We are trying to connect a SX20 microphone port to the output of a Polycom soundstructure C12.
I'm wondering if anybody has been successful doing this?
It looks like the SX20 has to be tricked to believe its microphone is connected.
Maybe by sending some power on some pins?
I've seen several example on how to connect powered mics directly to the SX20 but the soundstructure output port is different and the codec keep the port shut when plugging it in.
Has anybody been able to connect a soundstructure or similar device to a SX20?
