Going Beyond Analog Control

Delivers analog workflow with digital flexibility

One of the Soundcraft Si Impact's strengths is that it provides you with a simple analog workflow while also offering you the flexibility that you can only obtain with a digital mixer. One-knob-one-function control means you won't have to jump around the board to change parameters, while the FaderGlow system ensures that you know exactly which functions are being controlled by which faders simply by looking at them. Each fader channel also provides you with a clear multicolor LCD display, giving you quick at-a-glance information on your levels and a fully customizable "scribble strip" to name your channels.

  • One-knob-one-function control
  • FaderGlow system
  • Clear multicolor LCD displays

Graham Blyth-designed mic preamps and "British" equalizer

Like all Soundcraft mixers, the Si Impact is positively packed with that highly sought-after "British" sound. Thanks to its stellar-sounding mic preamps (designed by Soundcraft founder Graham Blyth) and 4-band, fully parametric "British" equalizers, the Si Impact provides you with a sound that will imbue your mixes with plenty of classic distinctive character.

  • Sought-after "British" sound
  • Graham Blyth-designed mic preamps
  • 4-band parametric EQs on each channel

World-class Effects

DSP processing from Lexicon, dbx, and BSS Audio

Featuring studio-grade reverb and effects from Lexicon, legendary dbx dynamics, and industry-standard BSS graphic EQs, the Soundcraft Si Impact's onboard DSP carries quite a pedigree. Thanks to these world-class effects, you'll be able to create polished, pro-sounding mixes without a rack full of outboard gear.

  • Lexicon reverb and effects
  • dbx dynamics processing

With built-in connectivity for their optional stagebox, Soundcraft's Si Impact lets you put your I/O wherever you need it.

It's about the sound, plain and simple

To start with I'm a little bias towards Soundcraft products. For sixteen plus years I owned a Soundcraft Ghost Le 32 as the front end for my MOTU-Digital Performer system. The punch, clarity, transparency and overall build quality was outstanding. Moving towards an all "In-the-box" system I upgraded my Motu devices, added the Mackie MCU Pro to the mix for tactile feel and hit the ground running. Using the same monitors for both systems (5.1 Genelec and 8030c and 7050C) I noticed a difference immediately with the sound quality however this is understandable give the lack of a proper channel strip. Through multiple plugin I eventually was able to approximate the total quality of my Ghost. Jump ahead a few years and I started doing live streaming of my band and found I needed additional stereo outs(six plus)for dedicated headphone and streaming mixes. Initially I thought of changing out to the newer generation of Motu AVB products, having been happy with quality of multiple previous devices then I started looking into digital mixers.

We purchased an Behringer X32 rack for our live show in-ear system. Having been using firewire and PCI based systems for years I didn't expect the USB2 outs to be able to cleanly transfer all of our live inputs in the DAW as well as it did. Physically, it did the job however tonally it sounded very much like the existing audio system. Nice but one-dimensional.

I started reading up on the Soundcraft Impact, the expansive inputs and outputs along with expansion capabilities along with 32 USB in-out I decided to give it a try. The promotional info stated "The legendary British sound" but I must admit I was skeptical. After installation all skepticism was thrown out the door. The tone is back! After intensive reading and configuration I was able to configure all of the inputs and outputs, get all live inputs mapped to DAW for 32 channels my initial reaction was "Tone? Where have you been all the long lost years!

Microphone inputs, both condenser and dynamic sound rich and full, even without the addition of EQ. Even when I add additional EQ or compression to the channel it doesn't over color the sound. AKG, Shure, Rode and CAD mics all sound fantastic. Direct connections of keyboards and outboard gear is just as impressive. No need to gain stage the channels as they all were, for the most part, perfect out of the box.

Although I do have external Lexicon effect units the four built-in units sound fantastic.

The network capability of the board allows for external control via iPad or iPhone for basic functionality. I do wish more of the controls were available via iPad however I can just as well run over the board to make it. Each band member has control of their individual mixes.

As we are testing streaming live performance via YouTube or Twitch I'm able to change the audio balance, including EQ and effects levels from other rooms on TV, computers and Smart Phones from within my network. Extremely helpful to hear outside of the studio!

Using the flexibility of the mixer to provide the individual no-latency headphone mixes while sending the audio the DAW is a true wonder.

