the same distance from the front and
side walls so that reflections, and
therefore changes to the frequency
response, are similar. Smaller objects,
such as equipment racks also cause
reflections and disturb the imaging,
so they too should be placed sym-
metrically in the room.
To avoid differences in low frequency
responses due to reflections from the
front wall, the monitors should be
placed either nearer than 1m or fur-
ther than 3m from the front wall. Place-
ment close to the front wall (<1m) will
boost low frequencies, and the tone
controls should be adjusted appro-
priately (see figure 6).
The monitors should be aimed toward
the listening position. This maximiz-
es the ratio of direct sound to reflect-
ed sound and the listener is able to
hear more of the material and less of
the room effects. Subjectively this is
perceived as cleaner sound and su-
perior imaging.

To help you solve any problems, here
are a few pointers:
• Make sure that your audio
signal source has been set
to transmit the audio to the AES/
EBU output.
• Make sure the digital cables are
specified for use with AES/EBU
digital audio signals and properly
connected at both ends.
• Make sure the LED turns yellow
as you plug in the digital audio ca-
ble to the S30D unit. If this is not
the case, go back to your audio
source and check once more that
the right output is selected. If the
LED stays green you do not have
a valid digital audio carrier on the
cable.
• If you see the LED flashing red
colour, check your cabling. Red co-
lour indicates a bit error in trans-
mission.

Genelec S30D has been designed in
accordance with international safety
standards. To ensure safe operation
and to maintain the instrument in safe
operating condition, the following
warnings and cautions must be ob-
served:
• Servicing and adjustment may
only be performed by qualified
service personnel.
• Do not use this product with an
unearthed mains cable as this may
compromise electrical safety.
• This equipment is capable of pro-
ducing sound pressure levels in
excess of 85 dB, which may cause
permanent hearing damage.
• Free flow of air behind the loud-
speaker is necessary to maintain
sufficient cooling. Do not obstruct
airflow around the loudspeakers.
• Do not insert any objects through
the bass reflex port(s) on the face
of the unit, as this may damage the
drive units inside the loudspeaker.
• Do not run an analog audio sig-
nal to the digital input XLR connec-
tor. Doing so may overload your
audio equipment output and cause
them permanent damage.
