Level control
The input sensitivity of the loudspeaker can be
matched to the output of the signal source by
adjusting the level control on the rear panel.
Setting the tone controls
The frequency response of the Genelec
4030C 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, however, careful
listening with suitable test recordings can also
lead to good results if a test system is not
available. 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
The Treble Tilt control (switch 1) boosts the treble
response of the loudspeaker at frequencies above 5
kHz by +2 dB, which can be used for compensating
for the high frequency loss at long distance.
Bass Tilt
The 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.
