Setting the tone controls
The frequency response of the 8030C can be
adjusted to match the acoustic environment by
setting the tone control switches on the rear panel.
The controls are “Desktop”, “Treble Tilt”, “Bass Tilt”
and “Bass Roll-Off”. An acoustic measuring system
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.
Desktop
The desktop low frequency control (Switch 1)
attenuates the bass frequencies around 160 Hz by
4 dB. This feature is designed to compensate for
the boost often occurring at this frequency range
when the loudspeaker is placed upon a meter
bridge, table or similar reflective surface.
Treble Tilt
Treble Tilt (switch 2) attenuates the treble response
above 4 kHz by 2 dB, which can be used for
smoothening down an excessively bright sounding
system.
Bass Roll-Off
Bass Roll-Off (switch 3) activates a -4 dB filter to
the lowest bass frequencies (55 Hz). This can be
used for compensating excessively heavy bass
reproduction typically caused by loudspeaker
placement near room boundaries.
