The VIO S118R subwoofer equipped with a 18" bass reflex woofer is designed to complement the VIO line array systems in the low frequencies.

The system’s acoustic engine is driven by a Digipro G4® 1600W Class D amplifier, equipped with PFC (Power Factor Correction) and SMPS which make the cabinet highly resistant to line voltage fluctuations. Digipro G4 preamplifier features a slot module, equipped with a RDNet expansion card as default, allowing system monitoring and control via Aurora Net. Furthermore, the system is ready for Audinate Dante™ Expansion Card allowing integration in a digital audio network.The amplifier also allows users to run a real-time test on electronics and transducers, both remotely via Aurora Net, or directly on the amplifier module. VIO S118R shows an on-board delay module, allowing to reach a max 62 ms delay via Aurora Net and a max 9.9 ms delay with 0.1 ms steps via on-board rotary. The on-board cardioid preset processes the backward sub in inverted stack cardioid configurations, to achieve the best possible cancellation on the rear side automatically.
