16. Headphones: accepts a stereo 1/4 inch plug for stereo headphones. The signal present at the
Headphones jack is controlled by the Headphone controls switches and level on the front panel. For
more information, see Controls and Operations page 22 and Output and Monitor, page 13.
Some General Notes on Installation
There are a few other things to be aware of when you are installing and integrating the SE-800. Please make
sure you have read the Warnings and Precautions section on page 3.
The SE-800 sends and receives both analog and digital signals. Digital signals are carried through the DV
and SDI cables; all the rest (except the GPI, RS-232 connections) are analog. One of the beauties of digital
is that most of the cautions described below, regarding cable lengths, impedance, crossing power cords, and
adaptors, are not an issue. The cautions below, with the exception of physical damage, apply only to cables
carrying analog video or audio.
It is quite possible these days to buy whatever cable length and connector you need for your set up. Not so
long ago, they had to be assembled individually with wire strippers and solder, but now you can easily find
them in most electronics and video supply stores. We strongly recommend you use analog video and audio
cables that are roughly the right length to connect between components. The longer the cable, the more
noise and deterioration of the video signal can be introduced. We strongly recommend that you check the
integrity of each analog cable before installation by using a continuity tester (available from most electronic
and video supply stores). Cables can go bad over time, with use, by someone walking on them, carts rolling
over them, or even for no apparently good reason. It will happen eventually. Have a continuity tester handy
and save yourself some troubleshooting headaches.
Make sure you don’t run video/audio cables and power lines together, on top of each other, or across each
other. This is another good way to introduce noise and signal degradation.
Cable connectors will eventually become dirty. The dirt can cause a bad connection or introduce noise in the
signal. Get some electrical contacts cleaning products, such as those made by Caig Labs (www.caig.com),
and use them regularly to avoid problems.
Use adaptors if you must, but keep in mind that each connector is one more accident waiting to happen, one
more place the signal can be degraded or broken.
Finally, for some interesting and entertaining examples of how to connect and integrate the SE-800 into a
variety of set ups, take a look at the brief Quick Start section and the more in depth explanations in Sample
Applications on page 15.
