Enjoy the innovation of digital mixing without compromising on audio quality with the Si Impact from Soundcraft. This 40-channel digital mixer is built on decades of expertise in live sound mixing applications, combining the simplicity and intuitive operation of a classic analog mixer with the enhanced workflow made possible with digital. As a result, Si Impact is an ideal mixing solution for live sound performances and studio recordings alike.
Premium features of the Si Impact include the unique FaderGlow™ system, massive DSP power, and a pristine 32-in/32-out USB audio interface. Another characteristic of this digital mixer is its flexibility and scalability, which allow you to customize your audio setup to meet the specific needs of your application, as well as change and grow that setup to fit fluctuating audio requirements in the future. This mixing console incorporates 32 mix inputs as well as 32 USB inputs—offering a total of 64 channels to mix.
The Si Impact is also compatible with Soundcraft’s Mini Stagebox 32i or 16i (sold separately) to expand your system to a total of 64 mic channels. To achieve up to 128 available inputs and 80 mixing channels, you may also add a second MADI option card (sold separately) and two Mini Stagebox units. A Dante option card (sold separately) is another alternative that allows you to take advantage of audio networking technology for up to 64 Dante channels to mix.

More about Soundcraft’s Si Performer Digital Mixers
Bring unparalleled power and performance to small-format live sound mixing with Soundcraft’s Si Performer. This series of digital mixers delivers the equivalent of 448 RU of DSP—including 4-band fully parametric EQ, full dynamics processing, a comprehensive range of output options, totally flexible routing, and flexible integration options. Whether you’re crafting a new system from scratch or looking to upgrade and existing setup, Si Performer mixers are an ideal component to help your audio shine.
Multitasking that goes beyond “just” audio. Si Performer incorporates a DMX 512 controller so you can mix your sound and adjust your lighting rig—all from the same piece of gear. Use the built-in FaderGlow™ motorized faders to automate your lighting. This two-in-one solution is ideal for applications that require optimal flexibility, such as educational facilities, houses of worship, theatrical companies, and conference productions.
All Si Expression consoles have busses, output processing, and connectivity. The 14 aux/group mixes can be configured as 14 mono mixes, 8 mono plus 6 stereo mixes, or almost anything in between. The 4 matrix mixes can be mono or stereo as needed. Four more mix busses are dedicated to the Lexicon FX processors to provide a variety of sounds, adjustable parameters, and dedicated tap-tempo keys. Each bus mix features a compressor, 4 band fully parametric EQ, graphic EQ, and delay.
Effects are hardware-based, ensuring that even the most demanding FX programs won’t interfere with other functions of the mixer, such as settings for dynamics, PEQs, filters, delays, and all bands of all 31 graphic EQs. Control is streamlined via the control surface’s comprehensive, yet intuitive layout with dedicated controls for every parameter, a row of global mode encoders, and an easy-to-use color touchscreen.
Each model’s connectivity includes 16 mic inputs, 16 analog line outputs, 8 analog line inputs, a headphone monitor out, an AES I/O, a 64x64 option slot, and a 64x32 expansion slot for using Si option cards such as the CAT5 or optical MADI. The MADI card interfaces to multi-track recording systems or plug-in systems like Waves, as well as enables linking to any of the Soundcraft or Studer stageboxes to extend the I/O power and flexibility. (All external components are sold separately.)
