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.

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 2) 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 4 "ON"), -4
dB (switch 5 "ON") and -6 dB (both switches "ON").
