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 consisting only of unbalanced line inputs or very low gain structure for the balanced input stage and the absence of phantom power.
The PR4v from SM Pro Audio provides four channels of balanced input, with a full range of gain control from -20dB to +40dB and phantom power for every two channels. This half rack desktop unit can solve many of the connectivity issues that occur in the studio, home, club installation or other live sound applications.
