40 Classic Mic Pres and 40 Vintage Compressors!
The Focusrite Liquid Channel is a revolutionary professional channel strip that can precisely replicate virtually any classic mic-pre and compressor ever made! Combining radical new analog pre-amp technology with special Dynamic Convolution techniques, the Liquid Channel fuses cutting-edge analog design with lightning fast SHARC DSP. Augmented by fully digital controls and optional remote software, The Liquid Channel provides the ultimate fluid vintage collection.Focusrite Liquid Channel at a Glance:
- Replicates behavior of vintage units for authentic sound
- True analog preamp stages with both transformer and electronic impedance matching
- Special harmonic distortion control lets you match your favorite preamp
- Digital processing with 192kHz sample rate ability
- Expansion and remote control options
Liquid technology for accurate sound replication
Rather than creating a similar sound to vintage units, as with modelling devices, The Liquid Channel precisely replicates their sonic behavior. This is achieved through 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 every possible setting combination, are applied to the input stream on a sample-by-sample basis for accurate replication.
Mic-pre replication can't be achieved with software alone. Hardware is required in addition to account for the physical interaction with the microphone. As a result, Focusrite invested vast amounts of time and energy into designing and building the ultimate 'liquid' preamplifier, able to match the input impedance and signal path (transformer or electronic) of the device being replicated.
Not all vintage units are born equal
Second order harmonic distortion is a beneficial artifact of analog circuits (especially tube and transformer-coupled designs) providing the much-loved "warmth." However, often two units of the same type will vary in the amount of second order distortion produced, so an additional control for modifying this vintage property is provided. This allows for precise matching of the Liquid Channel to your own beloved mic-pre.
The best of both worlds - analog and digital
The Liquid Channel combines a highly complex, massively flexible analog front-end with Dynamic Convolution processing, which utilizes lightning-fast SHARC chips and runs at sample rates of up to 192kHz. The front panel controls are digital, with tactile rotary encoders; all parameters can be stored in one of 99 program memories. At the press of button, you can reload all mic-pre, compressor and EQ settings for an individual session. If using the Liquid Channel in conjunction with a recording platform (e.g. Pro Tools), both the session files and The Liquid Channel's program memory can be sent via standard data transfer methods, providing a completely mobile recording session. Perfectly replicated vintage classics with the power and ease of use of the digital domain.
Infinite expansion and remote control
The USB port on the rear panel allows remote control of The Liquid Channel, leaving the processor safely racked away. But that's not all. The software application also serves as an archiving system for additional replicas and program memories, and permits downloads of additional classic units. So, the Liquid Channel is infinitely expandable.
