The Naim BP1 Spade Connector attaches to the 4mm speaker cable socket of the Ovator S-400 and S-600 to create a binding post for the use of speaker cabling with spade connectors. The Naim BP1 Spade Connector creates a firm, high-pressure contact which is further stabilised by a retaining screw. The Naim BP1 Spade Connector 6mm binding posts accommodates most sizes of spade connector. For especially large spade connectors, different size spacers can be incorporated to offset the two connections, ensuring that the contacts are secure and completely isolated from each other.
