How to use SPDIF output in KA13?
Als u de SPDIF-functie moet gebruiken, schakel dan eerst de SPDIF OUT in de FiiO Control APP Android-versie in. Sluit vervolgens de KA13 aan op de coaxiale ingangspoort van een ander apparaat via een speciale 3.5 mm naar RCA-coaxkabel, tevens te verkrijgen bij AudioZaal. Het pindefinitiediagram is als volgt:
