15. INTRODUCTION
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 Q-Pre 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.
