The Quickfilter QF-Audio Dragon docking station reference design includes equalization filters, microcontroller firmware, schematics, BOM, and layout files. Docking station manufacturers may personalize the reference design by adding speakers of their choice, custom designed equalization filters (using QFPro1Da software), and plastic enclosure. The QF-Audio Dragon docking station reference design is built around the recently introduced Quickfilter QF1Da512 SavFIRe, the industry's first audio applications-specific single-chip FIR filter solution with integrated gain and compression.

The audio data converters for the QF-Audio Dragon docking station reference design are provided by AKM Semiconductor. The AK5358A (ADC) and the AK4387 (DAC) are used for the analog interface for the QF1Da512 SavFIRe chip. Both devices provide high-quality 24-bit audio at a very low cost point. Ideal for cost-sensitive docking station applications, these devices ensure that maximum fidelity is preserved to enhance the user experience.
