Denon AVR-588 Receiver


Hi peroty,

Two suggestions for you.

1. If you look at the headphone jack connecton do you see one or two black O-rings or black lines on the jack. If you only see one they are Mono headphones and you would only get sound out of the left side. If there are two black lines they are stereo headphones and you should get sound on both the left & right sides.

2. If after checking the headphone jack connection and there are two black lines on it then I would suggest try a different pair of headphones to see if a different set of headphones works fine.

If a different pair of headphones works properly the original headphones may be bad. If neither set of headphones work properly it may be the reciever that may need to be repaired.

I hope it's not the receiver, but let me know if you have questions.

Sound Distortion


somekind of hardware side failure or bad drivers.
I hear sounds from my audio output if i connect my headphones there directly but when I connect it to my speaker system they filter the distortion.
