Can anyone help to identify what the circled part of this image might be?
I am working to create something similar to the image above... Essentially a portable sound cabinet of sorts.
I have pretty much been able to identify everything here except the item in the top right corner. It appears to have an XLR output that connects to a mixer. This connection seems to allow all of the wireless mics to connect to an existing sound system. It also seems to function as an antenna connection for the UDH box to the left.
Any ideas on what this part is? I imagine the rear must have inputs for all three of the receivers.
