Setting the tone controls
The frequency response of the Genelec 8020C
can be adjusted to match the acoustic environment
by setting the tone control switches on the rear
panel. The controls are “Treble Tilt”, “Bass Tilt” and
“Bass Roll-Off”. An acoustic measuring system
such as WinMLS or comparable is recommended
for analyzing the effects of the adjustments, how-
ever, careful listening with suitable test recordings
can also lead to good results. Table 1 shows some
examples of typical settings in various situations.
Figure 4 shows the effect of the controls on the
anechoic response.
Treble Tilt
Treble Tilt control (switch 2) attenuates the treble
response of the loudspeaker at frequencies above
5 kHz by 2 dB, which can be used for smoothening
down an excessively bright sounding system.
Bass Tilt
Bass Tilt control offers three attenuation levels
for the bass response of the loudspeaker below
2 kHz, usually necessary when the loudspeakers
are placed near a wall or other room boundaries.
The attenuation levels are -2 dB (switch 4 “ON”), -4
dB (switch 5 “ON”) and -6 dB (both switches “ON”).
Bass Roll-Off
Bass Roll-Off (switch 3) activates high-pass filter-
ing at 85 Hz to complement the low-pass filters of
a Genelec 7050A or 7050B subwoofer. This switch
should always be set to “ON” when using the 8020C
with these subwoofers.