Wish list:

I use a lot of VST's and AU's in my project and have found a very slight bit of lag when using CPU intensive plugins. Not sure if it is the USB2 that is causing the bottle neck with the IO or not. Since I have been using firewire and thunderbolt this is something that hasn't been that much of a problem. It would be nice if there was a thunderbolt 3 card option available. Nothing on the horizon as yet.

Perhaps I'm missing it however I would like the Impact effect to be able to sync with MIDI time (Delays etc)

To be honest one or two more outputs would be great as 5.1 and six headphones don't quite fit however that's what patch bays are for!

If the response of remote connection from iPad is so smooth it would be great to translate that into MIDI machine control to respond to my automated fader responses in my DAW. I would rather fade the Impact VCAs or individual tracks and not fade out or volume adjust in the DAW.

Ok my wish list may be big however I can't recommend this desk any higher! As mentioned in the title audio creation is based the quality of the audio sound quality. If the quality is there the product can't help but be better.

This is a perfect project desk for any environment and considering the footprint and flexibility I'm looking forward to creating and performing with it for years to come.

Fantastic job Soundcraft. Equally fantastic job Rob Parker for steering me in the right direction for this purchase!

Soundcraft SI Impact

I didn't think I'd be good at using a digital mixer but the SI Impact proved me wrong. I've always done sound jobs with analog mixers. Then a sound company I was working with told me to leave my mixer at home, they'll have a mixer there. I was told what it was and for two days I studied and studied what I could find on line about the Prosonis live mixer. I had no idea about the channels needing to be assigned or how the fat channel was all about or how to turn it on per channel. We'll, that first job sucked, then a second job was better but I still had issues on how it worked. Although I ended up with a good house mix and Eq, the band had issues with me….hmmmm, I wonder why.
That was it for digital mixers until!! I saw a sound guy using a Soundcraft performer, I was hooked on how it worked, he showed me how easy the mixer was. Just fader glow turned me on and the 29 band Eq on every output, wow!! Well, I ended up buying the SI Impact and used a friends band as my Guinea Pig except I played with it at the house for a couple of weeks first. Needless to say, that job went exceedingly well. Then had another job with that band, then I used it to mix some of the very best Rush Tribute bands. Yes, I was hooked on this mixer. The sound, features and size was a great treat.
I would buy this again, I didn't get to record from this mixer yet but everything I saw on line looked like it would be pretty easy. The stage box is impressive as well and I still am amazed how everything can go through a little CAT 5 cable.
I highly recommend the Soundcraft digital mixers. The only thing wrong is, unlike analog mixers, you can't see what's turned on or off in a daylight or outdoor sound job. You have to totally block it from any sunlight hitting the board.
Yes, I still highly recommend this mixer….

Best Mixer ever for churches!

This is by far the best mixer for churches ever built. It is very user-friendly.I have been working in sound most of my life. I am a musician and a piano tuner, Songwriter and recording tech. I hesitated when digital mixers first came out to get one because of the complexity of use. But now this mixer in my mind makes it easier to operate than any analog! Okay, so you'll have to read up some to set it up, but you can easily run it with very little experience. For example, your sound man never shows up and the service is about to start. Grab an usher, show him what snapshots (presets) to use and your all set. He can just tap on the name of the snapshot and the mixer will recall everything you need. Setting up snapshots is as easy as setting a few levels and pushing a button. Okay, so it sounds easy and it is yet this mixer has tons of bells and whistles for the professional user. Tons of awesome special effects and sound processors and can handle all your output needs. Need a separate mix for several monitor systems along with a separate mix for the nursery, podcast, lobby, and recording? No problem! It can handle that and much more. Would not hesitate to recommend this mixer for a small or large church. Or many other venues for that matter. It's a Godsend!

Too good to be true!

Our team at church recently purchased the Si impact along with the Stagebox 32R. Upgraded to the version 2, we are literally blown away by the dynamic processing (dbx) and the capability of the lexicon effects. The studer preamps were so clean. The total customization of the faders under each bank and the ability to route direct outs to various destinations makes this mixer to good to be true for the price. If anyone is looking for a quick transition from an analog to digital, look no further. We also purchased the Aviom out card which works seamlessly. We are grateful to Alan Carter for his prompt response and advises with regard to equipment and shipping. Thank you Sweetwater. God bless you guys! The best retailers for music equipment. (Mic drop)
