Connecting Video Sources

There are two types of plugs used for video signals on the SE-500: BNC, and S-video.
BNC connectors look like this on the cable end. The connector slides over the connector on
the SE-500 and is locked in place with a push in and clockwise turn. The big virtue of these
connectors, which are the standard for almost all professional video applications, is that
BNC
they lock in place and cannot be accidentally dislodged.
S-video plugs (also known as Y/C) have 4 tiny pins in them, which carry a separated Y
(luminance) and C (chroma) video signal and provide a much better quality video signal
than composite. These plugs have a tiny bar in them to assure correct alignment in the
socket. They need to be pressed firmly in place, but very carefully, as the little pins can

bend easily. Align plug and socket and push straight in, firmly.

Connecting Audio Sources

The SE-500 uses 2 kinds of plugs for audio connections: RCA and 1/4 inch jack plugs. There are lots of
different names for these plugs. Fortunately for us all, they are not easily confused in the size and shape
departments, so we'll show you some pictures.
RCA plugs (also sometimes known as phono plugs, cinch, or tulips) are used
for line level audio, such as the connections between a CD player and amp.
The SE-500 uses these in stereo pairs, white for left and red for right, at the
audio input and output sections.
RCA
1/4 inch jack plugs got their name, some say, because they used to be used to
manually patch together phone lines in the old central switchboard days. They
come in mono and stereo configurations: the mono has one dark band around
the plug, the stereo has two. The SE-500 uses a mono plug on MIC CH1 and mono
plugs for MIC CH2. ¼ Mono Jack
If you need to use balanced audio inputs or outputs, for low impedance
microphones or connections with other professional audio gear, you need to use
an impedance matching device to convert low to high impedance (and/or vice
versa). For example Datavideo BAC-03 (on page 44 )
¼ Stereo Jack

Outputs and Monitoring

Your particular set up and application for the SE-500 will determine what video and audio devices you
connect to the outputs. Take a look at the Sample Applications, page 29 for some examples. While all the
outputs of the SE-500 are very high quality, keep in mind that the video quality of the various formats, in
descending order, goes like this: Y.U.V. (analog component), Y/C (S-video), and Composite. Audio outputs
are all line level, suitable for connecting to an amp, VCR, or video projector (for example).
