JUst got my my alembic f-1x crest ca9 and schroeder 210212l in the mail I pluged everything in and everything turned on so I assume it has enough power. I conneceted the full range output of the alembic to the input A on the crest, I put the crest on bridge and conneced my banana plugs to the binding middle binding posts. Then I connected the other end (speakon) to the schroeder. I pluged my bass in and turned all the volumes up and there was no sound, not even a little hummm. I noticed the signal indicator on the crest was not turning on so I connected another bass, still no sound. Help!
