What is the distance a video signal can be reliably sent before an amplifier is needed to boost the signal?
There are many factors which can affect a video signal, such as the quality of the cable being used, the output characteristics of the video signal, and the horizontal frequency or resolution of the signal. In some cases the signal can be extended for a long distance with very little visible degradation. In other cases the distance must be very short. Some guidelines to use for determining the need for an amplifier are: PC and Mac: 10-15′ — use an Extron RGB interface or DA to increase distance. Sun and SGI: 6-10′ — use an Extron RGB interface or DA to increase distance. Composite video: 100′ (30 m) — use an Extron CVDA 6 MX to increase distance. S-video: 50′ (15 m)– use an Extron SVDA 6 MX to increase distance. It also recommended that any time a signal is split, it should be split with a distribution amplifier. With computer video signals of 48 kHz and above, we recommend the use of a MBC buffer (instead of an MBC Y cable) for the input to an interface. This will assure that the
