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.

mains supply and the digital input signal, making the 2029A Digital very easy to set up and use.
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.
DRIVERSDRIVERS
DRIVERS
DRIVERSDRIVERS 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
CROSSOVER
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.
AMPLIFIERSAMPLIFIERS
AMPLIFIERS
AMPLIFIERSAMPLIFIERS 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 IEC958 interface cable from your digital audio source connects to one of the 2029A Digital units.
In the digital audio reproduction mode the output level for both speakers pair is controlled with the right unit. The balance is automatically calibrated correctly with the proposed output level setting on the left unit.

TONE CONTROLSTONE CONTROLS
TONE CONTROLS
TONE CONTROLSTONE CONTROLS 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.

MOUNTING OPTIONSMOUNTING OPTIONS
MOUNTING OPTIONS
MOUNTING OPTIONSMOUNTING OPTIONS 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.
