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.

The frequency response of the

Component Video Monitor Out signal is

5Hz—60MHz, making it compatible with

HDTV monitors.
