    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. If you haven’t already done so, ask yourself the following questions: What source components do I want to connect to my preamplifier? (CD, VCR, etc.)

    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.

  • Page 18: Making The Connection

    Making the connection Take a look at the back panel of the AVP. You will notice that the RCA-type audio input and output connectors are identified by colors. Red for right channel and white for the left channel audio. Composite video input and output connectors are identified by yellow.

  • Page 21: 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. This is important because the preamplifier needs to “know” your speaker configuration to control your current system. Any time you change your speaker configuration, you should perform setup and then calibration on your preamplifier.

  • Page 24: Speaker Calibration

    Speaker calibration Always calibrate your speakers after you have performed setup. Surround calibration is different from adjusting balance levels. When you calibrate, you equalize volume levels on all channels with a final goal of ensuring that the volume is the same on each one. When you adjust balance, you turn the volume up or down on specific channels because the sound you are hearing seems either too loud or too soft.
