Hi,
I'm having problems with a TW 4:1 mux /demux switch and hope someone can help! I'm using the switch to switch between Optical, SPDIF and AES.
Everything works perfectly until I connect the AES input. Then the output from the AES input comes out whatever source position is selected and any other source does not come out.
I'm using an impedance /voltage converter circuit for the AES input but I get the same problem when using a Canare conversion transformer.
I tried connecting the AES input to another input position and the same thing happens. Anybody any clues as to what's happening?
Thanks
David

Can you sketch out a diagram of the AES connection? AES is usually differential, so would require two lines, but I assume you are converting to a single-ended signal with the transformer. Typically, problems arise when signals are not sharing a ground into the MUX chip.
Hi,
Thanks for the reply. I have used both a resistor output /impedance adapter and a Canare transformer adapter with the same results. In fact, I checked yesterday and the same thing is happening with SPDIF input as well.
