High Sound Quality:
This Audio DSP board employs the Analog Device ADAU1701 whose signal processing is compara-ble to that found in high end studio equipment. The dynamic range of its Two Σ-Δ ADCs and four Σ-Δ DACs reaches high up to 98.5dB. Each ADC has a THD + N of -83 dB, and each DAC has a THD + N of -90 dB. Besides, the optimal PCB layout of power filtering and signal loop as well as the capacitive compenents also contribute to the high sound quality.
