I have 2 subs. The SVS is connected to in/output 1 and the Von Schweikert S/3 sub is on in/output 2. Which is left engine and what is right? Is in/output 1 the Left channel and 2 the right? Also I need to set each sub differently so I do not want couple mode, how do I get the Left and Right engine lights to be active at the same time without being in couple mode? I need to cut 12 db's at 40hz on the PB2 and 10db's at 40hz on the S/3 with a 1/3 octave bandwidth. Thanks for your help. Steve BTW I have Sonnie Parkers site printed out and in book form.
