Connections

This speaker does not include speaker cables used for connecting 

to an amplifier.

Connecting the cables

1

Switch off the power to your amplifier.

2

Connect the speaker cables to the input terminals on the 

back of the speaker. For input terminal polarity, red is 

positive (+) and black is negative (–).

Loosen the knobs on the input terminals and insert the speaker 

cable wires into each of the terminal post holes, then tighten the 

knobs.

3

Connect the other ends of the cables to the amp's 

speaker 

output terminals (for more details, refer to your amp 

instruction manual).

• You can also connect the speaker’s terminals with a banana 

plug. 

• When using a banana plug, first remove the caps covering the 

speaker terminal.

• After connecting the plugs, pull lightly on the cables to make 

sure that the ends of the cables are securely connected to the 

terminals. Poor connections can create noise and 

interruptions in the sound.

• If the cables’ wires happen to be pushed out of the terminals, 

allowing the wires to come into contact with each other, it 

places an excessive additional load on the amp. This may 

cause the amp to stop functioning, and may even damage the 

amp.

• When using a set of speakers connected to an amplifier, you 

won’t be able to obtain the normal stereo effect if the polarity 

(

+

, 

–

) of one of the speakers (left or right) is reversed.

. To prevent the risk of electric shock when 

connecting or disconnecting the speaker cables, 

disconnect the power cord before touching any 

uninsulated parts.
