Setting Up

Check the connections

Check to be sure all connections are made positive to positive (+ to +) and negative to negative (– to –) (Figure 4). Make sure that no loose strands of wire touch across terminals. Bridged wires can short circuit and damage the amplifier. Tighten any loose connections before you plug in the receiver and turn it on.

Test the speakers

To make sure your speakers operate correctly:

1.Place the speakers less than 6 inches (15 cm) apart, facing each other.

2.Turn on your receiver. Set the receiver to MONO (monophonic), if that is an option on your receiver.

3.Make sure that all special effects (such as surround sound) are turned off.

4.Set the balance control to normal (center position).

5.Play some deep bass passages of music through the speaker.

The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, one of the connections may be reversed, causing the speakers to play out of phase (refer to “Make the connections” on page 6).

To correct the problem, make sure all the wires are connected positive to positive (+ to +) and negative to negative (– to –). Then repeat steps 1 through 5 above to re-test

the speakers.
