Harman to exhibit at Prolight + Sound 2012 the new Vertec VTX

Harman Group Company JBL Professional to Exhibit at Prolight + Sound the new line array series, the Vertec VTX, which brings new developments in terms of transducers and other electro-acoustic aspects, incorporating the new D2 Dual Driver, which significantly improves treble reproduction capability.

The new Vertec VTX from JBL Professional will be playing live at the Prolight fair + Sound, in Frankfurt (Germany) of the 21 to the 24 March 2012. It will be a unique opportunity to attend a demo of the new V25 line array from the group's firm Harman in multi-array format with supporting subwoofers, Crown VRack amplification with HD V5-grade BSS Omnidrive signal processor and Soundcraft Vi Series mixing consoles. The system is configured to perform a multimedia presentation, which consists of a 360º immersion in the latest lighting technologies, sound, Video and automation that exist today.

The JBL V25 model is a box of 3 tracks formed by 2 15" 2267H Speakers, four 8" 2169H and 3 D2 treble motors with two plastic ring diaphragms that allow you to go up to the 20 kHz due to the lower mass of the same. The powers it handles are 2000 Wrms in bass, 700 Wrms in Media and 300 Wrms in treble, in all cases to 8 Ohms. The horizontal coverage is 90º between 250 Hz and 16 khz, and the frequency response ranges from 35 Hz to 20 Khz (- 10 db).

New D2 engine

These speakers use JBL's Differential Drive technology with a dual coil and dual magnetic field system, together with radiators integrated into the aluminium chassis to dissipate heat. The new D2 double-diaphragm, double-coil compression driver overcomes the limitations given by the masses of these elements, by combining these dual elements into a single compact transducer, with its unified acoustics. The D2 Dual Driver uses two coils, each with its own diaphragm, magnet and phase connections. Like this, instead of having a single heavier coil with its metal dome, typical of conventional compression motors, the D2 motor is powered by two coils that work as two driving forces, acoustically connected to a single output chamber.

As with the rest of Vertec's models, Radiation Boundary Integrator is used, so the 8" are placed in a V shape on the sides of the output of the treble waveguide and as in the other cases it is also covered with a trumpet with grooves. The waveguide uses a resonant chamber (TRAC – tuned resonant absorption chamber) that improves horizontal coverage and eliminates cancellations caused by rear pressure of the mid-section. This ensures an uninterrupted and distortion-free transition between bands.

The S.A.F.E. flying system. Suspension is also new. Designed for easier angle adjustment and no mechanical noise. The new "dolly" with wheels makes it easy to transport and hang. Each box, in addition, Optional laser can be incorporated for easy system orientation. Thanks to a new aluminium front, the space between sources has been reduced and the height of the box has been reduced by 8 cm compared to model VT4889, being only of 41 cm. Weight, 82'5 kg per box.

Crown VRack is recommended for amplification, composed of stages of the IT HD series with BSS DSP. They are available in two versions: VRack 12000 with 3 stages IT12000HD and VRack 4×3500, with 3 IT stages 4x3500HD. The Racks are pre-wired and include a connection panel for audio and another for power.
