Spade Connector: (Figure 10)

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 con-
nector in to 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. 
When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on 
the binding post are tighten down completely. Insert the banana jacks into the caps of the binding post, be 
sure that the banana jack is inserted securely to avoid the risk of it popping out.

Mono Bridge Connections:

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 pos-
itive output terminal for the negative connection and the channel one positive output terminal for the positive 
connection.

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 plugs or bare wire end cables. Major speaker manufacturers have been using Speakon connectors on their products for years, 
so chances are you are ready to use the Speakon connection. With Speakon connectors, you can connect straight from the amplifier 
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.

Bare Wire Connections:  (Figure 9)

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 1/2” (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.  

Typical speaker output using bare wire. Insert 
bare wire into the binding post and tighten.
