I have a Sony TC-248D quad 8-track player. When I play a stereo 8-track on it, it sends the left channel out on both the left front and rear ports and the right channel out on both the right front and rear ports. Why doesn't it just send it out the front ports and leave the rear ports alone? If I'm playing stereo, I just want to hear two channels from the front. Is this standard? It's damn annoying.
