VMB to Show New Product Series at Prolight + Sound

	VMB's QB Family

VMB has released the brand new ARK series of processors, replacing the Arkeops and DAC range. The ARK-70 and ARK-20 are the latest in the series of digital processors designed, assembled and manufactured by VMB offering seven different models with two or four inputs each and with up to eight outputs (analogue or digital and Ethersound optional).

Double Dynamics are standard in all ARK-70 models. An RMS limiter is used to adjust the transducer reproduction level, maintaining the original dynamics whilst at the same time respecting the original transients and achieving a better acoustical result. A Peak limiter controls the movement of the speaker, protecting it from any damage and also reducing distortion caused by over-excursion. These double dynamics lower levels of distortion and provide protection for all the speaker components and internal electronics.

With 0.5ms fixed latency the ARK-70 is one of the lowest latency processors available. All ARK units deliver a wide dynamic range of 120dB, high performance Cirrus Logic AD & DA 24bit converters running at 96kHZ. The internal DSP processing works with double precision in floating point, achieving an internal resolution of 56 bits, one of the largest resolutions available on the market today. This enables the use of high precision filters with extremely low distortion delivering unbeatable sound clarity and quality.

The ARK-70 also offer atmospheric compensation - essential when working outdoors where temperature and humidity varies considerably between night and day causing noticeable loss in high frequency, especially at long distances. Each output can be configured separately depending on the throw required from each cabinet.

The ARK software has been designed for fast user access to make each processing zone simpler for the user. The Compare function option enables the user to listen to the difference between two complete set ups in real time with no fade-ins or fade-outs. As well as being able to import measurement curves from the principal systems (SMAART LIVE, CLIO, SAT Live etc), they can also be seen directly in the final frequency response window showing the effects of the process applied. All ARK processors can be configured and monitored in real time by USB or ETHERNET. All ARK units can import/export complete channel parameters from/to VMB's Rainbow Prediction Software. This enables the user to apply a complete signal process with just one click.

Each input has up to 29 filters of Parametric EQ which can be switched to Graphic EQ. Each output also has Parametric EQ which can be chosen between adaptable or constant Q, All Pass, Band Pass, Notch, HP Q, LP Q or High and low Shelves providing flexibility. Moreover, crossover filters with high and low cuts of Linkwitz Riley, Bessel, Butterworth up to 48 dB/oct slopes in 6 dB steps are available. A 6 dB/octave slope, for instance, corresponding to a first order filter, allows for frequency shading.

Other features include polarity, gain and delay on ins and outs, routing of any input to any output and a signal generator with sine and noise (pink or white).

The QB series is VMB's latest range of passive cabinets comprising of 9 full-range and 6 sub-bass cabinets. Every care has been taken to design a compact, high performance range of cabinets which offers a complete solution for portable and fixed installation markets. This is why the QB Series comprises 15 models, ensuring that there is a cabinet for every sound reinforcement project, all compatible with one another.

All QB Series components have been carefully selected to offer a lightweight, versatile series delivering dynamic sound whilst remaining as competitively priced as possible and guaranteeing utmost reliability. All cabinets deliver a linear phase response and have been engineered to reduce distortion. The series can boast exceptional coverage with wide horn-drivers fitted to all the cabinets. Cluster configurations are possible to increase both pressure and dispersion whilst maintaining excellent sound distribution and fidelity.

All QB Series Full Range cabinets are supplied with high frequency OCPP protection (Over Current Passive protection) whilst all Sub-bass models come with SWR (Stationary Wave Reduction) to reduce internal stationary waves. All QB Series cabinets are finished in rugged, premium birch plywood and coated with high resistant water-based black paint and a strong steel grille. Cabinets are also available in white on request.

Special attention to detail has been given to offer flexible application solutions ensuring simple and reliable setups. A selection of professional accessories and rigging is available providing installation solutions for any application. For QB Series simulation and planning, VMB's Rainbow Prediction software is available free of charge to all VMB users. Rainbow offers an accurate prediction for any sound reinforcement project with both horizontal and vertical planning available.
