speaker cones will be moving in, while others move out. This will cause indistinct or confusing imaging, and muddled and cloudy sounds. To avoid incorrect phasing or polarity, be sure to use wire that has distinct markings, colors, stripes, wording, or grooves on each side of the speaker cable. When making connections to the amp and speakers, follow a consistent pattern of using one side of the wire to the red terminals and the other side to the black. When using cable with markings on one side only, standard convention is to consider the marked side of the wire as the red, or positive (+) connection, and the
Next loosen the knobs of the amplifier’s speaker output terminals far enough so that they pass through hole is revealed. Follow the proper connection instruction for your system with regard to which terminals are used. Once the connections are made, twist the cap back so that the connection is secured but do not over tighten or use tools, as this may break the delicate wire strands and decrease system performance.
If you are using spade lugs, connect them to the speaker wire using the manufacturer’s instructions, and then loosen the caps on the speaker terminals. Place lugs between the plastic cap and the back of the terminal. Be sure to observe proper polarity. Use your fingers to tighten to obtain a positive contact.
When using banana plugs, connections may be made by inserting the jack affixed to your speaker wire into the hole provided on the rear of the colored screw caps on the binding posts. Before using banana
Run the cables to speaker locations. Do not coil any excess cable, as this may become an inductor that creates frequency response variations in your system. Lastly, connect the wires to the speakers, again being aware of proper polarity. Remember to connect the negative, or black wire, to the matching terminal on the speaker. The positive or red wire should be connected to the matching terminal on the speaker.
Note: While most speaker manufacturers follow industry convention of using red terminals for positive connections and black terminals for negative, some manufacturers may vary from this configuration. To ensure proper phase connections, and optimal performance, consult the identification plate on our speaker terminals, or the speaker’s manual to verify polarity. Contact the speaker’s manufacturer if you do not know the polarity of your speakers.
Making rear panel connections
When connecting the amplifier to your source equipment, match the output channel designations on the rear of your source equipment to the input jacks on the rear panel of your amplifier that have the same channel name. Correct polarity connections are important to maintain proper speaker phasing. When making connections to the amp and speakers, follow a consistent pattern of using one side of the wire to the red terminals and the other side to the black terminals.
