Re: How to use Interstage VAR-EQ on SA LEII

While i was contracting i never gave them much thought but now after being in house with a cable company and seeing the same amps more once i am seeing that the thermal interstage EQs are doing a good job of stabilizing the levels during temperature changes. Most systems I have contracted in usually had a Trunk Amp with an AGC feeding a series of line extenders. The 1st LE would have just a variable interstage EQ or "manual" the second a thermal, 3rd a manual, 4th Thermal. I have seen SAII and SAIII LEs with AGCs not do as good a job as LEs with Thermal I.S. EQs. If you install a thermal were there is a manual you usually have to lower the Interstage pad by about 4 dB. I will usually pad the input per spec and reduce the interstage pad by 3 or 4. then come back in an hour or the next day to see what its putting out after warming up and adjust the I.S. padding. Just trying to contribute my 2 cents.
