© Active Hyper-Bass circuit
Generally, since low-frequency sound is not reproduced
satisfactorily by small speakers, a bass-boost circuit is
used to reinforce low-frequency sound. However, if the
volume is turned up with bass-boost reinforcement, low-
frequency sound is easily saturated which
results in
distortion. As shown in the diagram, the Active Hyper-
Bass circuit incorporates a control circuit in which the
cut-off frequency of low-frequency sound is varied in
the bass-boost
circuit, with the cut-off frequency
controlled by instructions from a level identification
circuit. With these circuits, when the volume increases,
low-frequencies are sharply attenuated, which prevents
distortion caused by the saturation of low frequencies.

®@ Do not place the loop antenna on a metal desk or near a
TV or personal computer.
@ Installing an outdoor antenna requires experience; we
recommend that you consult an audio dealer.
@ Install the antenna cord away from the power and
speaker cords as these could generate noise. Do not
install the loop antenna so that it touches the rear of the
