Double AK4399 With Software Control Decoding Module

The product of all parts are original authentic, chastity, pure quality;

The use of high-quality original parts, that is not only guarantee the safety quality , long service life, more important is the powerful guarantee to make the actual performance can meet the design target. The pursuit of first-class quality is our consistent aim.

l  Adopted original AK4399 (2pcs) + WM8805 + NE5534

l  The main circuit of the electrolytic capacitor signal uses the PHILPS famous brand, main filter capacitor using NOVER AUDIO special electrolytic capacitor capacity of 2×4700UF, Coupling capacitance by the top German imports of Weimar capacitor 1UF, adopts the full wave bridge rectifier circuit, ensure the supporting power.

l   The selection of Resistance is five metal resistance, the main circuit adopts the metal film resistor which accuracy is ± 1%, guarantee the signal-to-noise ratio of the product.

l  PCB adopts 1.6mm thickness double-sided board, 2 oz copper thickness, spray tin full process, ensure the current well done through the performance. first-class PCB quality.

l  AK4399 is the high-end decoding chip of AKM, support for 32BIT 192K

l  USB optional
