Liquid TechnologyBack top

Liquid Mix provides reliable emulation of a wide range of vintage and classic units. It does this by emulating their sonic behaviour using sintefex's patented Dynamic Convolution; the application of a unique, level-dependant set of responses to an audio signal.
These measured responses, sampled at numerous levels and with a multitude of setting combinations, are applied to the input stream on a sample-bysample basis for extremely convincing results.

Focusrite’s new LIQUID4PRE™ four-channel microphone pre-amplifier utilizes The Liquid Channel™’s proven Liquid™ technology, marrying a hugely flexible analogue front end with cutting-edge dynamic convolution DSP to deliver the sounds of 40 vintage and classic microphone pre-amplifiers across all four channels. Augmented by fully digital controls and remote software control over Ethernet, LIQUID4PRE provides the ultimate fluid multi-channel front-end.

99 Unit Setup Memories provide full recall of every parameter across all four channels, delivering instant multiple user presets and a comprehensive backup of session settings. These memories can be managed either via the hardware, or via LIQUID4PRE’s dedicated control software, LIQUID4CONTROL™. This intuitive software application places comprehensive pre-amp control inside the DAW. Communication between LIQUID4PRE and the DAW flows via Ethernet, with LIQUID4CONTROL providing comprehensive management of multiple LIQUID4PREs. A similar Pro Tools TDM/RTAS plug-in allows integrated remote control via Pro Tools hardware and software, including Icon systems, providing all the benefits of a Pro Tools TDM/RTAS plug-in, such as comprehensive automation and session integration.
Emulations & SettingsBack top
Focusrite's
emulations and settings will help you to make the most of your Focusrite Liquid products. You'll find a growing library of emulations, programs and snapshots, with helpful filters and information regarding the original unit emulated.
Currently, it is not possible to upload individual emulations to Liquid 4PRE (this facility will be included in the next release). So, if wanting to restore factory presets then it must be done in bulk. Click here to download the bulk factory emulations file.
If wanting to find out more about what preamps are included in this download and on the Liquid 4PRE, follow the link to the Liquid Channel emulations listing below.
