Hint for adjusting the subwoofer

If the subwoofer is installed on the rear deck, setting a gentle L.P.F. slope (for example 6 dB/ oct.) makes the sound localization more to the rear. This can also affect the acoustic localization of the front.

Hints for adjusting the high range

Depending on the speaker, inputting low frequency component signals (about 2 kHz or less) with the H.P.F. adjustment could result in distortion. If so, set a steep slope (for example 30 dB/oct.).

When doing so, adjust so that the mid and high range sounds do not separate.

Normally use with the L.P.F. off. If the high range is too strong, we recommend adjusting for a gentle slope.

Hint for adjusting the low range

When a subwoofer is connected and you are using a speaker with a low range of under 10 or 12 cm (3-15/16" or 4-3/4"), setting the low range H.P.F. to “OFF” can result in distortion when low frequency components are input.

If so, set the H.P.F. slope to a value suited for the speaker’s frequency response.

NOTES

In order to protect the speakers, if Tweeter is selected in Front 1, there is no filter OFF (slope OFF) setting for H.P.F.

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

When the speaker is set to the “OFF” mode, the X- OVER for that speaker is ineffective. Refer to “Setting the speakers” (page 4).

Check the playback frequencies of the connected speakers before adjusting.

After making the settings, we recommend storing them in the memory. For instructions, see page 28.
