Soundcraft Si Impact 40 Input Digital Mixer

With more than 40 years' experience in live sound mixing to draw upon, it's no surprise that Si Impact joined forces with Soundcraft to bring some of the latest in digital mix innovations together.

The ultimate live and studio digital mixer for those who refuse to compromise on sound quality

The Si Impact 40 Input Digital Mixing Console from Soundcraft has been designed to be as intuitive to use as an analog mixer, whilst offering an array of radical workflow enhancements. These include the unique FaderGlow system, a huge amount of DSP power, and an incredible 32-in/32-out USB audio interface.

World Class Digital Effects

The Si Impact's DSP power comes courtesy of world-renowned experts in digital FX. Packed full of studio-grade reverbs, delays and modulation Lexicon, as well as legendary dbx dynamics and industry-standard BSS Graphic EQ's, you'll never be short of options.

DAW Ready

The built-in 32-in/32-out USB recording and playback functionality of the Si Impact help make recording directly to your DAW both quick and easy. A single connection to your computer allows you to make multitrack recordings, sending up to 32 inputs and 32 outputs worth of signal to your workstation.

Free 2.0 Firmware Update

Now with a free firmware upgrade to version 2.0, Soundcraft are giving you even more impressive features to play with. This upgrade allows you to combine the 32 mix inputs on the console with all 32 USB inputs, giving you a massive 64 total channels to mix!

With the addition of a Soundcraft Mini Stagebox 32i or 16i, you can get up to 64 mic channels to mix, or with a second MADI option card and two Mini Stagebox units you can achieve an incredibly 96 microphone preamps, 128 total available inputs, and 80 mixable channels.
