Selecting Surround Modes

If source components are the main course in your home entertainment center, then Surround modes provide the special sauce. Surround modes process incoming audio signals and distribute them to your speakers—with each mode configured to bring out the unique flavor of your source material and send just the right mix to suit your personal taste and spe- cific speaker configuration.

•To set the default Surround mode for each input, see page 33.

•To select Surround modes on the fly, press the Mode button on the remote control or the Sur Mode button on the front panel.
