BARE WIRE CONNECTIONS: (Figure 10)
When connecting your speakers to the amplifier using bare wire, unscrew the red and black caps on the binding
post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire insulation ½”
(13mm). Insert the bare wire into the hole that was reveled by unscrewing the binding post cap. After inserting the
wire into the binding post hole, screw the binding post cap down on the wire. To reduce the risk of shock or
damage to your amplifier, be sure that the wire connected to one binding post does not come in contact with that
of another.
SPADE CONNECTOR: (Figure 11)
When connecting your speakers to the amplifier using spade connector, unscrew the red and black caps on the
binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade connector
into the binding post and tighten the caps down on the spade connector. To reduce the risk of shock or damage to
your amplifier, be sure that the wire connected to one binding post does not come in contact with that of another.
MONO BRIDGE CONNECTIONS: (Figure 12)
Mono bridge operation connections will follow the above descriptions, however, when operating in mono bridge
operation the speaker connections will run between the two positive (red) leads. Use channel two positive output
terminal for the negative connection and the channel one positive output terminal for the positive connection.
Typical speaker output using bare wire.
Insert bare wire into the binding post and tighten.
Typical speaker output using spade connectors.
Insert bare wire into the binding post and tighten.

STEREO CONNECTIONS USING THE NEUTRIK SPEAKON OUTPUT CONNECTORS:
Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and force amp users to
terminate their speaker cables with spade lugs or bare wire ends. This is not advantageous to most users that want
to reconfigure their systems or quickly change out an amp. The Neutrik Speakon connector provides the most
convenient solution to this problem, eliminating the need for spade lugs or bare wire end cables. Major speaker
manufacturers have been using Speakon connectors on their products for years, so chances you are ready to use
the Speakon connection. With Speakon connectors, you can connect straight from the amp to the speaker. The
Speakon connector used on this amplifier meets all known safety regulations. Once wired correctly, the connector
cannot be plugged in backwards, causing the type of inverted polarity situations that have become common with
banana hookups. This connection will provide a safe, secure and reliable method of connecting your speakers to
your new amplifier. You can purchase the Speakon NL4FC connectors from your local audio dealer.
