GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
Genelec 2029A Digital near field
monitor has a 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
2029A Digital allows you to
monitor what you have in your
digital format.
The 2029A Digital supports all the
same modes of operation as the
analog 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, this speaker 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.
sampling rate. The word length
defines how precisely 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 digital audio
signal. A higher sampling rate
allows higher frequencies to be
recorded.
Turning the digital presentation to
an analog signal using a DA
converter involves significant
sources of error. Your digital-toanalog converter may have
inferior performance. It may be
misaligned with your amplifiers.
The interface between the
converter and the amplifier may
distort the signal or it may
change the frequency balance.
Your monitoring volume level may
need to be adjusted in the digital
domain instead of analog.
Genelec 2029A Digital 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.

Digital very easy to set up and

DIGITAL INTERFACEDIGITAL INTERFACE
DIGITAL INTERFACE
DIGITAL INTERFACEDIGITAL INTERFACE
The digital audio input comprises
of a digital audio receiver and a
digital-to-analog converter (DA
converter). The digital input
accepts an S/P-DIF digital audio
signal having a word length up to
24 bits. The DA converter has an
interpolator increasing the internal
sampling rate to four times the
original before a fourth order
delta-sigma modulator, and a
digital-to-analog conversion in a
switched capacitor integrator and
an analog low-pass filter. This
conversion process has high
resilience to clock jitter and has
excellent linearity.

The bass frequencies are
reproduced 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 2029A Digital.
Shielding is vital for applications
such as video post production,
where stray magnetic fields must
be minimized.
CROSSOVERCROSSOVER

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.

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.

The response of the system
usually has 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 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 6 overleaf shows the effect
of the controls on the anechoic
response. Always start adjustment by setting all switches to
'OFF' position. Then set the
switch if needed to the 'ON'
position to select the response
curve needed.

There are several possibilities for
mounting the 2029A Digital. On
the base of the monitor is a 3/8"
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.
