Have a Optimod 9100 up at the AM tower feeding off the Marti... Heil Mic's into the board... No processing from Mic to Board, or board to Marti send.... I have an old Sound Tech gate limiter:leveler:compressor available to me and have considered dbx 286's for the mics and if I can afford it the ART tubed compressor limiter to level things together before going to the Marti and on to the tower.... What do you think... Love to hear it... I want clean crisp punchy AM that we grew up to.... "Skip"
