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. | Yes.

No. Only 4-wire Speakon® cables are to be used with the A1 amplifier. The additional 2 wires (<nowiki>+</nowiki>2 and -2) in the connector are used for sensing purposes. Upon connection, the signal is automatically adjusted (EQ and level) for 0, 1 or 2 B1 bass modules. | No. Only 4-wire Speakon® cables are to be used with the A1 amplifier.

If you plug in a 4-wire Speakon® cable to the Bass Module Out connector with music playing through, you will clearly hear the L1™ Model II system mute for a moment. If you are using an incorrect cable, such as a 2-wire Speakon® cable, the momentary muting will not occur. | If you plug in a 4-wire Speakon® cable to the Bass Module Out connector with music playing through, you will clearly hear the L1™ Model II system mute for a moment.

To prevent damage, the amplifier is protected against overheating, short-circuits and over-current conditions. The power LED will turn red when there is a problem and will return to normal operating mode when the fault condition has been removed. If used with a power stand and two B1s, the bass level would drop 6dB upon shutdown. | ||
