Treble tilt control
Treble tilt (third switch group from the left)
allows adjusting the treble response above
5 kHz by +2, -2, or -4 dB, which can be used
for correcting an excessively bright or dull
sounding system.
An acoustic measuring system such as
MLSSA or WinMLS is recommended for
analyzing the effects of the adjustments,
however, careful listening with suitable test
recordings can also lead to good results if a
test system is not available. Table 1 shows
some typical settings in various situations.
Figures 8 and 10 show the effect of the con-
trols on the anechoic response.
Always start adjustment by setting all
switches to "OFF" position. Then set only
one switch per group to the "ON" position to
select the desired adjustment. If more than
one switch is set to "ON" (within one switch
group) the attenuation value is not accurate.
Measure or listen systematically through
the different combinations of settings to find
the best frequency balance.
