To create a hookup to the receiver if it does not have a "monitor" output. Don't be confused by consumer goods like this. That is, for special applications or needs you use the folk that know how to fix this issue.
RECEIVER HAS INPUT IN FRONT FOR HPHONES, BUT WHEN U PLUG THEM IN THEY KILL SPEAKERS. I AM HARD OF HEARING AND DO NOT WANT TO IRRITATE OTHERS WITH THE VOLUME, SO I NEED THE SPEAKERS AND THE HPHONE TO BE ACTIVE AT THE SAME TIME! TV IS SAMSUNG HLR5668WX/XAA AND DOES NOT SUPPORT HPHONES. HOW OR CAN I GET AROUND THE HPHONE JACK KILLING THE SPEAKERS??? THANX
