INTRODUCTION In purchasing the new SM PR4, you have acquired a multi-channel pre-amplifier of high class that meets many of the demands of the home/pro studio. The market size for digital audio interfaces and computer based digital editing has increased in a massive way. With systems available at very low prices, more and more users are utilizing this technology. One of the main problems with many of these systems is the input stage only consisting of unbalanced line inputs or very low (or no mic pre) gain structure for the balanced input stage and the unavailability of Phantom power. The PR4 comes to the rescue with 4 channels of balanced input, with a full range of gain control from -20dB to +40dB and Phantom power for every channel. This half rack unit can now solve many of the connectivity issues which are raised in a large range of situations, whether in the Studio, home, club installation or other live sound applications. 2.

This ensures robust quality and confidence in performance under all conditions. 3.
