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 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.
