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.

The smallest big sound ever...

With the A3X, ADAM Audio present their smallest monitor to date, making it perfectly suited for all environments where space is limited but sound shouldnʼt be constricted. The A3X combines a tiny footprint with the much acclaimed ADAM sound quality by using the X-ART tweeter for the higher frequencies, a guarantee for crystal clear music reproduction.

A 4.5” (basket) driver handles the lower registers. The diaphragm is made from carbon fiber, a material that is very light but very stiff and therefore capable of delivering colouring-free sound. Two built-in 25 Watt amplifiers powers each of the drivers directly.

Stereolink

A very handy and exclusive technology found in the two smaller AX monitors is the Stereolink. This is accomplished by a pair of additional RCA connections that allow for a bypass of the second stereo channel to the other speaker.

This new technology connects two A3X speakers in such a manner as to allow the user the option to control the overall stereo volume of the system from either speakerʼs gain control. This makes the A3X a natural for "mixer-less” desktop applications where overall system volume needs to be adjusted easily.

Controls and Connectors

The front of the A3X sports dual ports for surprisingly low frequency response down to 60Hz. The front panel also has power and gain controls. The rear panel includes a tweeter gain control as well as balanced (XLR) jacks and unbalanced (RCA) jacks, allowing for greater connection flexibility. There are also two M6 (6 mm) metric screw threads for stand/wall mounting.

Review: "Highly recommended“

"Iʼve used various monitors for my computer work before, but never of the caliber of the A3X series. Before these, I would have to redo my mixes significantly when transitioning from the small cheapies to the big 'real ones'. The ADAM Audio A3Xʼs save me a step by providing both great sound in a compact format and by changing mundane audio task-work into a quality listening experience. If you use good monitors from the outset, youʼll learn your music that much faster so that when it comes time for mixdown and mastering on your big boxes, youʼll already be acclimated to your songʼs subtler sonic aspects—aspects revealed only by the A3Xʼs with their sweet, smooth top end, and impressive handling of bass frequencies. Highly recommended.“

Review: "...one of the best compact monitors“

"ADAM´s A3X as the smallest monitor with a X-ART tweeter to date has convinced us in every respect. It´s one of the best compact monitors we have ever reviewed and with its almost shameless low price it´s worth every penny. (Professional Audio, 05/10)

MYTHO 8 is a two-way reference studio monitor equipped with two separate AB amplifiers - 200 W for the low frequencies and 100 W for the high - unparalleled for low distortion and natural sound. It features a high quality large metal dome tweeter for the best vocal reproduction and a 8” neodymium vented woofer with a large sized 51 mm voice coil that guarantees very high energy for tight and controlled bass reproduction and perfect thermal stability with minimum power compression.

The magnetic circuit features a special air ventilation to reduce air compression, air noises and minimize distortion in large excursion situations. Thanks to the deeper low frequencies reproduced by its 8” woofer, the MYTHO 8 is perfect for medium to large control rooms.
A dedicated high quality DSP is provided on board. The cabinet is made in aluminium, internally braced and reinforced to improve low frequencies behaviour and reduce resonances.
