BASS-REFLEX POWER
The perfect partner for VIO L212 in larger sound reinforcement applications. 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.
BUILT FOR TOURING
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.

REAL TIME CONTROL
• VIO S218 is equipped with dBTechnologies RD-Net card, for real time remote control via Aurora Net software.
• 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.

CARDIOID PRESET
• 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.
