If you're looking at this, you probably already know about the Liquid Channel. It's a classic high-end piece: a massively flexible analog mic preamp coupled with modeled compressors, running at 192 kHz, with analog and digital I/O. They originally sold for $3,000.
This one is in great condition with a few minor nicks from rack-mounting, as shown in the photos. It's priced lower than some recent sales on eBay; get a bargain here, and save me from the hassle of shipping.
Here's what Focusrite has to say:
"The Liquid Channel is a revolutionary professional channel strip that emulates a plethora of classic mic-pres and compressors. Combining radical new analogue pre-amp technology with Dynamic ConvolutionTM techniques, The Liquid Channel fuses cutting-edge analogue design with lightening fast SHARC DSP.
What is 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.
Why the analogue pre-amp?
Mic-pre emulation 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’ pre-amplifier, able to match the input impedance and signal path (transformer or electronic) of the device being emulated."
