■ Connections
Before making connection, make sure that the
amplifier is switched off.
• Connect the screw-type terminals at the rear of the
speakers to the speaker terminals on the amplifier with
a supplied speaker cable.
• Connect the + terminals on the amplifier and on the
speakers using one side of the cable. Connect the –
terminals on both components using the other side of
the cable.
• Connect one speaker to the left (L) terminals of your
amplifier, and another speaker to the right (R) terminals,
making sure not to reverse the polarity (+, –). If one
speaker is connected with reversed polarity, the sound
will be unnatural and lack bass.
How to connect
1
Loosen the knob.
2
Twist the exposed wires of the cable together.
3
Insert the bare wire into the hole.
4
Tighten the knob and secure the cable.
Test the firmness of the connection by pulling the
cable lightly at the terminal.
• Do not let the bare speaker wires touch each other as
this could damage the speaker and/or the amplifier.
• Do not insert the insulation coating into the hole.
The sound may not be produced.
