AIE Board in Right AIE Slot – Extract Function
Audio is extracted by the AIE Board on the output side for use in supplemental audio equipment as well
as remaining intact as HDMI with embedded audio from the output to the destination device.
AIE Boards in Both AIE Slots – Insert and Extract Functions
On left – embedded audio is extracted from standard input side and is sent on for audio processing.
On right – inserted audio replaces embedded audio on HDMI signal and is sent to the destination device.
Note: When audio is routed through a separate Audio Matrix Switcher, the audio can be inserted
back into the original system on multiple audio insert/extract connectors.
Important: When audio is “extracted” from an HDMI signal, the audio also remains intact as
embedded audio on the HDMI signal.
