speaker to an unearthed mains supply or using an
unearthed mains cable.
Audio input is via a 10 kOhm balanced female
XLR connector labelled "INPUT". An unbalanced
source may be used as long as pin 3 is grounded
to pin 1 at the unbalanced source connector (see
Figure 2).
The male XLR "OUTPUT" connector can be
used for daisy-chaining up to six 8030A's together
or for connecting a Genelec 7050B subwoofer. The
volume control attenuates the signal on this output,
so the first "master" loudspeaker on a daisy-chain
can be used to adjust the level on the whole chain.
The volume controls on the "slave" loudspeakers
should be set fully clockwise.
Once the connections have been made, the
loudspeakers are ready to be switched on.

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 8030A 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.
