Connecting your speakers to your receiver/amplifier

Speaker cord consists of two insulated wires. The wire marked with a stripe or rib is used for the positive (+) red terminal connection. The plain wire is used for the negative (–) black terminal connection. Strip approximately ½ inch (1.3 cm) of insulation from the ends of both wires (Figure 6). Then, twist the ends of each wire so there are no loose strands.

CAUTION: Before making any connections, turn off your receiver/amplifier an d un plug it from the AC power outlet.

(+) Terminal

1. At the back of your speaker (Figure 6), unscrew the hex knobs on the terminal posts until

you can see the small hole going through each post.

2. Insert the marked (+) wire into the red (+) terminal. Insert the plain (–) wire into the black

(–) terminal. Tighten the knobs to secure the wires.

3. Check the speaker connections carefully. Make sure no loose strands of wire touch

across terminals creating a short circuit that can damage an amplifier or receiver.

Note: After making the connections, any bare lengths of speaker wire can be affected by exposure to the outdoor environment. To protect the speaker wires, apply a thin coating of silicone caulking material, such as RTV adhesive, to any bare sections of speaker wire.

The Bose® 151® SE Environmental Speakers

Connect the speaker on the left side of the listening area to the left amplifier channel (Figure 7). Attach the marked wire to the red (+) terminal. Attach the plain wire to the black (–) terminal.

Connect the speaker on the right side of th e listen ing area to the right amplifier channel.

Testing the connections

Set the balance control on your receiver or amplifier to nor mal (centered) and play some deep bass passages of music through the speakers. Verify that the sound seems to come from a point between the two speakers, and that the bass is full and natural. If not, check your connections again; they may be reversed, causing the speakers to play out of phase. Make sure all the wires are connected positive to positive (+ to +) and negative to negative (– to –).

Troubleshooting

Problem What to do

Neither speaker plays

Bass or treble is weak

Only one speaker plays

One speaker still does not play

1. Check the settings on your receiver/amplifier. Refer to its owner’s guide for instructions.

2. If your speakers are connected to the “B” output, check that the “B” output is selected.

Check the tonal balance setting on your receiver or amplifier.

1. Make sure the balance control is centered on your receiver/amplifier.

2. Check the wires connected to the speaker that does not play. Make sure the wires are in good

condition and are firmly connected.

1. Disconnect the working speaker from the receiver or amplifier.

2. Switch the cord of the faulty speaker from its original receiver or amplifier jacks to the other set of

jacks (the working speaker was originally attached to those jacks). If the speaker now works, the problem is your receiver or amplifier. Reconnect the speakers to a working unit. If the speaker still does not work, continue.

3. Remove the cord from the working speaker and connect it to the faulty speaker . If the speaker now works, the original speaker cord is bad. If the speaker still does not work, the speaker is bad.

4. If trouble persists, contact your authorized Bose dealer, who will arrange for service. Or, contact Bose Customer Service. Refer to the list of phone numbers and addresses included in the carton.
