5. 5.1 CHANNEL AUDIO OUTPUT
jacks-These jacks are used for connecting to 5.1 channel ready
receivers/amplifiers. The label on each jack specifies which speaker in the surround sound system the
output signal from the labeled jack is sent to: FL-front left, FR-front right, SL-surround left, SR-surround
right, CEN-center, SW-subwoofer. The ML jack is the same as the FL jack and is used as the main left output
in a stereo system. The MR jack is the same as the FR jack and is used as the main right output in a stereo system.
6.COMPONENT VIDEO OUTPUT
- These jacks output VIDEO to a TV monitor via COMPONENT VIDEO cables.
COMPONENT VIDEO outputs the different color signals (U/Pb and V/Pr) and luminance signal (Y) separately
for high-fidelity in reproducing colors. The description of the component video output connectors may differ
depending on the TV set or monitor i.e. Pr/Pb/Y or Cr/Cb/Y or R-Y/B-Y/Y. Component video cables only transmit
the video signal, separate cables are needed for audio signals. Please refer to the operating instructions of the
TV set or monitor for details.
7.COAXIAL OUTPUT
- This digital output is for connecting devices with a COAXIAL cable.
8.VIDEO (RCA) and S-VIDEO OUT
jacks - These jacks output video to a display device (TV, TFT, etc.). The
VIDEO jack outputs video using an RCA video cable. The S-VIDEO jack uses an S-VIDEO cable. S-VIDEO
provides better color separation and better resolution by separating the color and picture signals of a
composite-video signal.
9.OPTICAL OUTPUT
- This digital out is for connecting devices with an OPTICAL cable. Please make sure to
remove the protective cover from this jack prior to connecting an OPTICAL cable. When not using this input,
