dBTechnologies Presents VIO L1610 Line Array System



Italian pro audio manufacturer dBTechnologies is launching the new member of VIO family: a compact 3-way active line array system equipped with 2x10” woofers and 1 coaxial MF/LF compression driver. A compact PA system able to deliver astonishing power and impressive SPL alongside with the most harmonious and consistent audio performance.

STATE OF THE ART 3-WAY SYMMETRIC ACOUSTIC DESIGN

VIO L1610 is a three-way active line-array system, entirely equipped with neodymium components: 

2x10" woofers (2.5” v.c.), providing an extended LF reproduction, interact with a coaxial neodymium component (4” v.c MF plus a 2,5” v.c. HF compression driver) mounted on an exclusively designed waveguide. 

This unique coaxial symmetric acoustic design results into the most accurate transient reproduction, which enables VIO L1610 to deliver the most detailed and homogeneous audio performance. The coaxial component not only allows an extended low-end reproduction of the MF, but guarantees a perfect off-axis coherence alongside with all the benefits coming from woofer’s direct radiation.



UTMOST AMP TECHNOLOGY

Each VIO L1610 acoustic engine is driven by a Digipro G4 Class-D amplifier module featuring 1600 W RMS along with the utmost acquisitions in dBT’s amp technology.

In fact, the system takes advantage of a one-of-a-kind low latency processing resulting from its powerful DSP featuring linear phase FIR filters. 

Digipro G4 amp comes with a modular slot for expansion cards: as a default, VIO L1610 is equipped with dBTechnologies RD-Net card for real time remote control via Aurora Net software. The system can be upgraded with Audinate Dante protocol for digital audio stream as well as well as real time control purposes. 

As a support for networking purposes, each VIO L1610 cabinet is equipped with Near Field Communication (NFC) system and a frontal LED used to recognize each single module within the remote-control software Aurora Net. On-board controls (2 rotary encoders) allows DSP presets for Speaker Coupling and High Frequencies compensation.



The amp’s power supply is equipped with PFC (Power Factor Corrector) technology, a feature allowing a very stable and consistent performance of the system, regardless of the quality of the mains and power fluctuations. The PSU is 380V resistant, so the final amplifiers will be switched off in case of undesired strike of 380V current.

Exclusive technology of Digipro G4 amplifier is 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 time frame, keeping the overall system’s inrush current low, even in very big PA system deployments.

The amp also allows users to run a test on electronics and transducers before, during and after use. 

VIO’S RIGGING SYSTEM

VIO L1610 comes with VIO series’ peculiar 3-point rigging system allowing a smooth and fast set up of the system. The 2 front links easily connect the modules. The back central rigging strand is equipped with a ring type link allowing user to set the relative splay angles ranging from 1° to 10° thanks to 1 single pin.  Splay angles can be set directly in the dedicated transport cart DT-VIOL210L which houses 4 modules. While lifting up the array, the rigging strand will automatically block the preset angles with no heavy lifting required.

The flying frame DRK-210 allows smooth flying operations and system lifting.  

VIO COMPATIBILITY

VIO L1610 has been designed keeping in mind compatibility among VIO systems. Both its acoustic and mechanical design makes it the perfect downfill for large VIO L212 systems.  TF-VIO2 adaptor allows to easily rig VIO L1610 modules under a VIO L212 array. 

CABINET DESIGN

Each VIO L1610’s wooden cabinet is coated with a black polyurea anti-scratch finish. The amp module is protected by a magnetic rubber raincover (included) designed to provide weatherproofing even when mounted in steep angle as downfill.

An impressive power/size ratio keeps the cabinet to a 31.3 kg (69 lbs) overall weight. Side and rear handles (2 per side) have been designed to furtherly ease transport, set up and dismantling operations.
