Connecting the speaker wire to the receiver or amplifier
1. Connect the speakers on the left side of the listening area to the left channel of your
receiver or amplifier (Figure 17).
a. Attach the marked wire to the red (+) terminal.
b. Attach the plain wire to the black (–) terminal.
2. Connect the speaker on the right side of the listening area to the right channel of your
receiver or amplifier, following the same procedure above (Figure 17).

Note: If your 251
speakers are being connected as a secondary set of speakers to your
receiver or amplifier, be sure to make the appropriate connections to the "B" channel.
Checking the connections
Check the speaker connections carefully. Make sure no loose strands of wire touch across
terminals. This could create short circuits that can damage an amplifier or receiver.
Tighten any loose connections before you plug in the receiver or amplifier.
Testing the connections
To make sure your speakers operate correctly, follow these steps:
1. Set the balance control on your receiver or amplifier to normal (centered).
2. Play some deep bass passages of music through the speakers.
The sound should seem to come from a point between the two speakers. The bass should
be full and natural. If not, your connections may be reversed, causing the speakers to play
out of phase. Refer to "Making the connections" on page 9. To correct the problem, make
sure all the wires are connected positive to positive (+ to +) and negative to negative (– to –).
Then repeat steps 1 and 2 to re-test the speakers.
