3. SPEAKER TERMINALS
Note: When using a banana plug, make sure the speaker terminals are completely tightened before inserting the plug.
Connect the wires from your left channel loudspeaker to the left positive and negative terminals and the wires from the right channel loudspeaker to the right positive and negative terminals.
In each case, the red terminal is the positive output and the black terminal is the negative output.
Care should be taken to ensure no stray strands of wire short the speaker outputs together. Please ensure that the loudspeaker terminals have been tightened completely to provide a good electrical connection.
It is possible for the sound quality to be affected if the screw terminals are loose.
