The DiGiCo SD9 is a compact, yet fully-featured digital mixing console that delivers professional-grade audio processing and workflow efficiency in a streamlined footprint, making it a versatile choice for live sound, broadcast, and theatre applications. As part of the renowned SD Series, it inherits the same core FPGA-based processing engine and proprietary Stealth Digital Processing found in its larger siblings, ensuring pristine sound quality, ultra-low latency, and robust reliability. The console provides a substantial channel count, often configurable with up to 72 input processing channels and 36 mix busses, all operating at a 96kHz sampling rate for high-fidelity audio reproduction. Its interface centers on a crisp, high-resolution TFT screen flanked by dedicated rotary encoders and tactile, color-coded buttons, offering an intuitive and fast workflow that allows engineers to access deep functions without extensive menu diving.

A hallmark of the SD9's design is its highly flexible and customizable control surface. It features 12 fully assignable faders, allowing any channel, group, or output to be placed under physical finger-tip control at any time. The console includes comprehensive processing on every input and output, including four-band parametric EQ with dynamic EQ options, multiband compression, gates, and delays. Its integrated effects rack provides a suite of high-quality reverbs, delays, and dynamics tools. For system integration and expansion, the SD9 is equipped with DiGiCo's proprietary Optocore fiber network ports, enabling seamless connection to a range of stageboxes and supporting redundant audio networking for mission-critical performances.

Built into a durable, tour-ready chassis, the SD9 balances power with portability. It supports extensive snapshot and show file management, allowing for rapid recall of entire show configurations, which is invaluable for theatre productions and touring acts with consistent setlists. The console also offers sophisticated macro functionality and support for external control via MIDI or Ethernet. By packing the sonic integrity and operational depth of larger consoles into a more accessible format, the DiGiCo SD9 has established itself as a go-to solution for engineers who require top-tier performance and flexibility without the physical size and complexity of a full-scale production console.
