Extron electronic CSVEQ 100 D Gain adjustment control, Equalization EQ adjustment control

WThe two power cord wires must be kept separate while the power supply is plugged in. Remove the power before wiring.

NDo not tin the power supply leads before installing in the direct insertion connector. Tinned wires are not as secure in the connectors and could be pulled out.

Gain adjustment control

The gain control adjusts picture brightness by compensating for signal amplitude loss caused by cable resistance. To adjust the output gain, view the display while using a small, flat-blade screwdriver to rotate the potentiometer. This control produces a gain adjustment ranging from -1 dB to + 3 dB (video and luma of S-video) and from 0 dB to +10 dB (chroma of S-video). Select the setting that gives the best picture brightness.

NThe gain control is a potentiometer with a mechanical stop at the high and the low end. After you have reached the high or low end of the adjustment, no change is apparent on the display. The default is unity (the dot position)

You can judge the adjustment visually by viewing the display. For a more precise setting 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.

Equalization (EQ) adjustment control

The equalization control adjusts the output level and peaking to get a sharp picture. This adjustment changes the level and peaking of the output signal to compensate for capacitance caused by up to 1000 feet (300 meters) of Extron MHR cable.

This control produces an equalization adjustment ranging from 0 dB to + 7 dB (video and luma of S-video).
