GFR-700 Owner’s Manual
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.
