Advanced Amplification Technology: The dB Technologies VIO S118R is equipped with the Digipro G4® 1600W Class D amplifier, ensuring high power output and excellent efficiency. The inclusion of Power Factor Correction (PFC) and Switch Mode Power Supply (SMPS) technologies enhances the subwoofer’s resilience to voltage fluctuations, maintaining optimal performance in varying power conditions.

Seamless Integration and Control: The Digipro G4 preamplifier includes an RDNet expansion card as standard, enabling easy system monitoring and control via Aurora Net. Additionally, the subwoofer is Dante™ expansion card-ready, providing the option for digital audio network integration, ideal for large-scale, professional audio setups.

Real-Time Testing Capability: The VIO S118R amplifier offers real-time testing of electronics and transducers, allowing users to run diagnostics remotely through Aurora Net or directly on the amplifier module. This feature simplifies maintenance and ensures consistent operation during demanding performances.

Time Alignment and Delay Management: The subwoofer includes an onboard delay module that offers up to 62 ms delay via Aurora Net and 9.9 ms delay with 0.1 ms steps through an onboard rotary control. This enables precise time alignment, ensuring optimal synchronization with other system components for smooth audio playback.

Cardioid Configuration for Optimal Sound: The VIO S118R features an onboard cardioid preset that processes the backward subwoofer in inverted stack cardioid configurations. This automatically optimizes rear-side cancellation, delivering clearer bass without unwanted noise or feedback from the back of the speaker.

Robust Design for Durability: Built with multiplex plywood and polyurea paint, the VIO S118R is highly durable, ensuring it stands up to the demands of professional environments. It also includes convenient handles for transport and an aluminum pole mount for easy setup in various venues.
