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
speakers frequency response.
