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 3.
5. Check the phase between each speaker in the area by following the procedures
for two-speaker stereo mode. Remember to change the phase on both sides of the
speaker when you perform step 4 of that procedure.
In two-speaker stereo mode or checking phase between speakers
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. Verify that each speaker is 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 each speaker or each
side of the speaker is attached to the proper channel of the amplifier. 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.
4. If you used a volume control between the amplifier and the speakers, verify that
it is controlling the volume of the loudspeakers in its zone. Repeat this for every
volume control in the system. If it is not, correct the wiring.
5. Point the loudspeakers per the layout and verify that the sound is even and
consistent throughout the area.
