Anaheim, CA (January 22, 2016)—JBL Professional has released the JBL VTX M Series, a new line of low-profile stage monitors, comprised of the VTX M20 and VTX M22. The M20 features dual 10-inch woofers and a 3-inch D2 compression driver, while the VTX M22 features dual 12-inch woofers and the 3-inch D2 compression driver.
The first dedicated tour sound stage monitoring line in JBL’s VTX family of products, the M Series high frequency section utilizes the D2430 Dual 3-inch compression driver, which is also found in JBL’s large format VTX V25-II Line Array system. The D2 driver is coupled with a newly developed 60×60 degree high frequency waveguide based on JBL’s Image Control Waveguide, a technology originally developed for the JBL M2 Master Reference studio monitor.
The woofers in the VTX M Series utilize JBL’s Differential Drive technology and feature dual 3-inch voice coils. The two woofers are supported by a bass-reflex enclosure with a large low frequency port, enabling the system to reproduce low frequencies down to 50 Hz.
The M Series allows for both Dual-Channel (Bi-Amp) and Single-Channel (Passive) operating modes that can be set via the accessible selection switches. When switched to Single-Channel (Passive) mode, an internal passive network is engaged that allows users to drive M Series monitors with a single amplifier channel, reducing overall amplifier requirements. Unlike typical passively driven monitors, the M Series splits the speaker preset responsibilities between the amplifier DSP and the internal passive network. The external DSP is responsible for frequency response correction, phase response linearization and component protection, while the internal network is only responsible for the component high-pass and low-pass filters. The combination of the internal and external processing recreates a typical Bi-Amplified speaker preset while only using one amplifier channel. The frequency, phase response and MAX output of the M Series is identical in both the Single-Channel (Passive) and Dual-Channel (Bi-Amp) modes.
The M Series is powered exclusively by Crown iTech HD DSP-based amplifiers; in Single-Channel mode, a single Crown Audio 4x3500HD amplifier can power up to eight M Series monitors (in four independent monitor mixes).
