Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted from
a source to a destination.
 Signal cables — Use only the best quality cables to avoid interference
and degraded signal quality and elevated noise levels.
 Sockets and connectors of the sources and destinations — Use only the
highest quality, since "zero ohm" connection resistance is the target.
Connectors should also match the required impedance (75 ohm in
video) to minimize return loss.
 Amplifying circuitry — Must have quality performance when the
desired end result is high linearity, low distortion, and low noise.
 Distance between sources and destinations — Plays a major role in the
final result. For long distances (over 15 meters) between sources and
destinations, special measures should be taken to avoid high frequency
cable losses. These measures include using higher quality cables and/or
adding line cable equalizing amplifiers.
 Interference from neighboring electrical appliances — These can have
an adverse affect on signal quality. Balanced audio lines are less prone
to interference, but unbalanced audio should be installed away from
any main power lines, electric motors, transmitters, etc. even when the
cables are shielded.
CAUTION!
Only an authorized Sierra Video Systems technician can service the switchers.
Any user who makes changes or modifications to the unit without the expressed
approval of the manufacturer will void the warranty
Use the proper AC voltage to supply power to the switcher.
Use only the recommended interconnect cables to connect the switcher to other
frames.
