The Soundcraft Si Impact is a 40-input digital mixing console and 32-in/32-out USB audio interface that supports remote iPad mixing using a proprietary app. The console is designed to be as simple as an analogue mixer, but offers workflow enhancements such as the FaderGlow system, which illuminates each fader track in different colours to provide at-a-glance status information on precisely what the fader is controlling.

Featuring studio-grade reverbs, delays, and modulations from Lexicon, dbx dynamics, and BSS graphic equalisers, the Si Impact comes fully equipped to mix everything from rock bands to stage plays. Also a 32-in/32-out USB audio interface, the Si Impact mixer delivers professional digital recording directly to your DAW, and comes with a free download of Ableton Live Lite 9.

DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
