3.1 Connecting the loudspeakers

The LS-77 is fitted with shrouded binding posts prepared for bi-wiring that are standard in high end audio. However, we do not normally recommended their use. They are provided to allow users to easily integrate our speakers into an existing system already fitted with cables prepared for such connections.

AMR's preferred connection method is the professional Neutrik Speakon connector. This provides a sonically vastly superior and more reliable method of connection, due to the connector’s gold contacts, gastight construction and special locking, high-pressure contact arrangement.

AMR's own speaker cables are equipped with Speakon connectors, as are AMR's amplifiers thus guaranteeing the highest performance and most reliable method of speaker connection available.

3.1.1 Using AMR's OptiLink Speakon® Cable

When using AMR's Speakon® equipped OptiLink loudspeaker cables, you simply plug the Speakon® connector into the Speakon® socket marked “IN” and then twist the whole connector clockwise to lock the connector. This establishes a full bi-wired connection with the correct polarity and ensures the connection is maximally tight and corrosion free all in one go.

To disconnect the Speakon® cable you need to pull back the latch and twist the connector counterclockwise. Then you can simply pull out the plug.
