switch the speaker in question
with one of the other speakers

has followed the speaker or has
remained in the same channel.
If the problem is in the same
channel, the source of the prob-
lem is most likely with your
receiver or amplifier, and you
should consult the owner’s man-
ual for that product for further
information. If the problem has
followed the speaker, consult
your dealer for further
assistance or, if that is not pos-
sible, visit www.jbl.com.
