Can you use 2-wire Speakon® cables to connect the A1 amplifier to B1 bass modules?
Yes. Unlike the L1™ Power Stands (Classic, Model I, Model II) there is no sensing circuit that determines the number of B1s attached to a PackLite® so there is no specific need to use the 4-wire Speakon® cables instead of 2-wire Speakon® cables. Note however, that the B1s are supplied with the blue 4-wire cables and these work fine.
