The FiiO R9 and K19 have now officially passed HDMI certification.
The R9 and K19 support HDMI audio decoding, HDMI OUT, and HDMI ARC functions. To utilize HDMI's patented technology and logo, products must obtain authorization from the HDMI Association and undergo compliant design until passing rigorous testing to achieve HDMI certification. At the inception of the R9 and K19 projects, we applied for membership in the HDMI Association, paid annual dues to become official members, and promptly sent mass production versions of the products to the HDMI Association's authorized testing center, ATC, for testing. Upon passing the tests, the testing organization forwards the results to the HDMI Association headquarters in the United States for review.
In addition to membership fees, each product sent for testing needs to pay testing fees and royalties (i.e., copyright fees). After more than six months of testing on various complex projects, the R9 and K19 have finally obtained HDMI certification, indicating the arduousness of this certification process.
It is worth noting that HDMI certification is not mandatory, but FiiO has consistently adhered to a user-oriented and responsible attitude, ensuring product compliance and broad compatibility, allowing users to better experience the enjoyment brought by HDMI functionality. To this end, we have overcome numerous difficulties and applied for HDMI certification for the R9, K19, and some subsequent new products (currently confidential). Hereby we would like to express special thanks to our team members for their efforts and perseverance.
Note: The HDMI-certified versions of the R9 and K19 are HDMI 1.4b; the certified machines are mass production versions, consistent with the ones currently in use by everyone.
