4.0 OPERATING THE UNITS
The Gain and Equalization controls on the 1381R Receiver should be adjusted to optimize the video signal for the Cat 5 cable length. Low Gain and Equalization settings are usually best for shorter cable runs but receivers located at the end of cable runs near the limit of specified range may benefit from higher Equalization and/or Gain adjustments. It is best to make adjustments after permanent source and video display equipment is installed. EQ and Gain settings are retained by the Receiver even when power is removed.
4.1 ADJUSTING EQUALIZATION
Locate the EQ (Equalization) and GAIN adjustments on the side of the 1381R Receiver. The EQ control is at the top of the left side, and the Gain Control is just below it.
Symptoms: On long cable runs, the high frequency detail can be compromized, which appears as a “soft” or “smeared” picture. The effect is most evident in text and other hard, high contrast edges.
Adjust the EQ to sharpen the image. While viewing an image on a display connected to the 1381R Receiver, insert a small screwdriver into the EQ adjustment on the side panel of the 1381R. Turn the screwdriver gently until the image is optimal.
4.2 ADJUSTING GAIN
If the image is too dark or too bright, insert the screwdriver into the Gain adjustment and rotate until the brightness of the image is optimal. When using long Cat 5 cables, you may notice an increase in video noise (sometimes called “snow”) in the picture at higher gain settings.
