FEATURES

• Image Control Waveguide:
  • The Image Control Waveguide was developed for JBL's new flagship M2 Master Reference Monitor and with the introduction of the JBL 3 Series, is now included for the first time in an affordable, compact reference monitor.
  • The patent-pending design of the Image Control Waveguide precisely controls the sound emanating from the speaker in the vertical and horizontal planes ensuring the presentation at the listening position is neutral and accurate.
• JBL Transducers are legendary for their performance. The 3 Series long-throw woofer and its damped woven composite Neodymium tweeter are designed from the ground up to reproduce the powerful transients and micro dynamics of your mix. These drivers deliver impressive deep bass and smooth high frequency response beyond the range of human hearing.
• JBL's Patented Slip StreamTM low frequency port design works in concert with the woofer to produce deep bass response at all playback levels. The double-flared shape of the port is precisely engineered for greater low-frequency extension and reduced turbulence.
• Big Power, Big Sound - 3 Series efficient Class D Amplifiers provide abundant power to deliver the output and dynamic headroom needed for the most demanding production styles
• Professional Balanced Inputs - Balanced XLR and 6 mm TRS inputs give you the options you need to connect your 3 Series to any signal source while maintaining professional signal quality.
• Selectable Input Sensitivity - The -10 dB/+4 dB sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect the 3 Series to high output professional gear without any danger of input overload.
• LF Trim and HF Trim "TRIM" switches for both the Low and High Frequencies give you excellent control over the 3 Series sound in "your" room. Use these to fine-tune the amount of bass and treble you hear to compensate for room acoustics, program material and your personal taste.
• JBL Professional Reliability - Prior to becoming a production-ready design, each 3 Series model is subjected to JBL's tough 100 hour power test, in which the speaker is required to play continually at full output for 100 hours without failure. This demanding test ensures your 3 Series speakers will deliver years of reliable performance.
• JBL LSR Design - Your Music Needs a Point of Reference - While most manufacturers take only a single on axis measurement of the speaker's performance, this doesn't tell how it will sound in your room. JBL's LSR Linear Spatial Reference design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker that "sounds right" in any working space. With LSR design, 3 Series Studio Monitors deliver superior accuracy regardless of the size and shape of your room, so your mixes "hit their mark" when heard on any playback system.

S3X-V

Using the newly developed 4” HexaCone midrange and 9” HexaCone woofer combined together with the X-ART tweeter creates the unique S3X-V control monitor.

A step up over the smaller models, the S3X-V is capable of producing more power and volume along with a more detailed and homogeneous sound that will impress even the most experienced sound engineer. Whether the complex sonic images of an orchestra or the smooth tone of a jazz trio, the S3X-V reveals even the finest nuances of any material. The driver assembly of the S3X-V allows long time, non-fatiguing listening sessions.

Reviews: "Wonderfully detailed...”

“Wonderfully detailed, with an exceptionally transparent mid-range. [...] ADAM make the leap to a three-way speaker design that seems to pay dividends in clarity and separation. [...] I think it would be fair to say theyʽre the best sounding ADAM monitors Iʽve reviewed.” (Sound On Sound, 12/2009)

“No doubt, the S3X-V deserve the title Reference Monitor. With this series, ADAM Audio proves to have a very good feeling for meeting the specific demands of the sound engineerʽs guild, creating studio standards at the same time. [...] A precision tool combined with a luxury good.” (www.96kHz.de, 03/2010)

ADAMs A7 & A7X: the evolution of a legend

The predecessor to the A7X, the A7, became the most famous of all ADAM monitors in a very short time. Not only has it been reviewed over three dozen times with outstanding results, it has also received numerous awards. The A7 quickly gained mass appeal, praised in many of the worldʼs largest internet forums. Still today, the A7 are the reference monitors in many smaller studios.

With the A7X, ADAM Audio proudly presents the evolution of a legend. It takes everything that made the A7 such an outstanding speaker to a new level.

Driver technology

The first aspect that distinguishes the old from the new model is the X-ART tweeter. The ʽXʼ stands for ʽeXtended frequency responseʼ and thus for one of the features of the Accelerating Ribbon Technology that has been drastically improved: the frequency response. It now extends all the way up to 50kHz. In addition, the X-ART tweeter has a higher efficiency and higher maximum sound pressure levels.

The perfect integration with the lower frequencies has been achieved with a newly designed 7” midwoofer. It has been redesigned with a much bigger voice coil (1.5”) and is driven by an amplifier with twice the power compared to its predecessor. This combination produces an amazing sound and pressure levels with an almost distortion-free musical reproduction.

Amplifiers / controls

Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the midwoofer is being driven by a 100W PWM amp. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.

On the rear panel are several additional controls: a gain for the high frequencies (± 4dB) and two shelf filters for high and low frequencies.
To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.

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.
