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.
