NOTES:
o Make sure that the speaker cords are connected
to the terminals securely. lnsecure connections may
causenot only sound to be interrupted and noise to be
generated but also the cords to be shorted and the
amplifier to break down-
o When listening to a stereo performance with the
speaker system connected to a stereo amplifier,
you will find that the bassis insufficient. the sound is
not spread out and there is no stereo effect if the
cords of one of the speaker system have been plugged
into the wrong polarity terminals.
