Description
The dB Technologies VIO S218, 2x18" Powered Subwoofer in larger sound reinforcement applications, VIO S218 is a simple, effective dual sub configuration designed to enhance the reproduction of the lowest frequencies, boosted by an advanced DSP control and complete network capability. 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.
As a default, VIO S218 is equipped with dBTechnologies RD-Net card, for real time remote control via Aurora Net software. Furthermore, the preamplifier is ready for future upgrades with Audinate DanteTM AoIP protocol. To help users in this configuration, S218 comes with built-in technologies: Near Field Communication (NFC) proximity sensors are used to determine the position of each box within an array. This technology, together with a hi-brightness LED bulb on the front of the enclosure, contributes to help the user to recognize, identify and match each box physical position on the remote control software Aurora Net. The amp also allows users to run auto-test on electronics and transducers before and after use and a real time impedance control. This unique system ensure tour-grade reliability and remote control over your entire PA’s health. A cardioid stack preset button automatically process the sound of the backward sub in gradient inverted stack configurations, in order to reach maximum cancellation of the rear side. The on-board delay module allows VIO S218 to reach a max 9.9ms delay with 0.1 ms steps.
