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
