11 Audio Adjustments

You can then make precise adjustments to the reproduced frequency band (with a low-pass filter or high-pass filter), level, phase and other parameters to match the characteristics of each speaker unit.

Adjustable parameters

The network function enables adjustment of the following parameters. Make adjustments in line with the reproduced frequency band and characteristics of each connected speaker unit.

Reproduced frequency band Adjusting the HPF (high-pass filter) or LPF (low-pass filter) cut-off frequency lets you set the reproduced frequency band for each speaker unit.

!The HPF cuts frequencies (low) below the set frequency, letting high frequencies through.

!The LPF cuts frequencies (high) above the set frequency, letting low frequencies through.

Level

The difference in reproduced levels between speaker units can be corrected.

Slope

Adjusting the HPF/LPF slope (filter attenuation slope) lets you adjust the continuity of sound between speaker units.

!The slope indicates the number of decibels (dB) the signal is attenuated when the fre- quency is one octave higher (lower) (Unit: dB/oct.). The steeper the slope, the more the signal is attenuated.

Phase

You can switch phase (normal, reverse) for each speaker unit’s input signal. When the continuity of sound between speakers is im- precise, try switching phase. This may improve the continuity of sound between speakers.

Points concerning network adjustments

Cut-off frequency adjustment

!With the low-range speaker installed in the rear tray, if you set Low LPF cut-off fre- quency high, bass sound is separated so that it appears to come from the rear. You are recommended to set Low LPF cut-off frequency to 100 Hz or lower.

!The maximum input power setting for mid- dle- and high-range speakers is usually lower than that for low-range speakers. Re- member that if Mid HPF or HighHPF cut- off frequency is set lower than required, strong bass signal input may damage the speaker.

Level adjustment

The basic frequencies of many musical instru- ments are in the middle range. First perform middle-range level adjustment, followed by high-range and then low-range level adjust- ment in that order.
