I've got a Next Receiver that has 1-2 HDMI outputs with enhanced sounding and very easy to use. But the problem is I don't have the instruction on how to operate it. I lost the manual. Where can I get a copy of its instruction manual? Please send me the link. Thanks.
I have got full manual instructions for your Next Receiver HDMI outputs. You can download full instructions in PDF format from the given link.
