GENERAL DESCRIPTION
Genelec 2029B Digital Monitor-
ing System has a 96 kHz/24 bit
digital audio interface. This has
several significant advantages.
When you are working with a digital audio workstation or you are
processing audio in a modern studio, your signal is digital. The
2029B allows you to monitor what
you have in your digital format.
The 2029B supports all the same
modes of operation as the analog
Genelec 1029A. You can use it
with a subwoofer. You can use it
in surround audio systems.
Due to its compact size, integrated construction, excellent
dispersion and precise stereo imaging, the 2029B system is ideal
for near field monitoring, mobile
vans, digital audio workstations,
broadcast and TV control rooms,
surround sound systems, home
studios, multimedia applications
and also for use with computer
soundcards. The Directivity Control Waveguide (DCW™)
technology provides excellent
frequency balance even in difficult acoustic environments.
leads to smaller noise and distortion level. The typical word length
in CD records is 16 bits. Studio
recording systems use word
lengths of 20 bits and above.
The sampling rate determines
what frequencies can be represented in the digital audio signal.
A higher sampling rate allows higher frequencies to be recorded.
Converting the digital presentation to an analog signal using a D/
A converter involves potential
sources of error. Your digital-toanalog converter may have
inferior performance, or it may be
misaligned with your amplifiers.
The interface between the converter and the amplifier may distort
the signal or change the frequency balance. The monitoring
volume level may need to be
adjusted in the digital domain instead of analog. Genelec 2029B
allows you to solve all of these
problems. The alignment of the
whole system from the digital input connector is carefully
balanced, to make sure that you
hear the whole digital truth, and
nothing but the truth. All you have
to do is to supply the digital signal, and adjust for the volume you
desire.
INTEGRATED
CONSTRUCTION
As the digital interface and amplifiers are built into the speaker
enclosure, the only connections
required are the mains supply
and the digital (or analog) input
signal, making the 2029B very
easy to set up and use.
DIGITAL AUDIO
The quality of a digital audio sig-
nal is defined by two parameters:
word length and sampling rate.
The word length defines how precisely the audio signal is
represented. Longer word length

FOR AES/EBU SIGNAL
The digital audio input comprises
of a digital audio receiver and a
digital-to-analog converter (D/A
converter). The digital input accepts an AES/EBU digital audio
signal having a word length up to
24 bits and up to 100 kHz sampling rate. The D/A converter has
high resilience to clock jitter and
has excellent linearity.
DRIVERS
The bass frequencies are repro-
duced by a 130 mm (5") bass
driver mounted in a 4.5 litre vented cabinet. The -3 dB point lies
at 68 Hz and the frequency response extends down to 65 Hz
(-6 dB).
The high frequency driver is a 19
mm (3/4") metal dome. Uniform
dispersion control is achieved with
the revolutionary DCW™ Technology pioneered by Genelec.
Magnetic shielding is standard
on Genelec 2029B. Shielding is
vital for applications such as video post production, where stray
magnetic fields must be minimized.
CROSSOVER
AMPLIFIERS
The amplifier unit is built inside the
speaker enclosure. The bass and
treble amplifiers both produce
40 W of output power. The fast,
low distortion amplifiers are capable of driving a stereo pair to
peak output sound pressure levels in excess of 110 dB at 1 m. The
unit incorporates special circuitry for driver overload protection.
DIGITAL AND ANALOG
SIGNAL MANAGEMENT
The digital interface is housed in
the speaker marked as "RIGHT
SPEAKER". The balanced AES/
EBU digital signal is fed into this
unit via a XLR connector. In digital
mode the speakers are connected to each other with a balanced
cable, which carries the converted analog signal to the "Left"
speaker. In digital mode the output level for both speakers is
controlled with the potentiometer
on the "Right" unit. The balance is
adjusted with the potentiometer
on the "Left" unit.
In analog mode both speakers
are connected individually to the
signal source with balanced audio cables. In this mode the output
level is adjusted separately on
each 2029B unit.
panel. The tone control has four
switches and can adjust 'treble
tilt', 'bass tilt' and 'bass roll-off.'
The factory settings for these are
'ALL OFF' to give a flat anechoic
response. Figure 5 overleaf
shows the effect of the controls
on the anechoic response.
MOUNTING OPTIONS
There are several possibilities for
mounting the 2029B Digital. On
the base of the monitor is a
3
UNC threaded hole which can accommodate a standard
microphone stand. There is a
provision for an Omnimount®
size 50 bracket,for which two
M6x10mm screws are required.
Alternatively the speaker can be
hung on M4 screws with suitable
heads by one of the three keyhole slots on the backpanel. The
speaker can be hung in a horizontal or vertical position. Friction
pads are provided for placement
on a shelf or a stand.

The active crossover network is
acoustically complementary and
the slopes are 24 - 32 dB/octave.
The crossover frequency is 3.3
kHz. The room response controls ('treble tilt', 'bass tilt' and
'bass roll-off') allow exact match
to any installation.
TONE CONTROLS
The response of the system usu-
ally has to be adjusted to match
the acoustic environment. The
adjustment is done by setting the
tone control switches on the rear
