The Pro-Ject Audio Box S FL DAC uses a filterless, non-oversampling conversion technique based on the Audio CD format at 16 bit and 44.1 kHz. Conversion is performed by four TDA 1543T integrated circuits in a parallel Dual Differential Mode configuration, for accuracy and low distortion across the audible range below 20 kHz.
The SMD output stage is connected directly to the digital-to-analog converters, so no additional filtering is required. The heat sink helps dissipate heat during operation.
