The product price includes a one year warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

The Soundcraft Si Expression console brings you the latest DSP, component technology and manufacturing techniques to deliver the most powerful, affordable digital console ever.

Soundcraft's digital consoles have gained a reputation throughout the professional tour circuit for their pure sound quality and intuitive hands-on and user-friendly operation. Featuring a colour-touch screen for an easy set-up, the Si Expression also has dedicated front panel controls for every important function.

The patented FaderGlow system lights each physical fader according to its function, so it's instantly obvious what that fader is controlling, even in dimly-lit circumstances.

Class-leading built-in signal processing comes in the form or four real Lexicon hardware FX engines, dbx compression and a 30-band BSS graphic EQ, permanently assigned to every input and output.

The Si Expression 1 can be controlled from the free iPad™ control app and will also have USB and Firewire interface card capability, making it ideal for both studio and live recording.

Features and Specifications

  • Direct Gain Out Stabiliser: Prevents manual change of a mic gain control affecting direct out levels, perfect when 2 controls share a stagebox or when recording the channel direct outputs.
  • Security Lockout: Lock the whole console or just selected elements, manage the security with the users and profile settings.
  • Assignable Fader Layers: Customise each of the four fader layer pages to meet your needs or add/insert faders to accommodate an additional mic
  • Copy and Paste: Copy whole channels, busses, mixes, Laxicon effects and a single part such as the EQ or multiple parts like the channel gate and compressor.
  • TOTEM: The One Touch Easy Mix, press a single key to mix to an AUX, FX or Matrix bus. The surface and monitoring instantly reconfigure to allow instant mixing to your chosen bus on the faders.
  • BSS GEQ: With a BSS GEQ on every bus there is no need to assign from a pool or resources and you will never 'run out' of processing.
  • 1 Control = 1 function: With each control dedicated to a given function there is never any 'layering' or controls or navigating through screens. This allows the Si Expression controls to be labelled on the surface just as they would have been on an analogue mixer.
  • Global mode controls: A row of rotary controls above each fader assignable at the touch of a button to be GAIN, PAN or HPF for all of the inputs allowing instant access to the core functions.
  • Soundcraft FaderGlow: Illuminates the fader slots according to function with clearly defined colours for FX, Stereo, Linked Mono, GEQ, POST Fade Aux and PRE Fade Aux.
  • Instant Access Keys: Dedicated keys on the front panel for Store, Recall, Next, Mute 1-4, Tap Tempo and more negate the need to dive into screen and context modes.
  • Function Focus: Whenever a control is moved or SELect key pressed the screen displays information about the channel identifying the absolute value of the controls and the channel name, number and more.
  • Everything everywhere: All channels and busses have a full complement of processing, nothing to assign or configure.
