A/V Switching HDMI, de-embedding audio and extending

    We have two racks about 185 feet apart.

    Rack #1 (Main mixer portable rack) has two HDMI sources that need to go into a 2-port switch which will de-embed the audio from the HDMI (to be sent into Main mixer) and send the signal to the 2nd rack.

    Rack #2 (Stage manager's rack) should have a 4-port HDMI switch, with the sources being:
    - Rack #1
    - Wall-plate extender from stage floor pocket (about 90 feet away)
    - Two local sources.
    The switch should de-embed the audio from the HDMI (to be sent into Auditorium assembly mixer) and send the signal to a projector located about 150 feet away.

    I've attached a diagram.


    Can you recommend the gear that will accomplish this (switches and extenders)?

    Thank you for your patience!

    1) For the switches in Portable Rack and Manager's Rack you could consider KD-PRO2X1 and KD-PRO4X1 Or VS-211UHD and VS-411UHD.
    These will de-embed the audio, allowing you to separately send the audio to a mixer from each switch.

    2) To extend from Floor Box to Manager's Rack you could choose HDMI/VGA AV Wall-Plate Extender Kit with wall-plate transmitter and box receiver, or WP-571 (black or white) wall-plate transmitter with PT-572+ box receiver.

    3) To extend from Portable Rack to Manager's Rack, and from Manager's Rack to projector, you could choose from a wide selection of HDMI extenders, or take a closer look at the following:
    HDBaseT HDMI Extenders
    HDMI Extenders
    TruLink HDMI over CAT-5 Extenders
    4K HDMI HDBaseT Extenders
    4K HDMI HDBaseT Extenders
    XTENDEX HDMI HDBaseT Extenders
    HDBaseT HDMI over CATx Extenders
    HDMI over HDBaseT Extenders
    You might want to go with a model supporting 4K (even though you only need 1080p) becuaw it's newer, uses more modern technology and supports a longer distance.

    4) As an alternative to 1) and 3) you could use a switch that already has a built-in transmitter into it, such as VP-440 with a matching TP-580R Receiver unit. This will eliminate the need for a Transmitter box at the rack and will also allow for a local monitor at the rack.

    Hope this helps!
