PT-HDADM is an audio converter used to extract the encoded multi-channel audio from HDMI sources to S/PDIF via COAX and optical audio output and also decode to 2 CHs analog stereo audio via RCA (L/R) without any other external equipment. Content from multi-channel sources such as Blu-ray players, set-top boxes and game consoles can be distributed to multi-channel and two-channel-capable zones simultaneously, ensuring compatibility, reducing system complexity and eliminating the expense of separate dedicated sources for each zone and you can listen to digital audio sources such as DVD and CD players or digital computer audio on your legacy analog sound system, preserving your current investment.
