Genelec 2029B Digital Monitoring
System has a 96 kHz/24 bit digital
audio interface allowing you to input
the digital audio straight into the loud-
speaker. This has several significant
advantages. When you are working
with a digital audio workstation or you
are processing audio in a modern stu-
dio, your signal is digital. The 2029B
allows you to listen to 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. You can even use the
2029B as an analog speaker.
Due to its compact size, integrated
construction, excellent dispersion and
precise stereo imaging, this speaker
system is ideal for near field monitor-
ing, mobile vans, digital audio work-
stations, broadcast and TV control
rooms, surround sound systems,
home studios, multimedia applica-
tions and also computer soundcards.
As an active speaker this unit con-
tains all you need: drivers, power am-
plifiers, active crossover filters and
protection circuitry. The Directivity
Control Waveguide (DCW™) technol-
ogy provides excellent frequency bal-
ance even in difficult acoustic envi-
ronments.

The quality of a digital audio signal is
defined by the two parameters: word
length and sampling rate.
The word length defines how precise-
ly the audio signal is represented.
Longer word length 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
2029B Digital Monitoring System
digital audio signal. A higher
sampling rate allows higher frequen-
cies to be recorded. Studio recording
systems use sampling rates of 44.1
kHz and above.
Turning the digital presentation to an
analog signal using a D/A converter
involves potential sources of error. The
digital-to-analog converter may have
inferior performance or it may be mis-
aligned with your amplifiers. The in-
terface 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 in-
stead of analog. Genelec 2029B al-
lows you to solve all of these prob-
lems. The alignment of the whole sys-
tem 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.

As the digital interface and amplifiers
are built into the speaker enclosure,
the only connections required are the
mains supply and the digital input sig-
nal, making the 2029B very easy to
set up and use.

The digital audio interface comprises
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 sampling rate
up to 100 kHz. The D/A converter has
high resilience to clock jitter and ex-
cellent linearity.

The bass frequencies are reproduced
by a 130 mm (5") bass driver mount-
ed in a 4.5 litre vented cabinet. The
-3 dB point lies at 68 Hz and the fre-
quency response extends down to
65Hz (-6 dB).
The high frequency driver is a 19 mm
(3/4") metal dome. Uniform disper-
sion is achieved with the revolution-
ary DCW™ Technology pioneered by
Genelec.
Magnetic shielding is standard on
Genelec 2029B. Shielding is vital for
applications such as video post pro-
duction, where stray magnetic fields
must be minimized.

The active crossover network is acous-
tically complementary and the slopes
are 24 - 32 dB/octave. The crossover
frequency is 3.3 kHz. The room re-
sponse controls ('treble tilt', 'bass tilt'
and 'bass roll-off') allow perfect re-
production in any room installation.

The amplifier unit is built inside the
speaker enclosure. The bass and tre-
ble amplifiers both produce 40 W of
output power. The fast, low distortion
amplifiers are capable of driving a ster-
eo pair to peak output sound pres-
sure levels in excess of 110 dB at 1
m. The unit incorporates special cir-
cuitry for driver overload protection.

After unpacking, check that the mains
voltage selector (see figure 2) is cor-
rectly set and place the loudspeak-
ers at their listening position, taking
note of the listening axis (see figure

nated as "Right" and "Left" (see the
stickers on the speaker's backpan-
els). The "Right" speaker, which con-
tains the digital interface also has a
