seem use sharc dsp for this device
anyone can ask for a version for sfp too


This is achieved through a unique two-part process. Firstly, the use of Dynamic Convolution™ techniques is applied, utilising lightning fast SHARC chips applying unique level-dependant impulse responses to every sample of audio. However, whilst this is more than sufficient to identically re-synthesise a compressor’s sonic behaviour, in order to replicate precisely every subtle nuance, the pre-amplifier must physically match the way in which the classic unit interacts with a given microphone. The Liquid Channel’s solution to this problem lies in its vast analogue front-end. A pre-amp with the ability to change its impedance and vary its signal path to either transformer or electronic, perfectly replicating the interaction characteristics of the original, whilst remaining entirely transparent within the signal path.
