The ES-201 provides a loop-thru input and four isolated outputs, all accessible via BNC connectors. An independent screwdriver-adjustable Gain and Equalization control for each output are provided on the front of the case. Up to 1000 feet of cable may be compensated by adjusting the EQ trimmer. The Gain control provides an overall signal level adjustment of - 2 to +3 db. When the input is not looped thru to other equipment, a 75 ohm terminator should be used on the free input connector. Unused outputs need not be terminated.
