RS-232C
The RS-232C port is to be used in conjunction with
an external controller to control the operation of
the SR7500 by using an external device.
The RS-232C port may also be used in the future
to update the operating software of the SR7500 so
that it will be able to support new digital audio
formats and the like as they are introduced.

COMPONENT VIDEO INPUT/OUTPUT
If your DVD player or other device has component
video connectors, be sure to connect them to these
component video connectors on the SR7500. The
SR7500 has 4 component video input connectors
to obtain the color information (Y, C
B
, C
R
) directly
from the recorded DVD signal or other video
component and one component video output
connector to output it directly into the matrix
decoder of the display device.
By sending the pure DVD component video signal
directly, the DVD signal forgoes the extra
processing that normally would degrade the
image. The result is vastly increased image
quality, with incredibly life like colors and crisp
detail.
r
FLASHER IN (Flasher input terminal)
These terminals are to control the unit from each
zone. Connect the control signal from a Keypad,
etc.
