    1.2 Rear Panel Inputs & Outputs - System Connections Like the front panel, the GTP-830’s rear panel is carefully arranged to make hookup, configuration, and use as simple as possible. However, the GTP-830’s extraordinary capabilities take some study to use most effectively. We strongly suggest that you read this section of the manual before beginning to hook up your system.

Even when the GTP-830 is correctly set-up, it may sometimes be desirable to make minor adjustments to suit the material you are listening to. Pressing the bal button allows for direct adjustment of Center, Surround, and Subwoofer levels.

  • Page 29: Installing/Connecting The Gtp-830

    Keep the GTP-830 (and other audio/video components) away from moisture and out of direct sunlight. Bear in mind that the GTP-830’s rear panel is the central connecting point for almost every compo- nent in your audio/video system. Leave sufficient room behind the rear panel to accommodate cables, antenna leads, power cords, etc.
  • Page 30 GTP-830 to the specific speaker arrangement and dimensions of your system. The procedures described in this section demonstrate how to use the GTP-830’s on screen display to enter this information. Once complete, the GTP-830 stores this information so that these tasks need only be repeated if speakers are changed or substantially repositioned.

The GTP-830 can delay the center channel output up to 5 milliseconds and thus compensates for cen- ter channel speakers that are up to 5 feet (1.5 m) closer to the listening position than the front left and right speakers.
