adjustment changes the level and peaking of the output signal
to compensate for capacitance caused by up to 1000 feet
(300 meters) of Extron RG6 cable.
Use a small, flat-blade screwdriver to rotate this control.
View the display and select the setting that gives the sharpest
picture. For a more precise setting you can use an oscilloscope
or a waveform monitor connected to the far end of the output
cable, and adjust the equalization so that the color burst ranges
between -20 IRE and +20 IRE.
The Equalize control is a potentiometer with a soft
mechanical stop at the high and the low end. If you
have reached the high or low end of the adjustment, the
potentiometer makes a clicking sound as you turn it, and
no change is apparent on the display.

-6 dB to +6 dB. Select the setting that gives the
best picture brightness.
You can judge the adjustment visually by
looking at the display. For a more precise
setting, you can use an oscilloscope or a
waveform monitor connected to the far
end of the output cable, and adjust the
gain so that the level at the waveform
monitor is 100 IRE.
