adjusted to match the acoustic environment by setting the
tone control switches on the rear panel. The controls are
“Desktop 200 Hz”, “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. Table 1 shows some examples of typical settings in
various situations. Figure 4 shows the effect of the controls
on the anechoic response.
Desktop 200 Hz
The desktop low frequency control (Switch 2) attenuates the
bass frequencies around 200 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 control (switch 3) 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 6 “ON”), -4 dB (switch 7 “ON”) and -6 dB
(both switches “ON”).
Bass Roll-Off
Bass Roll-Off (switch 4) activates a -4 dB filter to the lowest
bass frequencies (65 Hz). This can be used for compensating
