Soundcraft Si Expression 3 - 32-Channel Digital Mixing Console with 4 Line Inputs and 66 Input Processing Channels in Dark Blue Finish

The Soundcraft Si Expression 3 is a 32-channel digital mixing console that offers professional-grade performance, flexibility, and ease of use for live sound, studio recording, and broadcast environments. With 32 recallable mic preamps, 4 line inputs, 4 stereo FX returns, and a powerful 64x64 expansion slot, the Si Expression 3 provides the versatility to handle up to 66 input processing channels, making it ideal for complex audio setups. Its compact and intuitive design, paired with Soundcraft's renowned audio quality, makes it a perfect fit for both seasoned audio engineers and beginners alike.

Each input processing channel on the Si Expression 3 is equipped with dedicated processing features, including a high-pass filter, input delay, gate, compressor, and a 4-band British EQ, ensuring complete control over each audio source. The console's FaderGlow technology provides color-coded feedback for easy identification of the fader's function, ensuring that you never lose track of your mix. Additionally, the One Touch Easy Mixing (tOTEM) system enables you to quickly assign and mix channels to the 14 aux/group busses, 4 matrix busses, and 4 internal FX engines, streamlining the mixing process.

With 14 configurable aux/group mixes, the Si Expression 3 allows for flexible routing of mono and stereo mixes, tailored to your specific needs. The console's powerful output processing includes compressors, 4-band EQs, BSS graphic EQs, and delay processing on every bus, ensuring full dynamics control. The built-in Lexicon FX processors provide studio-quality effects, including reverb, delay, modulation, and pitch effects, with up to 12 adjustable parameters per preset and tap tempo control for real-time adjustments.

The Si Expression 3 is designed for seamless integration into larger audio systems with its extensive I/O options, including 16 balanced line outputs, AES in/out, and the ViSi Connect 64x64 expansion slot. This allows you to easily connect to stageboxes, multi-track recording systems, and other digital audio formats such as Dante, MADI, and CobraNet. Additionally, by adding a stagebox, you can increase the number of input channels you can mix, further expanding the console's capabilities.

The console's control surface is designed to be intuitive and easy to use, with a dedicated control for every parameter and a color touchscreen for patching, routing, and setup. Global mode encoders provide quick access to key settings across all channels, including input gain, high-pass filter, and pan controls, ensuring that adjustments can be made quickly and efficiently. The Si Expression 3 also features a snapshot control system that allows up to 1000 cues to be stored and recalled, perfect for complex productions that require precise transitions between scenes.

The Si Expression 3's reliability is bolstered by the latest generation EMMA DSP processor, delivering legendary Soundcraft audio quality across all 32 channels. The console's durable construction, with a robust metal chassis and integrated power supply, ensures it is built to withstand the rigors of professional use in live and studio environments. The console also features a headphone output and a 12V lamp connector for easy monitoring and control in dimly lit environments.

Whether you're mixing for live performances, recording sessions, or broadcast productions, the Soundcraft Si Expression 3 offers the power, flexibility, and ease of use that professional audio engineers demand, all in a sleek, compact design.
