dBTechnologies creates a three-way active line array system
With the VIO L1610, dBTechnologies has created a three-way active line array system entirely equipped with neodymium components: two 10-inch woofers provide an extended LF reproduction and interact with a coaxial neodymium component (4-inch voice coil MF plus a 2.5-inch voice coil HF compression driver) mounted on an exclusively designed waveguide. This coaxial symmetric acoustic design results in an “accurate transient reproduction”, which enables the VIO L1610 to deliver a “detailed and homogeneous audio performance”. The coaxial component is said to allow an extended low-end reproduction of the MF and an off-axis coherence, with all the benefits coming from the woofer’s direct radiation.
Each VIO L1610 acoustic engine is driven by a Digipro G4 Class-D amplifier module featuring 1,600W RMS. The Digipro G4 amp comes with a modular slot for expansion cards and features a special floating audio input allowing a digital optical isolation, reportedly resulting in an even, interference-free input signal. The Digipro G4 also includes IPOS (Intelligent Power-On Sequence), a circuit that controls the sequence in which the main power supplies of all units within an array ramp up. As a result, each module is switched on in a different timeframe, keeping the overall system’s inrush current low, even in very big PA system deployments. The amp allows users to run a test on electronics and transducers before, during and after use.
The system takes advantage of low-latency processing resulting from the DSP which features linear phase FIR filters. As a default, the VIO L1610 is equipped with dBTechnologies’ RD-Net card for real-time remote control via Aurora Net software. The system is also ready for upgrades with Audinate Dante protocol for digital audio streaming as well as real-time control purposes. Each cabinet is equipped with a nearfield communication system and a frontal LED used to recognise each single module within Aurora Net. On-board controls (two rotary encoders) allows DSP presets for speaker coupling and high-frequency compensation.
The VIO L1610 comes with the VIO series’ three-point rigging system and the two front links are said to easily connect the modules. The back central rigging strand is equipped with a ring-type link, allowing users to set the relative splay angles ranging from 1–10° thanks to a single pin. It has been designed to be compatible with other VIO products, such as down fill for large VIO L212 systems.
