    Setup It’s tempting to just plug in your new AVP and have great sound pour out. Before you do that, take a few minutes to plan out how you want the preamplifier to fit into your audio/video system.

    and attach it to the cable near both ends. This makes it easy to identify. To ensure maximum safety, keep all cables out of high traffic areas (hallways or doorways) and away from equipment that radiates power, including amplifiers, power cords, heaters, etc. If you might expand your audio/video system later, keep these ideas in mind as you plan current cable runs.

    Surround setup Always set up and calibrate your speakers immediately after connecting your preamplifier to your system. You need to set up the speakers to achieve the best, most accurate performance from your preamplifier.
