Hi, I'm repairing an active summing device that has an BFE DV1175 card in it. I think its a virtual ground kind of summing card, haufe transformers on it. It runds ok with balanced signals but when I put an unbalanced one (bridging the cold to ground) it has like an soft Hi pass filter... the signal on output decreases its level when more I go down the freq of my signal generator. I'm triying to figure if its a normal behabior in that kind of cards or Im doing some mistake and that its not normal at all.
Well... thanks in advance!
