◆DSM (Discrete Surface Mount) Technology

The DSM (Discrete Surface Mount) manufacturing process com- bines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manu- facturer to have invested millions into this process. DSM compo- nents differ from conventional discrete components in three different ways. They are more compact, more rugged, and they take much better advantage of the PC board to allow them to get rid of any heat they generate. Using them wherever appropriate allows the advantages associated with discrete circuitry to be retained while also providing room for both highly advanced processing features and generous PC board copper paths where needed. Their short lead-out structures allow maximum audio performance and highest signal-to-noise ratios to be obtained in amplifiers of desirable package size without resorting to “ampli- fier-on-a-chip” shortcuts. These advantages are shown below in Figure 1.

THE RESULT: Fewer connections, improved reliability, shorter signal paths, superior signal-to-noise ratio and awesome sonic performance.
