Lynx converters have won acclaim for pristine transparency and imaging while providing industry professionals with the means to capture perfor- mances with all their subtleties and nuances. Acknowledging the high bar set by this level of performance, the LM-PRE4 was designed with strict requirements for noise suppression and ruler- at frequency response while operating over a wide range of gain settings. In support of this, criti- cal attention was focused on component selection, circuit board layout, and power delivery. The resulting combination of preamp and conversion technology in the LM-PRE4 offers sonic detail typically lost in the all-in- one interfaces. The performance of the microphone preampli er alone meets or exceeds popular stand-alone devices on the market.
