check to make sure that the conductors on each loudspeaker are attached the same
on the loudspeaker and the amplifier. If you cannot see any markings or determine
if they are all attached the same, try this simple test:
1. Point the speakers at each other, rather than at the area you want to cover.
2. Play some music with the amplifier or receiver set to Mono.
3. Stand so you are the same distance from each speaker and listen to the richness
of the bass and the loudness of the sound.
4. Turn off the amplifier and reverse the connections on one speaker only.
5. Repeat the listening test with the same setting of the volume controls. If the
current sound has a richer bass and is slightly louder than the previous sound,
the speakers are working together and are "in-phase". Leave the speakers
connected to the amplifier in this configuration. If the current sound is not richer
in bass or louder than the previous sound, turn off the amplifier and reverse the
connections of the wire you moved in step 4.
Verify System Operation and Loudspeaker Coverage
1. Turn the system "On" and play music to the speakers. Set the Volume controls to
a level that allows the speakers to be easily heard over the "noise" in the area.
2. Verify that music is playing through each speaker. If not, trouble shoot the wiring
and make sure each speaker is electrically connected to the amplifier.
3. If you attached your loudspeakers in a stereo mode, verify that they are
connected to the proper channel of the amplifier. To do this, change the balance
of your speakers on your amplifier or receiver so that one channel is at playing
loudly and the other is not. Verify that the speakers are attached to the proper
channel per the layout of the loudspeakers on the plans. If they are not, correct
the wiring on the loudspeaker that is not connected properly. Reset the balance
on the amplifier or receiver so both channels have a similar volume level.
