Featuring a dual 18” subwoofer pairing in a voluminous bass-reflex housing, VIO S218 encompasses a vigorous audio performance and a ultra low frequency punch, extending down to 28 Hz: the perfect bottom end addition to large VIO L212 sound reinforcement systems. 

 

The system’s acoustical potential is driven by 2 Digipro G4® Class-D amplifiers delivering a total amount of 3200 W RMS and making this sub the perfect low-end extension of VIO arrays in larger sound reinforcement applications. 

 

The switched mode power supply is equipped with PFC (Power Factor Corrector) which greatly improves the efficiency of the system. 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.

 

Exclusive technology of VIO S318 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. 

 

The preamplifier is equipped with a modular slot for expansion cards: as a default, VIO S218 is equipped with dBTechnologies RDNet card, for real time remote control via Aurora Net software. The system is ready for future upgrades with Audinate DanteTM AoIP protocol. 

 

VIO S218 comes with built-in technologies: Near Field Communication (NFC™) proximity sensors are used to determine the position of each box within an array. A LED bulb on the front of the enclosure contributes to help the user to recognize, identify and match each box on the remote control software Aurora Net.

 

Users can run system-test on transducers and a real time impedance control. The on-board delay module allows VIO S218 to reach a max 9.9ms delay with 0.1 ms steps. A cardioid stack preset button automatically process the sound of the backward sub in gradient inverted stack configurations, in order to reach maximum cancellation on the rear side.

 

The preamplifier’s floating audio input design grants a digital optical isolation between earth ground from the mains and the audio ground flowing into the preamplifier board. This galvanic isolation greatly improves resistance to interferences and any unwanted buzzing and noises.

 

Thanks to the integrated USB port, the user will perform firmware upgrades and diagnostics analysis, by downloading telemetry data on system performance and failures.
