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.
