• Be sure to observe the amplifier’s rated load impedance (see
“Specifications”), particularly when connecting speakers in parallel.
Connecting an impedance load outside the amplifier’s rated range can
damage the amplifier.
• When using a high-impedance speaker connection, make sure the audio
signal is passed through an 80 Hz or above high-pass filter before being
input to the speakers.
• When connecting the speakers with high impedance, be sure that the
total rated input capacity of the speakers does not exceed the output
power of the amplifier.
• Do not swing the speaker by its carrying band.
• Do not place the speaker face down with the grille attached, as
deformation of the grille may result.
• When placing the speaker face down, always place it on a flat and
smooth surface.
• Do not touch the speaker driver unit.
● Protective circuit
This speaker system has an internal protection circuit that shuts off the
speaker unit when an excessive input signal is applied. If the speaker unit
emits no sound, reduce the volume level of the amplifier immediately. The
sound will return automatically in several seconds.
