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.
