Achieving higher purity of sound quality
• The PURE AUDIO indicator lights up,
the fluorescent display goes off and all the video-
related circuits are turned off, meaning no video
signal transfer.
• When the pure audio is activated, the optimum
surround mode (or stereo mode, etc.) will be
automatically selected depending on the signal
format being input.
• Press this button again to cancel the pure audio
function.
