Important points in adjusting cut-off frequencies
• If the subwoofer is installed in the rear tray, setting a high cut-off frequency of L.P.F. of the
subwoofer separates the bass and gives the listener the feeling that the bass is coming from behind.
The L.P.F. of the subwoofer is recommended to be set at 100 Hz or below.
• Speakers used for mid and high-ranges are generally constructed to handle a limited level of input
compared to low range speakers. If the cut-off frequency of H.P.F. is set lower than necessary,
strong bass signals can reach the speaker and may damage it.
Important points in adjusting the level
• The low band, because of its sound frequency characteristics, incorporates the basic frequencies of
many musical instruments. It is recommended that the level adjustment of the low band be made
first, and then the level adjustment of the mid, high, and subwoofer be made in that order.
