there aren't many rca hookups in the back. I have a sx-218 k pioneer reciever. I can see the graphics since they show but I can t hear any difference in tones. How do I set it up for the best performance. not sure what to hook it up to there are cd/dvd jacks, tape jacks, and tv/sat jacks which are in use, then digital . The equalizer brand is a Techincal Pro Brand and is 20 band.
