SETTING THE EQUALIZER WARNING THRESHOLD

The EQ trimpot R28 located near jumper J8 is used to set the threshold of the cable equalizer warning.
The equalizer warning is factory set to 125 meters of Belden 1684 cable, but may be adjusted for other
cable types or cable lengths. To adjust the cable equalizer warning threshold, connect a signal to the
input of the DA using the required length of cable. Adjust the trimpot slowly until the Equalizer warning
LED comes on. You can verify that the equalizer warning is operating correctly by removing a few meters
of cable from the input. The LED should go off.
