The Genelec 8130A Digital Monitoring System has a 192 kHz/24 bit digital audio interface.
Due to its compact size, integrated construction, excellent dispersion and precise stereo
imaging, the 8130A 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.
The integrated design allows the amplifiers and the drivers to be calibrated as a single unit,
eliminating the effects of component tolerances and ensuring consistent quality.
The all-aluminium Minimum Diffraction Enclosure? (MDE?) and advanced Directivity Control
Waveguide? (DCW?) technologies are carefully matched with advanced amplifier and electronics
circuitry. The low frequency response extends down to 55 Hz (-3 dB) while distortion is extremely
low due to a uniquely new rear reflex port design.
The 8130A has been specially designed to have a sufficient LF extension for most situations.
However if greater SPL's and a lower cutoff frequency are required, it can be complemented
with Genelec 7050B subwoofer.
The 8130A is very easy to set up and use, the only connections required are the mains supply
and the input signal. The female XLR input connector can be fed with either AES/EBU formatted
digital signal or analog line level audio signal. The Genelec 8130A automatically detects analog or
digital signals and directs them to the correct signal paths.

PRICE PER UNIT

The most powerful AX monitor

With its power and radiation characteristics, the brand new A8X is suitable for both nearfield and midfield monitoring. With a price/performance ratio that could hardly be better, this monitor is a perfect entry into these monitoring fields.

The A8X is equipped with the X-ART tweeter and a large (8.5”) midwoofer, a combination that adds both a very deep and yet very tight bass response to the unsurpassed reproduction qualities of the ADAM proprietary tweeter: a licence to thrill.

Cabinet- and bass reflex-construction

Like the other AX-Series models, the upper corners of the A8X are slanted to minimize reflections. The very large, double bass reflex tubes on the front have been specifically designed to perfectly match the midwoofer with its large voice coil.

Amplification and controls

With a 50W A/B amplifier for the tweeter and a 150W PWM amplifier for the midwoofer, the A8X has power in abundance and is the brawny monitor of the AX-Series.

On the rear panel are several controls: a gain for the high frequencies (± 4dB) and two shelf filters for the high and low frequencies.
There are both XLR (balanced) and RCA (unbalanced) connectors on the rear panel of the speaker, which allow the A8X to be used in almost any application.

Review: A8X: a "powerful link" between near- and midfield monitors!

"The A8X is a powerful link between ADAM´s AX Series and the formidable and more expensive SX Series. Its all-in-all homogenous tuning, the deep and precise bass as well as the brilliant mid- and high-frequency reproduction make this speaker a huge recommendation for ambitious people without deep pockets." (Professional Audio 10/2010)
