Digital delivery package
One of the 2029A Digital units (Right)
has a matching RCA connector in the
back of the unit. Locate the RCA con-
nector (see figure 2) and notice the
signal indicator LED in the front. Con-
nect the RCA cable and switch on the
power on both speakers. The LED
should change colour from green to
yellow.
Please make sure that you can identify
these parts.
1. Two loudspeakers
2. Two mains cables.
3. One interconnect cable, with
male XLR connectors on both
ends.
If you see the LED flashing red co-
lour, check your cabling. Red co-
lour indicates a bit error in trans-
mission.
Turn the output level at the left speaker
to maximum value. This calibrates the
balancebetweenthespeakers.Adjust
the desired output level at the right
speaker (the one receiving the digital
audio). Note that the output level ad-
justment scales the maximum sound
pressure level produced by the digital
audio signal. Monitoring at very low
output levels may not be accurate.
4. A user manual
After unpacking, check that the mains
voltage selector (see figure 2) is cor-
rectly set and place the loudspeakers
at their listening position, taking note
of the listening axis (see figure 1). En-

How to set up for analog signals
Remove the digital audio cable at the
2029A Digital. Observe that the LED
should turn green.
Remove the interconnect cable be-
tween the two Genelec 2029A Digital
units.
To help you solve any problems, here
are a few pointers.
How to set up for digital signals
Run normal XLR cables from your an-
alog audio source to the XLR connec-
tors on both 2029A Digital units.
Connect the special interconnect ca-
ble between the XLR connectors of the
two 2029A Digital monitors.
• Make sure that your audio signal
source has been set to transmit the
audio to the S/P-DIF output.
Adjust the output levels at the front of
both 2029A Digital units independent-
ly for left and right channels.
Connect an digital audio interface
cabletoyour digitalaudiosource. You
can identify the right RCA connector
on your audio source by looking for the
words “Digital Output” or “S/P-DIF”. If
you are sure your audio source has a
digitalaudiooutput,butthecabledoes
not fit the connector, you may have an
equipment that is using a BNC con-
nector instead of the standard RCA.
You can find interface plugs that con-
vert the BNC to an RCA. Before you
• Make sure the digital interface ca-
ble is properly connected at both
ends.

How to set up Genelec 1091A
subwoofer
A standard Genelec 1091A subwoof-
erpackagecontainscablestoconnect
to both 2029A Digital units. The cables
have 1/4" (6mm) plugs that connect to
the 2029A Digital units (see figure 5).
On each 2029A Digital, flip the tone
control switch number 2 to "ON" posi-
tion. This is the right setting when the
subwoofer 1091A is used.
Setting tone controls
The response of the system may have
to be adjusted to match the acoustic
environment. The adjustment is done
by setting the tone control switches on
the rear panel. The tone control has
fourswitchesandcanadjust'trebletilt',
'bass tilt' and 'bass roll-off.' The facto-
ry settings for these are 'ALL OFF' to
give a flat anechoic response. See
Figure 6 for suggested tone control
settings in differing acoustic environ-
ments. Figure 8 shows the effect of the
controls on the anechoic response.
Always start adjustment by setting all
switches to 'OFF' position. Then set a
switch to 'ON' position to select the
necessary response curve.
Figure 3. Cabling scheme for digital setup
5. Monitor placement.
Console top mounting.
Avoid mounting Genelec 2029A Digit-
al monitors directly on the console top.
Instead, position the speakers slightly
behind the console by using floor
stands, wall mounts or microphone
stands. This minimizes sound colour-
ing reflections from the console sur-
face.
Figure 4. Cabling scheme for analog setup
Room placement.
To produce a true and accurate stereo
image the monitors must have exactly
similar frequency responses. When
placed in a room monitor responses
change due to reflections of the sound
waves from the room’s boundaries. It
is necessary to place the monitors at
the same height and also at the same
distance from the front and side walls
so that reflections, and therefore
changes to the frequency response,
are similar.
To avoid differences in frequency re-
sponses due to reflections from the

be used in conjunction with the wall
hanging key holes. The 2029A Digital
can be placed horizontally or vertical-
ly. Enclosed is also a bag containing
four large and four small friction pads.
The larger pads are for the base of the
2029A Digital, and if placed horizon-
tally, the smaller pads may be used on
the side. There are recesses on the
speaker cabinet where the pads fit.

7. Safety Considerations
The 2029A Digital has been designed
in accordance with international safe-
ty 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 should only
be performed by qualified service per-
sonnel.
Figure 7. Tone control switches on the back panel of 2029A Left. Note that the digital audio
receiving speaker (Right) has different labelling.
Do not use this product with an un-
earthed mains cable as this may com-
promise electrical safety.
front wall, the monitors should be
placed either nearer than 1m or further
than 3m from the front wall. Placement
close to the front wall (<1m) will boost
low frequencies, and the tone controls
should be adjusted appropriately (see
figure 6).
This equipment is capable of produc-
ing sound pressure levels in excess of
85 dB, which may cause permanent
hearing damage.
Free flow of air behind the loudspeak-
er is necessary to maintain sufficient
cooling.Donotobstructairflowaround
the loudspeakers.
The monitors should be aimed toward
the listening position. This maximizes
the ratio of direct sound to reflected
sound and the listener is able to hear
more of the material and less of the
room effects. Subjectively this is per-
ceived as cleaner sound and superior
stereo imaging.
Do not insert any objects through the
bassreflexportsonthefaceoftheunit,
as this may damage the electronics in-
side the loudspeaker.
Do not run an analog audio signal to
the digital input RCA connector. Do-
ing so may overload your audio equip-
ment output and cause them perma-
nent damage.
