2x12” neodymium woofers (3” v.c.) placed to the outsides in a dipolar arrangement provide an accurate transient response and an extended and controlled low-end reproduction.
The mid-range section is mounted in the center of the cabinet in a horn-loaded configuration which dramatically contributes to the system’s acoustic efficiency. Midrange frequencies are delivered by 4x 6.5” neodymium woofers (voice coil 2”).
The 2x 1.4” neodymium compression drivers (voice coil 3”) have been mounted to a waveguide which contributes to create a cylindrical wavefront, much to the advantage of the system’s intelligibility and throw capabilities.
Each VIO L212 acoustic engine is driven by 2 Digipro G4® Class-D 1600W amplifiers, providing each system with a total of 3200W RMS. The switched mode power supply is equipped with PFC (Power Factor Corrector) which greatly improves the efficiency of the system. Performances of the amplifier are very stable and consistent, regardless of the quality of the mains and fluctuations. This also grants a worldwide compatibility of the power supply (from 100V to 240V 50/60Hz) and limits power consumption.Furthermore, the power supply is 380V resistant, so the final amplifiers will be switched off in case of an undesired strike of 380V current, saving them from any damage.
The amp allows users to run system-test on electronics and transducers before and after use and a real time impedance control.
The preamplifier’s floating audio input design grants a digital optical isolation between earth ground from the mains ant the audio ground flowing into the preamplifier board. This galvanic isolation greatly improves resistance to interferences and any unwanted buzzing and noises.
The USB port allows firmware upgrades and diagnostics analysis, by downloading telemetry data on system performances and failures.
Exclusive technology of VIO L212 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.
