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?
Wow. So you are saying that even though the sx20 microphone level shows as disconnected, audio is passing? How can I confirm this without a second codec? I need to hook up a biamp nexia real soon.
We use BlueJeans
Dial 220.127.116.11 or bjn.vc (enter meeting ID 111# and # when prompted). You'll see a parrot. Talk to him, and he'll repeat.
The voice is distorted to sound like a parrot I guess. But that will confirm that your Mic is able to transmit.
