0.5 watts. The loudspeakers will automatically and
rapidly start once an input signal is detected from
the source.
Setting the volume control
The input sensitivity of the loudspeaker can be
matched to the output of the audio signal source by
adjusting the volume control on the front panel.
Setting the tone controls
The frequency response of Genelec 8030B 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 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.
Figure 4 shows the effect of the controls on the
anechoic response.
Treble Tilt
Treble Tilt (switch 1) attenuates the treble response
above 5 kHz by 2 dB, which can be used for smooth-
ening down an excessively bright sounding system.
Bass Tilt
Bass Tilt offers three attenuation levels for the bass
response below 1 kHz, usually necessary when the
loudspeakers are placed near room boundaries.
The attenuation levels are -2 dB (switch 3 “ON”), -4
dB (switch 4 “ON”) and -6 dB (both switches “ON”).
