Integrated by VTX M20 and M22 VTX models, is line incorporates the neodymium Differential Drive woofer, dual diaphragm D2 high-frequency transducers and a new guide (Image Control Waveguide) high-frequency waves to provide optimum control and gain before feedback.

The Tour Audio division of JBL Professional It has unveiled the line premium VTX M stage monitors, designed for the most demanding applications.

With an elegant design, this series, composed by VTX M20 and M22 VTX, models incorporates the neodymium Differential Drive woofer, D2 Double-diaphragm high-frequency transducers and a new guide of high frequency waves (Image Control Waveguide) to provide optimum control and gain before feedback.

The VTX M20 has dual 10-inch woofers and a 3 inch compressions D2 engine, while the M22 VTX has the same engine of compression and dual 12-inch woofers. Both models are available in Spain and Portugal from the hand of EarPro.

"The M-series is the first product family-specific stage monitors line VTX from JBL, for Touring. Working with some of the best technicians of the sector monitors, we came to the conclusion that we had to meet their needs and fill the gap of other monitoring solutions. To achieve our goals, we mix the best of the JBL technology with new components that were developed from scratch specifically for these monitors. As a result, these premium stage monitors are ready for the most demanding applications and maximum power", says George Georgallis, Product Manager, Tour Sound Amps, Speakers and DSP.

M Series high frequency section uses the compression engine dual D2430 3 ", which is the same as line-array of large-scale VTX V25-II models. D2 transducer is coupled to a new guide high-frequency wave and coverage of 60 × 60 degrees, which has a form specifically adapted for this series and for stage monitoring applications.

Wave this guide is based on the Image Control Waveguide technology of JBL, originally developed for the M2 JBL Studio monitors. Attached to the transducer D2, it offers a very consistent coverage pattern, allowing the M series achieve excellent gain before feedback.

The VTX M series woofers used Differential Drive technology of neodymium, allowing an excellent heat dissipation, low distortion and high power. They have dual coil of 3″, which is more than twice the area of the coil than traditional designs.

One of the best features of this design is its amazing low weight, which makes the M-series of the lightest in its class, with half the weight that many references of other brands. The two woofers are supported by an enclosure bass-reflex with a large port of low frequency, allowing the system to reproduce low frequencies up to 50 Hz with minimum noise and turbulence.

M series allows operation modes both dual-channel (BI) as only one (passive), that they can be configured in the section of easy-access switches. This reduces the cost by mixture, allowing M-series to be the ideal solution for an audience far greater.

When you select a single channel (passive) mode, activates an internal passive network that allow you to amplify with an only amplifier channel, reducing the overall requirements of amplification. Unlike typical passive monitors, M series divided the responsibilities of the preset of the box between the DSP of the amplifier and the internal passive network.

The external DSP is responsible for correcting the frequency response, the linearization of the response phase and the protection of the components, while the internal network is only responsible for the pass and high-pass filters low. The combination of internal and external process recreates a preset of speaker biamplificada, but using only one channel of amplification. The frequency response in phase and maximum power output is identical both in bi mode and passive mode.

Like all other products JBL VTX, the M series is exclusively powered by Crown Itech stages DSP based HD, allowing optimum performance and consistency. In single channel mode, a single amplifier 4x3500HD Crown can power up to 8 monitors of the M series (in four separate monitor mixes), creating a compact monitoring.
