feet of 24 AWG cable should give a reading of approximately 26
ohms (52 ohms if you are measuring at one end with the opposite ca-
ble ends shorted).

The Audio-Video Hub must be kept away from sources of radio-
frequency or electromagnetic radiation :
a)
5" from power lines of 2 kVA or less.
b)
12" from fluorescent lighting & power lines between 2 &
5 kVA.
c)
36" from power lines greater than 5 kVA.
d)
40" from transformers & motors.
Best performances will be achieved using home-run cable. Do not
use flat cable (i.e., cable that is not twisted), even for patching with
short runs. Flat cable acts as an antenna and will pick up nearby ra-
dio-frequency interference.

Identify the pin configuration of both the video balun and the Audio-
Video Hub. For example, when using the VideoEase Stereo Audio-
Video Balun (500001), the modular cable must use straight through
polarity.
