NEW PRODUCT BULLETIN

Preout Terminals for All Channels

Preout terminals are provided for the two main, two rear, center, rear center and subwoofer channels so these outputs can be fed to one or more additional amplifiers for those desiring even higher levels of power.

HDTV Compatible Component Video Out

The frequency response of the Component Video Monitor Out signal is 5Hz—60MHz, making it compatible with HDTV monitors.

Front Panel Video Aux Input Terminals

Front Panel Video Aux Input Terminals includes S-video and optical digital input terminals for connecting game machines, digital equipment, and so on.

Fixed and Assignable Terminals

Yamaha offers terminals that can be

either independently assigned to sources or defaulted to fixed settings.
