total impedance of 4 ohms. Never connect loudspeakers whose total combined impedance is lower than the amplifier’s recommended minimum load impedance. Do not use the loop-out connection to connect other types of loudspeaker, especially when their impedance is not known, as permanent damage could result!

Please take care if XLRs, binding posts, or other dual connector systems, are used at the amplifier end of the loudspeaker cables (jack plugs/sockets should not be used) where there is a possibility of the cables being reversed. It is highly recommended that Neutrik Speakon or other heavy duty non-reversible connectors are used.

Cable Recommendations

Heavy duty loudspeaker cable should always be used, with a minimum wire size of 12 gauge (1.5mm²), and preferably 10 gauge (2.5mm²) for longer runs, keeping the run as short as possible. This helps to avoid wasting amplifier power in the resistance of the cable. High cable resistance also lowers the damping factor of the amplifier which affects its ability to control loudspeaker cone movement.

Losses due to undersized cable and long runs are clearly illustrated in the table below. Please use this table to determine the most suitable cable size and maximum run for your particular application.
