JBL VTX M: stage monitors for demanding, maximum power applications
Integrated by the VTX M20 and VTX M22 models, This line incorporates Differential Drive neodymium woofers, D2 high-frequency transducers with double diaphragm and new high-frequency waveguides (Image Control Waveguide) to provide optimal control and gain before feedback.
The Tour Audio division of JBL Professional has unveiled the premium line of VTX M stage monitors, designed for the most demanding applications.
With an elegant design, this series, composed of the VTX M20 and VTX M22 models, incorporates Differential Drive neodymium woofers, D2 high-frequency transducers with double diaphragm and new high-frequency waveguides (Image Control Waveguide) to provide optimal control and gain before feedback.
The VTX M20 features dual woofers 10 inches and a D2 compression motor of 3 inches, while the VTX M22 has the same compression driver and dual woofers of 12 inches. Both models are available in Spain and Portugal from Earpro.
“The M series is the first line of stage-specific monitors in JBL's VTX family of products., para Touring. By working with some of the best monitor technicians in the business, We came to the conclusion that we had to satisfy their needs and make up for the shortcomings of other monitoring solutions.. To achieve our goals, We mix the best of JBL technology with new components that were developed from scratch specifically for these monitors. As a result, These premium stage monitors are prepared for the most demanding and maximum power applications.”, comments George Georgallis, Product Manager, Tour Sound Amps, Speakers and DSP.
The M series high frequency section uses the D2430 3-speed dual compression driver.”, which is the same one that the VTX V25-II large format line array models incorporate. The D2 transducer is coupled to a new high-frequency waveguide with coverage of 60×60 degrees, which has a shape specifically adapted for this series and for stage monitoring applications.
This waveguide is based on JBL's Image Control Waveguide technology., Originally developed for JBL M2 studio monitors. Coupled to transducer D2, offers a very consistent coverage pattern, allowing the M series to achieve excellent gain before feedback.
VTX M series woofers use neodymium Differential Drive technology, allowing excellent heat dissipation, low distortion and very high power. They have dual 3 coils″, which is more than double the coil area of traditional designs.
One of the best features of this design is its surprisingly low weight., which makes the M series one of the lightest in its category, with half the weight of many references from other brands. The two woofers are supported by a bass-reflex enclosure with a large low-frequency port, which allows the system to reproduce low frequencies up to 50 Hz with minimal noise and turbulence.
The M series allows for both dual channel operation modes (bi-amplified) as unique (passive), which can be configured in the easy access switches section. This reduces the cost per mix, allowing the M series to be the ideal solution for a much larger audience.
When single channel mode is selected (passive), An internal passive network is activated that allows amplification with a single amplification channel, reducing overall amplification requirements. Unlike typical passive monitors, The M series divides cabinet preset responsibilities between the amplifier's DSP and the internal passive network.
The external DSP is responsible for correcting the frequency response, linearization of phase response and component protection, while the internal network is only responsible for the high-pass and low-pass filters. The combination of internal and external processing recreates a bi-amplified speaker preset, but using only one amplification channel. The frequency, phase response and maximum output power is identical in both bi-amplified and passive modes.
Like all other JBL VTX products, The M series is exclusively powered by Crown Itech HD DSP-based stages, allowing optimal performance and consistency. In single channel mode, a single Crown 4x3500HD amplifier can power up to 8 M series monitors (in four independent monitor mixes), creating a compact monitoring system.
