Output signals with these frequencies

Slope off

20 Hz

10 kHz

H.P.F. cutoff frequency

L.P.F. cutoff frequency

The H.P.F. setting cannot be the same as or exceed the L.P.F. setting for that channel.

The crossover network is a filter that divides specific frequency bands.

The high pass filter is a filter that cuts frequencies below a certain frequency (bass frequencies) and lets through treble frequencies.

The low pass filter is a filter that cuts frequencies above a certain frequency (treble frequencies) and lets through bass frequencies.

The slope is a value expressing the attenuation of the signal in decibels when the frequency is increased or decreased by one octave.

The higher the slope value, the steeper the slope.

If the slope is set to “OFF”, the signal does not pass through the filter, so there is no effect.

In order to protect the speakers, the front high range high pass filter cannot be turned off (the slope cannot be set to “OFF”).

For the same reason, the subwoofer low pass filter cannot be turned off (the slope cannot be set to “OFF”).

Tweeters may be damaged if low frequency signals are input to them.

MP3 and WMA recorded Discs with a sampling frequency of 32 kHz cannot be compensated above 16 kHz.
