The controls are "Treble Tilt", "Bass Tilt" and "Bass
Roll-Off". An acoustic measuring system such as
WinMLS or comparable is recommended for ana-
lyzing the effects of the adjustments, however,
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 1) attenuates the tre-
ble response of the loudspeaker at frequencies
above 5 kHz by 2 dB, which can be used for
smoothening down an excessively bright sound-
ing 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 3 "ON"), -4
dB (switch 4 "ON") and -6 dB (both switches "ON").
Bass Roll-Off
Bass Roll-Off (switch 2) activates high-pass filter-
ing at 85 Hz to complement the low-pass filters of a
Genelec 7050 subwoofer. This switch should always
be set to "ON" when using the 8020C with these
subwoofers.
The factory setting for all tone controls is "OFF"
to give a flat anechoic response. Always start ad-
