Important points in adjusting the slope

A decrease in the absolute value of the slope (more gentle inclination) makes the frequency characteristics more susceptible to interference from the next band.

Increasing the absolute value of the slope (sharper inclination) lessens the connections between bands, giving the listener the impression of hearing separate, unrelated sounds.

Make adjustments while monitoring the link between bands by outputting all the bands as well as by outputting two neighboring bands only, using the mute function (refer to page 37).

Important points in adjusting the phase (when using minimum delay phase characteristics)

When the values of the slope at the crossover point are set at –12 dB/oct. or –36dB/oct. for both filters, the phase reverses 180˚ in the cut-off frequency of the filter. In this case, setting to reverse improves the connection between sounds.

For better frequency characteristics

Adjusting the filter together with the equalizer function (page 20) creates a natural sound environ- ment in the car.

Adjusting the subwoofer effectively

Although the slope of the high pass filter is normally set as PASS, H.P.F. may sometimes repro- duce clear and high quality bass rage. In this case, adjust the cut-off frequency to 20 Hz to 40 Hz and adjust the slope to –18 dB/oct. to –72 dB/oct.

If the subwoofer is installed in the rear tray, setting up the slope of the low pass filter gently

(–6 dB/oct. , –12 dB/oct.) gives the listener the feeling that the sound dwindles to the rear, with a resultant distortion of the forward sound image position. It is recommended to set the slope at –18 dB/oct. or more and set the cut-off frequency to 100 Hz or below.

Adjusting the low-range effectively

When the subwoofer is connected and low-ranges are reproduced by small speaker unites such as 10 cm or less than 13 cm in diameter, setting the low-range H.P.F. as PASS may increase the dis- tortion when strong bass signals enter. Should this occur, set up H.P.F. to avoid interference with the subwoofer.

Adjusting the high-range effectively

Depending on the speaker units installed, bass signals for the tweeter (about 2 kHz or below) may cause distortion as the high pass filter is being adjusted. If this happens, set a sharp slope of

–18 dB/oct. to –72 dB/oct. In this case, choose such settings that the mid-range and tweeter do not become separated.

The low pass filter is generally set to PASS. However, if the ultratreble band falls harshly on the ear, it is possible to set up a more gentle slope of about –6 dB/oct.
