The DSC260 provides two inputs and six outputs that can be assigned to either or both inputs. Typical applications include stereo three way systems. The unique flexibility of the DSC260 allows each output to be tailored to the exact requirements. This allows mono systems with up to six bands or a combination of mono or stereo crossovers and delays. The user can select the slope and type of crossover as well as frequency, polarity, level and limiter thresholds. In addition, up to 30 bands of EQ can be assigned to inputs or outputs eliminating the need for additional outboard equipment. Signal delays can be assigned to any input or output independently and can be linked to other channels for stereo or delay tower operation. To assure optimum acoustic performance, careful consideration was given to the overall circuit design including high quality 20 bit A/D and D/A converters as well as minimal analog circuitry. The DSC260 achieves a very low noise floor, smooth amplitude response, and maximum dynamic range.
