The Soundcraft A947.043100SP is an expansion module designed to extend the analog input capacity of the Soundcraft Vi1 digital mixing console. As a compact and self-contained unit, it provides an additional 16 microphone/line input channels, each equipped with the console's signature SuperAnalogue™ microphone preamplifiers. This expansion is critical for larger productions where the base console's local inputs are insufficient, allowing engineers to connect more microphones, instruments, or line-level sources directly at the front-of-house position without immediately needing to deploy a full digital stagebox system. The unit connects to the main Vi1 console via a dedicated, high-bandwidth digital cable, ensuring pristine audio quality and low latency.

Integration is seamless, as the added channels appear natively within the Vi1's control software and are treated identically to the console's internal channels. Each of the 16 inputs features a combo XLR/TRS jack, phantom power per channel, and individual gain control accessible from the console's surface or remote control software. This allows for precise gain staging and source management directly from the main mixing position. The module is housed in a robust, portable enclosure that matches the aesthetic of the Vi1 console, making it a cohesive part of the system whether placed on a tabletop or mounted in a rack using optional hardware.

For users who require incremental expansion, this 16-channel input module offers a perfect balance between cost and capability. It bridges the gap between using only the console's built-in inputs and investing in a larger, more comprehensive digital snake system. By providing immediate access to high-quality preamps and analog-to-digital conversion, it enhances the Vi1's flexibility for touring bands, corporate events, or installations that have growing input requirements while maintaining the console's renowned audio fidelity and streamlined digital workflow.
